Improvements of 3D Printed Parts via Bio-Based Modification of Photocurable Resins
By Nathan Noyes and Wouter Vogel, Ph.D., Croda Within polymer-based additive manufacturing, photocurable resin-based processes have gained acceptance due to advantages in printing time, surface finish and interlayer adhesion relative to filament or powder fusion techniques. Still, serial production of functional parts via these 3D printing processes is isolated due to material … [Read more...] about Improvements of 3D Printed Parts via Bio-Based Modification of Photocurable Resins
Challenges for High-Temperature Photopolymers in Additive Manufacturing
By Mehrgan Khavari, 3D Systems Corporation In 2017, 3D Systems’ digital light processing (DLP)-based technology – known as Figure 4® – was introduced. The technology is a derivative of stereolithography (SLA) where a 3D model is sliced into two-dimensional images and the images are sequentially flashed on the bottom of a resin tray equipped with a light-permeable, … [Read more...] about Challenges for High-Temperature Photopolymers in Additive Manufacturing
