Toward a Circular Economy: 3D Printing with Curable Vegetable Oil

Toward a Circular Economy: 3D Printing with Curable Vegetable Oil

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 […]
