Abstract

This research work focused on studying the effect of post-curing on the mechanical properties of stereolithography 3D-printed samples. These samples were subjected to different times of UV post-curing at 37 °C. The IRTF-ATR analysis showed that the UV post-curing acts to break the double bond contained in the acrylic structure of the residual monomers and oligomers and allow them to add to the polymer chains formed during printing and help to create cross-links between these chains. The mechanical performance of the different samples was evaluated using the tensile and impact test, where the results showed that the best mechanical properties were recorded by the samples that were post-cured for 60 min.

UV后固化对光刻3D打印中光聚合物树脂力学性能的影响

本研究主要研究后固化对立体光刻3d打印样品力学性能的影响。这些样品在37°C下进行不同时间的UV后固化。IRTF-ATR分析表明，UV固化后会破坏残留单体和低聚物的丙烯酸结构中的双键，使其加入到印刷过程中形成的聚合物链中，并有助于在这些链之间建立交联。通过拉伸和冲击试验对不同样品的力学性能进行了评价，结果表明，后固化60 min的样品的力学性能最好。
