Possible infringement of Stratasys patents #12

Closed milkey-mouse closed 5 years ago

milkey-mouse commented 5 years ago

I'm not a lawyer, but the main reason I didn't experiment with infinite-volume/belt-based 3D printers before was Stratasys patents US8282380 & US8287794.

You have probably encountered these before, but is there a consensus, or hope, that these patents don't cover a printer with a slanted Z axis like this one?

This may be a potential barrier to commercialization (and I wouldn't put it past Stratasys's lawyers to go after individuals, either).

I designed this mechanism specifically to get around their patents. In both patents, claim one fails this kinematic model because we are not positioning the extruder in the XYZ space... All the rest of the claims are dependent claims, so they do not apply.

Thanks Bill.. I'm assuming my design is within the same constraints as yours..

wjsteele commented 5 years ago

Yes, it definitely is.
