"3D printing industry veteran Prusa CEO proclaims demise of open-source desktop 3D printing, implicating China as the catalyst of its decline"
In the world of 3D printing, a shift in philosophy and competition is becoming increasingly apparent. This change is most evident in the actions of Prusa Research, a pioneer in the open-source 3D printing movement, and Chinese firms, who are now challenging the status quo.
Recently, Anycubic, a Chinese 3D printer manufacturer, has raised questions about patent legitimacy by selling the Kobra 3 Combo, a printer featuring a multicolor hub that bears a striking resemblance to Prusa Research's MMU system, first released in 2016. Prusa has argued that Chinese firms are effectively locking down technology that was meant to be shared, with the Chinese patent preventing his company from accessing the Chinese market.
Prusa's earlier machines, such as the Original i3, embodied a spirit of community, with components sourced from partners like E3D and Noctua. However, the Nextruder system in the newest Prusa printers, including the MK4 and Core ONE, is fully proprietary, marking a clear retreat from total openness in Prusa's designs.
The open source movement in 3D printing once thrived on shared designs, community projects, and collaboration across borders. But this foundation is eroding due to pressures such as state subsidies, permissive patent rules, and economic support in China. The Chinese government labeled 3D printing a "strategic industry" in 2020, leading to an imbalance in the global competition in desktop 3D printer production. China subsidizes its firms with grants, easier credit, and other economic support, making it much cheaper to manufacture machines there than in Europe or North America.
This price difference has encouraged a surge of local patent filings, often on designs that trace back to open source projects. In China, registering a patent costs as little as $125, while challenging one ranges from $12,000 to $75,000. A bigger risk emerges when agencies like the US Patent Office treat such patents as "prior art," creating hurdles that are expensive and time-consuming to clear.
Meanwhile, there are rising disputes between companies in the 3D printing industry due to these factors in China. Prusa Research, led by Josef Prusa, has announced that open hardware desktop 3D printing is dead. Prusa is not the only company facing challenges; Bambu Lab, another open-source advocate, faces separate legal battles with Stratasys, the American pioneer whose patents once kept 3D printing confined to costly industrial use.
A study from the Rhodium Group describes China's economic support for its firms in the 3D printing industry. Specific Chinese companies using state subsidies and patent-friendly regulations to hinder open hardware 3D printer manufacturing and shift global competition are not explicitly named in the available information. However, it is acknowledged that China invests heavily (over 150 billion USD over 15-20 years) with extensive government support in advanced technologies, creating significant challenges for international competitors in high-tech sectors, which likely includes 3D printing hardware.
As the landscape of 3D printing evolves, it remains to be seen how the industry will adapt to these changes and whether the spirit of open collaboration can be preserved amidst growing competition and shifting regulations.
