Abstract

The study aimed to investigate the selective blue-laser lithography that can fabricate the biomedical materials. The major advantage of using blue-laser instead of UV laser is to lower the machine and operating costs but still keeping the proper part quality for biomedical applications. The material used in the study is the bisphenol a diglycidylether methacrylate (BisGMA) which is specific formulated for photo-polymerizing with blue laser (wavelength = 473nm). The fabricated parts were preliminarily examined by flexural strength testing and in vitro testing of toxicity by direct contact test. The results showed that the flexural strength of fabricated part was about 92% as compared to the flexural strength of hand-pressed PMMA. The in vitro testing of toxicity, confirmed that the fabricated part by the selective blue-laser lithography with BisGMA material has good biocompatibility.
