Lithuanian researchers, in collaboration with 3D Creative Ltd., have developed a universal bio-based resin for optical 3D printing, releasing the details of their study in the recently published “ A Bio-Based Resin for a Multi-Scale Optical 3D Printing .”

In years past, petroleum-based materials have been extremely popular for use in additive manufacturing, but now researchers around the globe have a more definitive focus on renewable sources. Optical 3D printing (O3DP), while generally still used with petroleum-derived resins, offers affordability and efficiency in production, along with a decreased amount of material waste. In this study, the researchers attempted to break free of petroleum products—and the limitations of conventional manufacturing—developing a new resin from soybeans that can be used on the nano- and macro-scale, as well as processed without a photoinitiator. O3DP, accompanied afterward by post-processing in the form of thermal treatment, allows users to create structures and prototypes for […]
