From the post:

>Parts made using the FFM (FDM) process are stronger in some directions than in others. This is due to imperfect adhesion between printed layers. This directional or anisotropic structural strength is a significant limiting factor for the structural integrity of 3d printed parts made with the common FFM process. A method to drastically reduce this effect is described in an expired Stratasys patent, US1997/5653925A. As of this writing, I have not seen this feature implemented in any of the common open-source slicers. I would have expected this now-public-domain knowledge to have made its way into the slicers we use since the patent expired in 2017.

When digging into this I thought to myself "but you can just print the stuff that way for your own personal use without legal ramifications", then I discovered over there in the u.s. you guys have a more strict patent law that has no personal use exemption for patents. Sad.

Yeah, not only that, this patent should not have been issued in the first place (at least from the little reading I did on it).

I think it is being held back because we can make better shit our selves. We'd be able to make our own businesses making dolls, cars, etc and we wouldn't need AC Delco, Mattel, Hasbro, Tupperware/Rubbermaid and countless other companies that sell cheap plastic shit that has to be replaced because it wore out due to bad design.
