摘要
为研究紫外光固化三维打印(3DP)的成形技术及成形材料,制备了一种实体材料光敏树脂。使用实时傅立叶红外光固化实验研究了这种实体材料中主要成分在室温和55℃时的光固化速度;考察了黏度、表面张力及工作温度对实体材料可打印性的影响;在喷头为XAAR500的三维打印实验机上,测试了实体材料的打印稳定性和成形精度。结果表明,这种实体材料在55℃时可持续稳定地从喷头喷出,光固化速率和精度符合要求。
To study the technology and materials of 3DP, a kind of model material was prepared for 3DP based on jetting UV curable resin. The photopolymerization velocity of model material was analyzed by Real Time-FT-IR. The influence of viscosity, surface tension, and work temperature was researched on the jetting performance of the UV curable model material. When the photosensitive resin was applied to 3DP experiment machine, the accuracy of model material was measured. The results indicate the resin can be stably emitted from the nozzle, and photopolymerization velocity and accuracy of the resin meet requirement of the 3DP machine.
