    US9421713B2 - Additive manufacturing method for printing three-dimensional parts with purge towers

    US9592660B2 - Heated build platform and system for three-dimensional printing methods

    US7555357B2 - Method for building three-dimensional objects with extrusion-based layered deposition systems

    US9168698B2 - Three-dimensional printer with force detection

    US10556381B2 - Three-dimensional printer with force detection

    That’s like all of 3d printing, that’s pretty scary. If they win on all 5, seems like it’d kill consumer 3d printing entirely.

      When I look at these patents all of them seem to be patenting others inventions from years ago. So I hope prior art wins.

      Eastern District of Texas is extremely favorable to patent trolls. It’s not a coincidence that they filed the suit there.

      I read the heated bed patent and it was about the way it’s built, so I’m not convinced it’s a general hot bed patent but something more small detail about how they are using it.

      I suspect someone will need to do more research and this article is a knee jerk reaction

      That seems geared only towards FDM printers, so SLA (resin) is still ok-ish? I do suppose those really big powder printers could also suffer.
