Brick Layers: Stronger 3D Prints TODAY - instead of 2040 (bad patent holding back progress) (youtu.be)

This is about a bad patent that is preventing slicers from making brick-layer prints that would increase strength enormously, despite the fact that there is clear prior art that has expired for nearly a decade. The patent is full of bad references to the prior art and clearly shouldn't have been approved - even if the person saying it isn't a lawyer, it's obvious.

The new bad patent from 2020 would keep the invention away for another 20 years, and do real harm to the development of 3d printing.

The creator asked viewers to share this with people in the FOSS slicer community. I don't know if that's anyone here, but lemmy is pretty FOSS-happy. Also the FOSS communities here might be interested to hear about how this patent is hamstringing development of FOSS features. I don't have the time right now to search through the communities so any crossposts would be welcome.

It's not Stratasys. They did the original patented work in 1996.

This is someone who in 2020, copied the Stratasys patent, submitted it as their own new work, and were granted it!
