Abstract

Photopolymerizing 3D printing methods such as Digital Light Processing (DLP) enable high-resolution printing. Poly (ethylene glycol) diacrylate (PEGDA)-based material systems are interesting for biomedical as well as tissue engineering applications. For DLP based 3D printing the material systems need a photoinitiator as well as a light absorber for adequate printing performance. LAP (photoinitiator) and Orange G dye (light absorber) are promising additives to be used for biocompatible, photopolymerizable material compositions to be processed at a wavelength of 405 nm. Here we investigate the dimensional accuracy of DLP printed parts using PEGDA compositions with low concentrations of LAP and Orange G.
