    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.

    Good news is, you will never be able to stop hobbyist 3d printing.

    Sorry patent trolls, you can’t make aluminum extrusion, stepper motors, an extruder, and a short circuit illegal.

    These patents seam trivial obvious ones. Hope they get knocked down during the case.

      Almost not surprising. Inventors and R&D businesses patent things all the time, then it takes a while to claim them. There was a guy in Australia who apparently invented WiFi (he calls it “wiffey”) and he successfully asserted his patent against WiFi manufacturers worldwide such that they paid him a couple pennies in royalties for every chip manufactured.

      The saving grace is that patents only last for 20 years. After that, anyone can use the design, like Gillette’s double edged safety razor (which is why their modern razors are so silly and change every few years).
