Josef Prusa, CEO of Prusa Research and a long-time advocate for open-source hardware, has announced that “open hardware desktop 3D printing is dead.” He attributes this decline to the rapid rise of China’s 3D printing industry, which benefits from heavy government subsidies and a highly permissive patent system—creating a challenging environment for open innovation, reports Tom’s Hardware.
China designated 3D printing a strategic industry around 2020 and has since supported domestic manufacturers with grants, tax breaks, and subsidized financing, making their production costs substantially lower. Furthermore, the Chinese patent system is being leveraged to hamper open-source designs: companies have been filing inexpensive claims on previously shared open designs and using them to block international competitors. Chinese patents are cheap to acquire—around $125—while challenging them can cost between $12,000 and $75,000.
This has forced Prusa Research to shift away from its open-source roots. Recently, they’ve begun protecting key innovations, such as the proprietary Nextruder used in their Prusa XL, MK4, and Core ONE models. While some parts remain accessible, vital design files are now withheld to safeguard against the complex legal and economic pressures.
China’s subsidized ecosystem and aggressive patent play are undermining the open hardware ethos. For engineers, this signals a shift toward protecting innovation rather than freely sharing it—especially if you’re working with open-source hardware frameworks in desktop 3D printing.
