Irradiation and Thermal Post-Processing for Vat-Polymerization Additive Manufacturing: Tensile Properties of Four Formlabs Resins

With the introduction and recent advances of additive manufacturing there are a number of materials available for creating medical prototypes. Of particular interest are materials used for imitating bone properties for the execution of mock preparatory surgeries. However, when designing a print for a model it is important to understand the mechanical properties of each material. One of the most common methods of 3d printing is stereolithography. In this paper, four Formlabs resins were tested in tensile loading. Clear, Durable, Tough, and High Temperature resins were used for testing. Samples were tested with and without post-processing curing. Curing was performed in a customized curing oven that follows the Formlabs requirements. After testing, mechanical properties were calculated for all sample groups.
