Abstract Scope |
The effects of natural and artificial aging processes on the mechanical properties of commercially available methacrylate photopolymer parts are explored in this paper. The specimens are produced with GreyPro resin on a FormLabs Form 3L stereolithography (SLA). A design of experiments was developed and the specimens were evaluated for: time elapsed since printing (green, 1 and 3 months), storage condition (ambient laboratory environment, darkened container), and aging process (ambient laboratory lighting, manufacturer suggested post-cure). The mechanical properties were characterized using uniaxial quasi-static tensile and microhardness testing to evaluate the experimental design. Additional microhardness maps were developed through the cross-section of bisected cubes to evaluate the depth-of-cure and spatial gradients due to the aging process. After statistical evaluation, preliminary results highlight the time, storage, and aging sensitivities of SLA-printed methacrylate photopolymer parts’ mechanical properties in both bulk (tensile) and local (microhardness) – discussion on the variance of properties will be discussed. |
