Analysis of the mechanical anisotropy of stereolithographic 3D printed polymer composites

3D printing is a manufacturing technique based on the structuring of parts layer by layer. This principle yields specific direction, that spatial orientation produced layers. Thus, potential anisotropy arising from direction major concern in printing. The mechanical properties biocompatible resin mainly consisting methacrylates and tricalcium phosphate particles examined. Various tests are conducted to examine testing samples manufactured with printer stereolithography. A digital light processing unit (? = 375 nm) utilized produce test three orthogonal directions. Bending behaviour, fracture toughness, hardness measured. Furthermore, microscopy assess fractured qualitatively. Assessed values agreement comparable materials show no statistically significant (p 0.095) evidence anisotropic behaviour. Sample has impact parts. production time capabilities can be optimized varying combining sample without changing performance engineered significantly.
