The real story here is that IP ownership is capital-intensive when it shouldn't be. Open-source and community-led IP contributions are grossly under-protected because of this, and those with capital become unopposed predators. This is a special-case of the more general observation that the justice system is capital-intensive when it shouldn't be. The answer is something you very rarely hear: the US (especially) needs justice system reform with an eye toward making actions take 100x less time and 100x less money, approaching free for consumer and IP actions. Given the advent of computers, the internet, video conferencing, it is outrageous how much of the current system requires physical paper, physical presence in a courtroom. It is outrageous how the slowness and cost of the system itself is used by the wealthy to bully the poor.

IP is just too strong. The terms are ridiculously long (especially for copyright), there are multiple workarounds for "fair use", such as DMCA, and patents on simple concepts like linked lists are not laughed out of the room.

All of this stuff needs to be weakened (and shortened). Part of the reason Chinese companies are able to iterate quickly on technology like 3d printers or drones is that it's possible to simply ignore this stifling IP regime until you actually need to start selling internationally.

It's telling that the article specifically calls out patents originating in China. It seems ridiculous to treat these as serious filings and not shredder fodder when the originating country happily allows their local industry to ignore western patents. The asymmetry here leads to obvious advantages for Chinese companies.

While I don't entirely disagree with you. You have to understand why the courts exist at all. To govern working class citizens. Laws are written by the powerful and wealthy - always has been - to control the working class (everyone else).

You're freedom is an illusion. A social contract agreed upon by you following certain rules. Those rules, written by the wealthy, don't apply to the wealthy. In a just society they would be, but we have ceased to be a just society for the last 50 years. Technology isn't going to solve this without becoming that AI overlord everyone is scared of. Court systems are designed to prevent working class from becoming wealthy and to protect the wealthy and their assets from the working class. (violent crimes aside)

> In a just society they would be, but we have ceased to be a just society for the last 50 years.

When did we start being a just society would you say? WWI? The Civil Rights Act? Unless you really stretch things, saying that justice declined in the last 50 years - even if true - means that justice "peaked" for a short period of maybe a generation. I suspect if you actually lived in that era[1] you wouldn't think that though so this whole framing is based on false nostalgia for a time you never experienced.

Arguably justice in general started declining with the invention of the typewriter, and injustice accelerated with the invention of the word processor and will get far worse with LLMs. The cost and time of litigation scales like n^2 where n is the textual length of the law. Personally I'd like to require that laws be written out by hand by the lawmaker(s) proposing them (NOT their staffers), and read aloud by them before a vote.

> I'd like to require that laws be written out by hand by the lawmaker(s) proposing them (NOT their staffers), and read aloud by them before a vote.

I could really get behind this sort of rate-limiting. It would also make the thinktank-written legislation a little less appealing for the lawmakers, as they'd still need to write everything out.

AlexandrB · 8m ago
My counterargument would be that before the typewriter literacy rates were much worse than they are now. So while it's true that laws were simpler, interpreting those laws was still out of reach for many at the bottom of the economic ladder. It would be interesting to try to compare legal complexity with the percentage of society that has a sufficient reading comprehension to meaningfully interact with those laws across various eras.
bryanlarsen · 16m ago
> When did we start being a just society would you say?

I think most historians would agree that it started with the signing of the Magna Carta in 1215.

It was a very small start, it only protected nobles from the king, but it's generally considered to be the start.

AlexandrB · 7m ago
If that's the standard, it's ridiculous to say we stopped being a just society in the last 50 years.

Just going off my own experience. While violent crime has diminished, other crimes are going on in plain sight with prudence from the courts. Because privatized prisons are a thing in the US, they need product... You'll be charged $4/day - $80/day while you're there. I remember when "debtor's prison" was illegal. Now it's not. So you can brush it under a rug, claim things are better, claim we are more just than we used to be, but I never claimed that we ever were 100% just. Only that we used to be more just than we are today.

Probably 50s-70s? The golden age of capitalism oddly enough. Among other things taxation maintained a more even wealth distribution during this time in many western countries. Combined with a record large generation that had few children and parents that dies in wars (almost everyone working), this lead to a surplus. When there is a surplus the overlords are generous. Now that generation is old and dependent on the handful of children they had. There is no longer a surplus. There is hope that the technologies we are creating could bring enough productivity gains to return to surplus conditions, but the population decline that will have to overcome is extreme. IP laws aren't encouraging these productivity gains like we need them to, so we should ignore them. The west deciding to ignore chinese IP won't be the thing that starts the war, and it isn't like china ever respected the IP of the west. We should be buying up all the tooling we need to painfully bootstrap automated manufacturing ourselves and reverse engineer it.

"Justice" is not a scalar. It is a matrix, at best.

In some parts of America, and in some aspects, "justice" was still clearly increasing up until the second Trump presidency. This is especially true for the treatment of various marginalized groups (especially queer people, where it's quite obvious that "justice" for them increased markedly with the Obergefell v Hodges decision in 2015, and continued to improve in many ways after that).

In other areas and ways, it peaked before 9/11 and has dropped a great deal since.

In still others, it's been on a long slow decline since some time in the latter part of the 20th century.

And this is part of why some people are so angry these days: they see "justice" decreasing for them, while it increases for other people—including some of the people they've always considered to be beneath them—and they wrongly conclude that it's a zero-sum game, and they need to reduce justice for those other people in order to bring it back for them.

That would bring down the price of patent spam even more. The problem is the cost of protection relative to the cost of attack, you can't do much.
dcow · 19m ago
But it would also make patent spamming much less valuable and arguably more expensive for the spammer. If you spam patents and get one issued for something that isn't novel and/or already has prior art, everyone can fight it and it quickly gets its metal tested in court.

I imagine a fine for egregious patents could also be implemented. If your patent is demonstrated in court to lack standing, the civil liability is on you, not the patent office.

The hard reality is that nobody actually knows a priori what innovation is. Or how much an innovation is actually worth. If you removed patents that would pretty easily and trivially stop the spam.

RobotToaster · 59m ago
It would allow anyone to patent spam though, that could be a good thing.
brookst · 37m ago
How? Compare to email spam where the cost is zero. Is that in any way better than a world where it takes substantial capital to send email spam?

Lower cost = more patents = more patent trolls = less innovation.

It would be good if the difficulty of getting patents would go up by a factor of 10. To get less of them in volume, and less bullshit ones. Should also throw out a bunch of the existing bad ones.

The fact that IP protection is expensive is essentially its defining feature. One way to think of "intellectual property" is precisely as a weird proof-of-work, since you are trying to simulate the features of physical property for abstract entities that by default behave in the exact opposite fashion.

This is the frustrating thing about getting into an argument about how "IP isn't real property" and then having the other side roll their eyes at you like you are some naive ideologue. They're missing the point of what it means for IP to not be "real property". The actual point is understanding that you are, and will be, swimming against the current of the fundamentals of these technologies forever. It is very very difficult to make a digital book or movie that can't be copied. So difficult in fact, that it we've had to keep pushing the problem lower and lower into the system, with DRM protections at the hardware level. This is essentially expensive, not just from a capital perspective, but from a "focus and complexity" burden perspective as well. Then realize that even after putting this entire system in place, an entire trade block could arbitrarily decide to stop enforcing copyright, AKA, stop fueling the expensive apparatus that is is holding up the "physical property" facade for "intellectual property". This was actually being floated as a retaliation tactic during the peak of the tariff dispute with Canada. And in fact we don't even need to go that far, it has of course always been the case that patents vary in practical enforceability country to country, and copyrights (despite an attempt to unify the rules globally) are also different country to country (the earliest TinTin is public domain in the US but not in the EU).

Usually at this point someone says "It's expensive to defend physical property too! See what happens if another country takes your cruise liner". But that's precisely the point, the difficulty scales with the item. I don't regularly have my chairs sitting in Russia for them to be nationalized. The entities that have large physical footprints are also the ones most likely to defend those resources. This is simply not the case with "intellectual property," which has zero natural friction in spreading across the world, and certainly doesn't correlate with the "owner's" ability to "defend" it. This is due to the fundamental contradiction that "intellectual property" tries to establish: it wants all the the zero unit-cost and distribution benefits of "ethereal goods," with all the asset-like benefits of physical goods. It wants it both ways.

Notice that all the details always get brushed away, we assume we have great patent clerks making sure only "novel inventions" get awarded patents. It assumes that patent clerks are even capable of understanding the patent in question (they're not, the vast majority are new grads [3]). We assume the copyright office is property staffed (it isn't [2]) We assume the intricacies of abstract items like "APIs" can be property understood by both judge and jury in order to reach the right verdict in the theoretically obvious cases (also turns out that most people are not familiar with these concepts).

How could this not be expensive? You essentially need to create "property lore" in every case that is tried. Any wish for the system to be faster would necessarily also mean less correct verdicts. There's magic "intellectual property dude" that could resolve all this stuff. Copyright law says that math can't be copyrighted, yet we can copyright code. Patent law says life can't be patented, yet our system plainly allows copyrighting bacteria. Why? Because a lawyer held of a tube of clear liquid and said "does this seem like life to you?" The landmark case was decided 5-4 [4], and all of a sudden a thing that should obviously not be copyrightable by anyone that understands the science was decided it was. There's no "hidden true rules" that if just followed, would make this system efficient. It is, by design, a system that makes things up as it goes along.

As mentioned in other comments, at best you could just flip burden to the other party, which doesn't make the system less expensive, it just shifts the default party that has to initially burden the cost. Arguably this is basically what we have with patents. Patents are incredibly "inventor friendly". You can get your perpetual motion machine patented easy-peasy. In fact, there is so much "respect" for "ideas" as "real things", that you can patent things you never made and have no intention of making. You can then sue companies that actually make the thing you "described first". Every case is a new baby being presented to King Solomon to cut in half.

In other words, an inexpensive system would at minimum require universal understanding and agreement on supremely intricate technical details of every field it aims to serve, which isn't just implausible, it is arguably impossible by definition since the whole point of intellectual property is to cover the most newest developments in the field.

If you are a hobbyist or small business in desktop manufacturing you are basically forced to buy Chinese products.

I have never owned a Prusa, but I have owned several Creality and Bambu Labs printers, because I could get the same utility at half the cost. The same goes for soldering irons, linear actuators, oscillscopes, etc. I still buy European hand tools (Knipex, Wera, etc) because I know they won't break in a year, so they are good value in the long run.

Often the choice is whether to buy a used, last generation tool of eBay, or a brand new next-gen tool from China. The choice depends on how flawed the Chinese implementation is and the gap in utility between the generations.

The main problem with Chinese products is the lack of accountability. The same product will be sold under multiple brands, or by dropshippers, and you have no idea who actually made it, there are some strong Chinese brands that buck this trend, i.e. Bambu Labs. When you buy western tools you are buying peace of mind, something I can't currently afford.

zevon · 31m ago
Prusa makes their products locally, the spare part situation is good, the company runs an open Makerspace in their basement, helps host conferences and has done a lot for Open Hardware in general. They also have offered consistent upgrade paths for old machines for a long time and the repairability in general is good. You can also talk to them. These things matter for purchase decisions. Same logic as per your Knipex and Wera example.

I actually have a Bambu Labs at home for occasional use but I would not consider anything but Prusas for a general-use desktop FDM printer in basically any more serious setting. This has been the situation for many years now (over the last 12 years or so, I've had to make a few purchase decisions for batches of 5-15 FDM printers as well as different single specialty ones).

hyperbovine · 4m ago
I want so much to like Prusa ... but the Bambu printer at my local makerspace costs half as much and is better in every way than the MK3S+ sitting in my basement. I'm fully aware that this is the result of shrewdness on the part of the Chinese, plus incompetence in the West, and it's so frustrating.
jononor · 43m ago
Forced I don't know... But of course the financial incentives are very strong, as in many categories the Chinese brands have remarkable and sometimes astonishing value-for-money. But for a small business, the cost of these tools might be quite low relative to manpower anyway, so paying 2x might not be a big deal. We got 8 Prusa machines at our local hackerspace, and 10 at previous startup lab I was at.
alnwlsn · 35m ago
Chinese stuff these days has pulled far ahead of the Harbor Freight reputation of my youth. I can't remember the last time I've seen a proper "Engrish" instruction manual, most of the things are well designed and well built. Meanwhile, the "good old American brands" seem to just be selling out for cheaper and better profit margin products, so you'll be ending up with Chinese stuff anyways, which is sometimes worse than the actual Chinese brands.
Workaccount2 · 33m ago
The Chinese stuff is now more often than not better. You cannot be the world's manufacturer for 30 years and not get good at making stuff.
AlexandrB · 34s ago
I've recently been putting together a large aquarium build for the first time in ~15 years, and it's really shocking how good and how cheap the Chinese stuff is now. Of particular note is lighting, where the price/W on non-Chinese equipment is 4-10x the Chinese equivalent.
tempest_ · 5m ago
I always think it is amusing that some people make the mistake of thinking that the Chinese can only make cheap crap(forgetting all their cell phones and apple laptops come from there).

The American market only wants to buy cheap crap so that is what is made and sent. Usually though the skills involved in making something cut-rate are just as applicable to making something top notch.

American manufacturing skills have atrophied as it has moved to a service economy while as you say the Chinese have been boosting manufacturing for 30 years.

Hobbyists aren’t forced to buy anything.. I blame youtube for turning hobbies into an exercise at buying stuff. Affiliate links are one of the few ways to make money online and the reason why the majority of videos in the hobby space seem to be gear reviews. Yet as a hobbyist chances are you won’t practice enough to outgrow your tools anyway, and neither do you have the economic incentives of business owners.
the__alchemist · 1h ago
This is a microcosm of what's happening all over the physical device world, and manufacturing: Everyone (Except Prusa; thank you for your service!) outside of China is forgetting and losing capabilities.

My Raise3D printer is high quality and reliable. It's a nice piece of hardware. The PCBs I order from JLC are high-quality, built-to-specs, and whenever there's an error, it's a design fault. They are cheap, and arrive in 10 days.

I don't like the idea of being this dependent on China, but it's where we are. Weaponizing patents a risk? Problem. Placing the knowledge of how to build civilization in a single country? Problem. At least someone is carrying the torch forward, so it could be worse.

As a hardware guy, and someone who loves coming up with fun product ideas, China is the ASI LLM of the hardware world. Like don't even bother trying to compete, they are faster, cheaper, have better yield, and don't really need to be profitable.

Imagine what the software industry would look like if an LLM could look at any completed software product, and a few weeks to a month later have made a perfect copy of it. It would totally kill any drive you have to make a product.

That's the current reality of hardware in the western world. About 5 or 6 years ago I developed a product that cost me $75 in parts per unit (probably $60 if I could get to scale). The Chinese counterparts competing in the same category cost $70. I needed to sell at $200 to make a profit.

People seems generally uninterested in fixing this too. Those $800 Chinese printers are extremely capable after all.

megaloblasto · 33m ago
I have a feeling that soon, proprietary software won't be a business moat at all. No mater the complexity of your software, it will be too easy to replicate. That could be a good thing for open source. One way of staying ahead of your competition is to control the most popular open source repo.

Dependence on foreign power with potentially misaligned goal? Collapse of manufacturing sector, leading to rise in poverty?
ninetyninenine · 15m ago
There is no misaligned goal. China isn’t out to destroy the US.

It’s more jealousy of being overpowered. It’s sad but I think this is ultimately the brutal truth we have to accept. There’s no other logical outlook on this. Literally if left to its own devices China isn’t interested in the war.

The US is out to do everything to stop Chinas ascendency to become the new world power. And of course both sides as a result will increase military presence but neither side wants to engage in war.

Workaccount2 · 54m ago
Being entirely dependent on Chinese manufacturing to make anything. This also has the downstream effect of no one young learning how to make stuff, which then leaves you as a society that is forced to buy everything from China, and puts China in an excellent position to rug pull American society if they want.

I can tell your first hand, that the engineers in the hardware/physical product space probably have an average age of 58 years old. That's very bad.

motorest · 15m ago
> Being entirely dependent on Chinese manufacturing to make anything.

I'm sorry, it's very hard to take this sort of concern seriously.

The express goal of US's take on neoliberalism was to dump all manufacturing onto countries like China while abusing IP to prevent anyone else, China included, from ever being able to compete.

Now that the rules that the US abused to stifle innovation are being used by someone else to protect their own investment, you suddenly cry foul?

The US needs to put on their big boy pants and figure out ways to compete in the same terms that everyone else had to endure, just like the whole world was forced to learn how to deal with that. If someone else has the IP you need, pay them. Or do you honestly expect that arbitrary rules are only acceptable if they clearly benefit you alone?

Workaccount2 · 43m ago
China, being a planned economy at heart, has a "VC" system that is essentially just the government deciding what needs to be developed, and then Chinese banks lending without any practical strings to those developers.

Profit and loss, ROI, business plan, aren't really factored in. China wants to develop AI? You have some experience and want to start an AI business? Great! Here is a few million go make AI.

This is the system that led to those infamous ghost cities and billion dollar high speed trains to nowhere. China puts the carts before the horse, and hopes at at least a few of them get to the destination. They're not unfamiliar with burning tens of billions to get a few hundred million of value.

It also means that if you are competing against one of these chosen industries, you are not competing, because they are just burning daddies money, whereas you need to make interest payments.

I don't see how that could be considered a planned economy, you're describing individuals creating startups of their own free choice and the government backing them with no strings. Individual choices are driving economic progress.

A planned economy would be some government committee deciding what specific startups and how many of them should be started up in any give year, and no one else can create a startup.

Not IP related, but I built a Voron printer a while ago, which is sort of the last word in DIY printers. It's not so much a printer as a parts list and set of instructions, but something that's not lost on me is that most of the core components are Chinese parts.

I don't just mean screws and bearings (though they are too), you might install a board like this [0] which is a Chinese designed board I'd describe as open-ish. You get the firmware and schematics, but not a BOM or board layout. But that doesn't really matter, because nobody is going to make this board themselves anyways, you're going to buy it assembled, from China. There are other boards, but they are more expensive.

The majority of Voron builds use Chinese hotends. There are a lot of custom "for Voron" kits and components being made and sold there. Can you find a PEI coated-spring steel bed that isn't made in China? So while it's definitely more open than a Bambu printer, it's not really any less dependent on China.

I guess it would be technically possible to do a "no China" build, which would be an interesting (but expensive) project.

Even if the patents are only valid in China, this is going to hurt western companies a lot. If you're manufacturing a product in China, you'll need to either:

1. Pay the patent trolls, giving them power and hurting your margins

2. Move manufacturing to a more expensive, less competitive country

In the long run, you could argue that point 2 will lead to domestic manufacturing which everyone wants. But unless you can find a way to make these companies actually competitive (e.g. tariffs on chinese printers), I think the more likely scenario is these hamstrung companies will wither and go out of business.

This could have been an interesting take from anyone but Prusa. While they've earned themselves a great deal of goodwill from past contributions to the ecosystem, they're a failing company pivoting to dark patterns in an attempt to cling to relevance. It's heart breaking to see they still haven't been able to take a good hard look at themselves, and understand their own role in why they are scrambling.

Blog posts like these might be heralding the beginning of the end for Prusa.

A genuine Question. Is open hardware even possible at some point? The advances in quality and speed are nothing short but impressive. I started 3d printing stuff in my basement one year ago (Ender V3 Plus). With the quality and speed improvements, comes technology which gets more complex every year. Companies spend millions to archive this. Why would they share it? I remember building drones in my basement (still on my wall) with open source software on the flight controllers. Now I can get a drone from DJI for less money with more features, in a smaller from factor, longer flight time, pre build and under 249g. Ofc this comes at the cost of repairability, control and trust. However I can still buy the hardware I used years ago. If I wanted to, I can build a drone by myself. I guess the same will happen to 3d printers.
mystraline · 45m ago
> Is open hardware even possible at some point?

It already is. And its been chaotic and amazing at the same time.

We already have open source:

5DoF 3d printers with slicers

Fixed wing and quad/hexa/octocopters

Medical drug fabrication (Four Thieves)

Electrochemical synthesis lab

Open source flow batteries

Stops and starts of industrial tooling (open source ecology)

I'm going to say something that is becoming less and less controversial: copyrights and patents are the real drag here. Individuals can get patents, but can't actually enforce. So they end as weapons as companies go after each other.

Copyright is also often intertwined into patents, so that if a thing isn't covered by a patent, copyright (with firmware) takes over. Then the DMCA and anti-circumvention shit.

The other problem here in the USA is almost impossible to source parts directly, or small fab labs that can do operations.

I was looking for a 5mm thick 500x500mm aluminum plate to be cut. Waterjet, plasma, whatever. I wanted it slightly undercut. I made blueprints in DXF and pdf. I contacted 2 waterjet companies, no response. Contacted a welding company with plasma table. No response. Down the list, no response.

As a creator, how am I supposed to create, when all avenues lead to "source it in China"? That... Is huge.

Open hardware for 3D printers is actually thriving. There's a whole fleet of community designed hardware, with most innovations to consumer 3D printing still originating in the DIY community.

Multiple manufacturers have direct contact with community members to produce custom hardware at a small but affordable scale, and keeping up with rapid iterations and multiple hardware improvements throughout the year.

Some of the most cutting edge as well as niche 3D printing hardware available to consumers are being sold on small webshops operating out of someone's garage.

If anything, we're in a golden age right now. 3D printing in 2025 is a very exciting place to be.

As a person who chose to buy an Elegoo Centauri Carbon rather than upgrade his Ordbot Quantum w/ a heated bed and enclosure and to then try to re-design it to use a CoreXY motion system, I would agree that is exactly the path which we are on --- the new printer came in at a lower price than just the initial parts order for heated bed and enclosure, let alone a different motion system. All of the printers which I wanted (Positron, Prusa Core One) or was considering (Bambu Labs P1S) were over twice or almost twice the price of the ECC.

That Elegoo seems to be supporting open standards: https://www.tomshardware.com/3d-printing/elegoo-launches-aut... was one thing which allowed me to justify placing that order.

Citation from blog: > The fact you hold a prior art in your hand, doesn’t mean much. The patent will still prevent you from importing/selling etc of the “infringing” stuff.

Could you please explain this to me? Let's say, they (Chinese) patent some complex part of my open-hw 3D printer, how this prevents me from importing parts of my 3D printer from other countries? Let's say from China. Company, which originally patent trolled me, must sue me first, no? And they care about patents? Since when?

sokoloff · 18m ago
Suppose you hold the original prior art and want to get your original design manufactured on China. The Chinese manufacturer might the best in the world and cheapest source but unwilling to defy the Chinese patent.

Your tiny order isn’t worth their whole business, but if you did the original design that feels patently* unfair to you.

* sorry, couldn’t help myself

TFA didn't really make the problem clear to me. I think it something like this, but I'm not sure. Can anybody clarify?

Problem (?): We can't produce open hardware for things that others have patented. Chinese companies (and maybe others) are patenting lots of things, including things we might have ourselves developed and intended to keep open, so it makes it difficult and/or expensive for us to continue developing.

Is that it?

For most people this is just fine - your goals were not to build a 3d printer it was to build something that just happens to be build able on a 3d printer. That is the something you are building is the goal, not building a 3d printer. If the goal isn't building a 3d printer then buying a 3d printer that someone else has already debugged and made to work is the better way to get to what you really want to do in the first place.

In a way this is good. 3d printing is neat, but it got too much hype which was taken away from other useful things makers should also have experience in. More makers should think of injection molding when doing plastic parts. Many plastic parts makers are making would be better as metal done on lathes and milling machines (or if you want to have fun shapers and planers - both obsolete but still a lot of fun if time/money isn't important). Wood working has never really lost popularity, but it should be mentioned as a good option for makers. There are also cloth options - sew, knit, spin, tat (my favorite). There are plenty of other ways to build something other than 3d print.

Finally along those lines, for some just drawing something up in CAD and sending it off to someone else to make is a good option. FreeCAD has come a long way finally has reached 1.0, or you can pay for one of the commercial options - some of them are reasonable for makers though read the fine print.

Yes but the fewest come at the price and versatility as 3D printing. Injection molding is very expensive and hard to do in the basement. Wood working too, requires lots of time, skills and many tools...

bluGill · 34m ago
> Injection molding is very expensive and hard to do in the basement

You can make everything in your basement, just like you can make a 3d printer in your basement, and for similar prices. Almost nobody does it, but that doesn't mean it can't be done.

> Wood working too, requires lots of time, skills and many tools...

Skill is developed. You can do woodworking with just a sharp rock you find, no need for any more tools. Most people in woodworking choose to trade money for time and buy a lot of tools, but you can decide how far you want to go.

Time is the real constraint for everything of course. However that is my original point - if your goal isn't building a 3d printer (a fine goal) then trading money for time and buying the tools (which might or might not be a 3d printer) is probably you best bet. Assuming you have money to buy a 3d printer of course, but if you don't than a sharp rock and woodworking is probably your best hobby just because it is what you can afford.

As it happens with FOSS anything, that is not what the general public cares about, rather getting something easily at a store and fulfills their needs, which aren't how the thing works, rather as a tool for their actual work.
bluGill · 49m ago
You have limited time. That year needed to build and debug a 3d printer (if you are single a year would be way to long, but for those with kids that is way too short) is a year that you can't spend on whatever your real hobby is. If you real hobby is 3d printers then that is great, but if not you shouldn't. I work on FOSS projects, but most of what I have installed on my system is a per-packaged distro from someone else who made it work (I have FreeBSD, Ubuntu, and Arch - each slightly different) because I don't have time to do linux/BSD from scratch even though I could. I have built gcc, but most of the time I just use the pre-packaged gcc so I can get on building the project I'm interested in.

> But around the year 2020 we registered the first mention of 3D printing as a strategic industry by the Chinese government. We know that now, after a few years of research. We first realized something is off when the price of the parts is higher than the sale price of a complete machine in some cases. That is what sparked our interest and research into the subsidies. They exist, and are very efficient https://rhg.com/research/far-from-normal-an-augmented-assess.... Our industry, desktop 3D printing, faces a bleak future. Comparable to the automotive sector as if only one high volume car brand, say Audi, remained outside of China. That’s it. An inch away from complete dependency on China in an vital piece of tech, the one absolutely critical for creation of new IP.

It seems like the real problem here is that China is able to identify strategic industries, subsidize them, and see the subsidies result in increased production and lower prices, while Western countries aren't. I'm not sure if Prusa themselves can do anything about it, but unless the West gets its shit together and decides to actually try to compete, it seems like eventually every advanced manufacturing industry will be mainly Chinese.

Well they quite literally steal everything you push out. Anyone who’s done it out in the wide open knows this reality. Sometimes they will have the copy out faster than you. What’s the point? And customers do not care at all. I heard it so many times. People lack moral compass because they grow up in environments where you’re rewarded for stealing and cheating.

I am still waiting for video encoders and decoders patents to go away so we could have easy open source implementations that are royalty free, not patent incumbed to be easily available in open source applications that could be also commercial. We don't have any decent easy to go ones since Theora.

As someone that had open-hardware printers, they suck. They were fun to play with but not really ready for every day use.

So perhaps a bad thing for the hardware side, but as a consumer/user I want a smooth experience.

zevon · 47m ago
That is hardly a function of the printers being Open Hardware. There are lots of unreliable commercial printers as well as fiddly open ones. However, the most reliable ones in the desktop space have mostly been open - like the old Ultimakers or the Prusa MK series.
sublimefire · 16m ago
This is very much a bad faith argument without any specifics. I found Prusa to be good enough. Do you have any examples of open hardware printers that were evaluated that did not meet the bar?

Regardless the topic is about open hardware being squeezed using shady tactics. It means leas competition, less innovation. Rules to kick such players should be easy to enforce as opposed to required to pay quite a lot for such an action.

Symbiote · 27m ago
Prusa's printers have a reputation for being easy to use, but cost more than the Chinese competition.

Hi! Josef here! I was just recently sharing a little update on socials, here is a copy:

Since I posted my “OHW is dead” article, you’ve been asking me about “that patent”. I didn’t want you to miss the forest (thousands of filings since 2020) just because of one tree. But let’s take a look now. In this case: the MMU multiplexer (we open sourced it 9 years ago). Anycubic (another IDG Capital-backed company) used the tactic of filing in China for an easy initial grant: CN 222407171 U > DE 20 2024 100 001 U1 > US 2025/0144881 A1. The playbook: file a Chinese utility model (10-year patent, same protections, lower examination, already granted) claim that priority in Germany (again as a utility model, already granted) file in the US. Cheap to file, but expensive and time-consuming to fight. I already wrote why prior art isn’t a magic wand that solves it immediately in my article ⤵ And there are many more, we just found a new juicy one!

Edit: Emojis stripped from the original, tried to fix it a bit ;-)

All of Open Source needs a sunlit patent pool, a searchable database of documented inventions AND all of the follow on ideas around them. This could provide a way to force patent examiners to do their jobs and allow the Open Source Community to crowd source invention bombing the proprietary world.

How does one lookup these patents? They need more exposure so they can be refuted.

I work in a different industry, power tools. Somehow the USPTO allowed Milwaukee to patent a circ saw that spins at a certain rpm...

The things that get through the patent office are braindead. Patents are just weaponized legal minefields now. They've totally lost their original intent.

Better printers came along, were not "open", but they were easier to use and maintain especially for first-time hobbyists and even for print farms.

While I'd lean more towards plain ol' capitalism as the reason for small market players going under, the final point of the article (discussing patent related legal barriers on existing open source innovation becoming a main strategy of large industry players) is a very important one to keep in mind for people on this site in the hardware startup space:

"This is a story from 3D printing, but all the areas with heavy open hardware development are in Made in China 2025 https://en.wikipedia.org/wiki/Made_in_China_2025 and its successors. Make sure you keep an eye on the filings around your expertise, it is incomparably much easier to do something now than later."

He seems to point pretty directly to Chinese subsidies allowing those printers to be sold under cost. That’s not capitalism.

RobotToaster · 49m ago
Amazon operated under cost for years to capture the market, how is this any different?
trentnix · 36m ago
Also partially subsidized by the government, who charged their mom-and-pop brick and mortar competitors sales tax while Amazon avoided subjecting their customers to sales tax for many years. That, plus Amazon's ability to operate at a seemingly perpetual loss, was absolutely predatory.

And the government sat on its hands and our representatives loved all the Prime boxes stacked at their doorstep. It has ensh#ttified entire industries that once depended upon retail as their interface with customers.

I think what you meant to say is "that is not an enforced fair and free market" which is much different than capitalism.

How's it not capitalism? If your definition of capitalism requires governments to either not exist or not act to improve the conditions of their subjects (including companies), you have a definition of capitalism where basically none existing or only failed states have a capitalist system.

Private companies spending (and potentially wasting) money investors voluntarily gave them because they think it may lead to a big payoff down the road is capitalism.

Companies doing the "same thing" with government handouts (where the ultimate source of the money had no say in the matter) is not.

It's like the difference between companies that hire workers and those that use slave labor. They may have otherwise identical business models, but the later are operating at an unfair advantage.

sam_goody · 25m ago
The real issue is that we allow patents at all.

Given the lopsided cost that courts bring to the table, patents only help the big players- since only they canafford to play.

I invented something I ttruly think could change the world. Went to a patent attorney. He said basically - create a patent, wait till someone unsuspectingly builds a product with the same basic idea, and then sue the pans off them. If you try to develop it yourself, the patent will not help - the chinese will copy it and laugh, and the americans will copy it, modify it, and then sue you because they can push more patents than you can defend yourself against. In the best case, they may offer to settle for a small fee if you give them all your IP for free...

I have yet to see anything good from patents, but over the years I have seen just how much they prevent anything new from coming to the world.

It's time that prusa gets outside pressure their printers stagnated in innovation and got more expensive. They don't even have machines in the entry/starter category anymore. Why should anyone buy from you if he gets a better experience for less. Especially now that they started to abandon their own core values just have a look at their new offerings they are the opposite for what they plead here. Less open.
cluckindan · 1h ago
That’s a misframing of the situation explained in the post.

Prusa printers stagnated in innovation due to patents filed, making it more difficult to add features. Still, they did expand into SLA and CoreXY.

Prusa printers got more expensive because most of the expensive components come from China, which raised prices and gave subsidies to Chinese manufacturers. That is a de facto export tariff.

They do have entry-level printers, like the Prusa Mini. Of course, it does cost twice that of a Chinese-made clone, but that is because of the aforementioned subsidies.

”Less open” is just plain wrong, almost maliciously so. Prusa offers free printable models of all parts in their entire range of printers. Their firmware is open source, and their PrusaSlicer software is open source. How much more open can you get?

3d printing isn't dead. The policies and programs that encourage it's adoption with lower cost are.

But my bet is on clever people figuring out and systematizing things to reduce the current high cost items.

cameron_b · 1h ago
The article's assertion is specifically "open hardware" 3d printing, facing patent challenges [ other parties patenting designs released as "open" to the community ] especially in China, open hardware designers can't get their work manufactured in China ( in this very example, but similarly in any other country where the patents are filed ) or imported/exported because they become Infringing materials of the patents filed by other parties who have copied their designs.

Open Hardware designers are having to become international patent experts, which is more expensive than releasing the designs to the community for free.

alanbernstein · 1h ago
