New Developments in Acrylate Oligomers for 3D Printing
James Aerykssen, Dymax Corp.
Abstract:The present work addresses a strong market demand for next generation of oligomers for use in 3D printing rapid manufacturing applications. Printing relatively flexible parts is often challenging for printers that require moving of the parts in x or y direction. Printability versus quick modulus increase during light curing will be discussed. Benefits of new oligomers are investigated in free radical curing acrylate formulations and free radical/cationic curing acrylate/epoxy hybrid formulations. Mechanical and thermal properties of the formulations will be revealed.
