Effects of monomer contamination during post-rinsing in vat photopolymerization on dimensional stability.

ABSTRACT: Accuracy is an important parameter of additively manufactured objects. The influence of post-processing on the objects, in particular the effects of monomer contamination in isopropanol used during the post-rinsing of parts produced by vat photopolymerisation, is therefore important. Forty test specimens were fabricated from standard dental resin and divided into four groups, each rinsed with isopropanol containing 0 wt%, 10 wt%, 20 wt% or 30 wt% resin contamination. Optical scans of the specimens were compared with the original design to assess dimensional deviations. The results showed no significant deviations at contamination levels up to 10 wt%. At 20 wt%, deviations were observed in small structures and inclined planes, while 30 wt% contamination resulted in significant deviations in
