Many of us have heard of using vegetable oil for alternative sources of energy like diesel gasoline, but you may be surprised to learn that it can play a role in 3D printing, too.

 .

Previous research has been performed in using vegetable oils with UV curing resins in SLA and DLP 3D printing; however, success has been limited. Authors Yanyan Cui, Junlai Yang, Dehua Lei, and Jiahui Su delve further into the study of alternative materials for 3D printing in the recently published “ 3D Printing of a Dual-Curing Resin with Cationic Curable Vegetable Oil. ”

 .

Dual-curing systems have been known to offer a high curing rate—along with better performance, such as improved mechanical properties and toughness. And, while many photopolymer 3D prints may be the result of dual-curing systems, in this study the researchers focus on the use of bio-based resins for stereolithography (SLA). They combine urethane-modified soybean […]
