Nowadays, photocurable resin for 3D printing is used in various field. We synthesized materials for dental materials that can be printed with a 3D printer. And we use the DLP method, which is an advantage of fine-tuning in micro units. Various materials used for dental materials have different properties depending on the application. Resins for surgical guide need strong compressive strength, wide range of workable temperature, small shrinkage. In addition, it is the goal of the research to make environmentally friendly materials with biodegradability because they are made customized for patients, used for surgery or disposable during surgery and discarded. In this study, in order to get better chemical and mechanical properties, polycaprolactone, aliphatic polyester, was used to synthesize photocurable 3D printable oligomers with methacryloyl chloride, and hybridized with silica nanoparticles, which was surface modified with vinyl-trimethoxysilane (VTMS). |
