Photo-Rheology and FTIR Cure Analysis of Photopolymer Resins for Additive Manufacturing
By Nicholas Gripp, Applied Molecules LLC This study undertakes a comprehensive examination of the photopolymerization kinetics of materials commonly used in additive manufacturing, focusing on the discernment of gel point vs. cure point. Leveraging the sensitivity of photo-rheology, 1 the onset of gelation is precisely identified, marking the transition from viscous to elastic … [Read more...] about Photo-Rheology and FTIR Cure Analysis of Photopolymer Resins for Additive Manufacturing
Additive Manufacturing of Novel Surface-Eroding, Non-Swelling Anhydride Resins
Whytneigh R. Duffie; Kevin D. Barz; Tsvetanka S. Filipova; Katrina J. Donovan; Timothy M. Brenza; and Travis W. Walker, South Dakota School of Mines & Technology Several groups have studied the application of water-soluble resin formulations for 3D printing of materials4, with a common concern being the swelling of the polymer matrix during the dissolution process. In this … [Read more...] about Additive Manufacturing of Novel Surface-Eroding, Non-Swelling Anhydride Resins
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
