  • Patent number: 11590706
    Abstract: Methods for post-processing photofabricated articles created via additive fabrication processes are described and claimed herein. Such methods include providing a photofabricated article, preferably an article that has been at least partially cured via cationic polymerization mechanisms, optionally, post-processing the photofabricated article, and base-washing the photofabricated article in an alkaline solution or dispersion to create a neutralized photofabricated article. In another embodiment, the methods include treating a photofabricated article having a residual acid or base species with a treatment composition in order to create a neutralized photofabricated article. Also described and claimed are the neutralized photofabricated articles created via the methods herein elsewhere described. Such articles are preferably biocompatible, especially as determined by their lack of cytotoxicity potential.
