Sustainable Raw Materials in Additive Manufacturing
By Corey Long and Clémentine Champagne, Arkema Additive manufacturing generally is considered to be a more environmentally responsible technology by enabling on-demand, local production, with the potential to reduce material waste and minimize the logistic footprint. The key to unlocking its full potential lies in the use of more sustainable raw materials. These innovations … [Read more...] about Sustainable Raw Materials in Additive Manufacturing
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

Conference reviews, developments in materials, print technologies, post-processing, sustainability and other topics of interest will be reviewed in forthcoming issues. The first subject for the column is a review of the Rapid+TCT Conference, organized by the Society of … [Read more...] about Additive Manufacturing Conference Review
Characterizing Accuracy in Photopolymer AM: A Q&A with Michelle Hoffecker and Matthew Panzer from Carbon
Coordinated by Photopolymer Additive Manufacturing Alliance (PAMA)* Members Callie Higgins and Jason Kilgore, NIST Photopolymer additive manufacturing (PAM), or vat photopolymerization (VPP), is a powerful tool that enables three-dimensional (3D), micrometer-level control of the geometric, mechanical and chemical properties of a fabricated part. While useful and potentially … [Read more...] about Characterizing Accuracy in Photopolymer AM: A Q&A with Michelle Hoffecker and Matthew Panzer from Carbon
