3-D Printing Materials You Can't Patent

Broad patent claims on materials for 3-D printing may hamper the open-source 3-D printing community's ability to innovate. This algorithm is presented here as a defensive publication of prior art to help identify obvious materials for 3-D printing.

Patent examiners: Following the non-obvious requirement under patent law, claims on 3-D printing materials that can be generated with the algorithm presented below should be denied and existing patents based on materials that can be generated from
