For over two decades, 3D printer manufacturer Stratasys has held the patent rights for a relatively simple piece of technology in the 3D printing community.

Owing to three relevant pieces of IP, the company has had exclusive rights to use its own heated build chamber design in its FDM 3D printers since June of 2000. This has meant that manufacturers worldwide have been unable to develop and sell commercial 3D printers with their electronic motion control components isolated from the rest of the build chamber. Naturally, this has made it very difficult to break into the high-temperature industrial FDM market, with companies such as AON3D, INTAMSYS, Roboze, and 3DGence finding novel workarounds.

Of the three patents, US7297304B2 and US20040104515A1 expired back in November 2020. The third and final patent, US6722872B1, is set to expire on the 27th of February 2021 following a previous extension several years before. With the last blockade on its way out, we could very well see a major shift in the way high-temperature FDM 3D printers are produced in the near future.
