Nowadays, photocurable resin for 3D printing is used in various field. 3D printable dental materials were synthesized by DLP method, which is an advantage of fine-tuning in micro units. Resins for surgical guide need strong compressive strength, wide ranges of workable temperature, low shrinkage. In addition, it is the goal of this 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), and evaluated its compressive and flexural strengths after it was fabricated by 3D printing using DLP method. |
