- State-backed rivals have made open supply 3D printing practically not possible
- Chinese language subsidies shift world competitors in desktop 3D printer manufacturing
- Low cost Chinese language patents create obstacles far past Europe’s market borders
The open supply motion in 3D printing as soon as thrived on shared designs, neighborhood initiatives, and collaboration throughout borders.
Nonetheless, Josef Prusa, head of Prusa Analysis, has introduced, “open {hardware} desktop 3D printing is useless.”
The comment stands out as a result of his firm lengthy championed open designs, sharing information and improvements with the broader neighborhood.

Financial help and patent challenges
Prusa constructed his early enterprise in a small basement in Prague, packing frames into pizza bins whereas counting on contributions from others who shared his philosophy.
What has modified, he now argues, shouldn’t be shopper demand however the imbalance created when the Chinese language authorities labeled 3D printing a “strategic business” in 2020.
In his weblog publish, Prusa cites a research from the Rhodium Group which describes how China backs its companies with grants, subsidies, and simpler credit score.
This makes it less expensive to fabricate machines there than in Europe or North America.
The problem grows extra sophisticated when taking a look at patents. In China, registering a declare prices as little as $125, whereas difficult one ranges from $12,000 to $75,000.
This hole has inspired a surge of native filings, typically on designs that hint again to open supply initiatives.
Prusa’s earlier machines, such because the Authentic i3, proudly displayed parts from companions like E3D and Noctua, embodying a spirit of neighborhood, however had been additionally simple to repeat, with whole guides showing on-line simply months after launch.
The most recent Prusa printers, together with the MK4 and Core ONE, now limit entry to key digital designs, even whereas providing STL information for printed elements.
The Nextruder system is totally proprietary, marking a transparent retreat from whole openness.
Prusa argues Chinese language companies are successfully locking down know-how the neighborhood meant to share – as whereas a patent in China doesn’t block his firm from promoting in Europe, it prevents entry to the Chinese language market.
A much bigger danger emerges when businesses just like the US Patent Workplace deal with such patents as “prior artwork,” creating hurdles which can be costly and time-consuming to clear.
Prusa cited the case of the Chinese language firm, Anycubic, securing a US patent on a multicolor hub that seems much like the MMU system his firm first launched in 2016.
Years earlier, Bambu Lab launched its A1 sequence, additionally drawing inspiration from the identical idea.
Anycubic now sells the Kobra 3 Combo with this function, elevating questions on how businesses award patents and who holds reputable claims.
In the meantime, Bambu Lab faces separate authorized battles with Stratasys, the American pioneer whose patents as soon as stored 3D printing confined to pricey industrial use.
Declaring the tip of open {hardware} could also be dramatic, however the pressures are actual.
Between state subsidies, permissive patent guidelines, and rising disputes, the inspiration of open collaboration is eroding.
