Additive manufacturing, commonly known as 3D printing, revolutionizes the realization of computer-aided designs (CAD) by layer-by-layer printing of prototypes or objects, emulating traditional modeling techniques. Also, according to ASTM standards, additively manufactured prototypes using plastics must undergo the tensile strength testing using the ASTM D638 - 14 Standard Test Method for Tensile Properties of Plastics. The objective was to fabricate and analyze the effects of different geometries on the mechanical properties of the produced meshes. I also determined the differences in mechanical properties when it comes to materials used in printing. Three different geometries (simple grid with holes, hexagonal grid, and zig-zag patterns) were printed using five different photopolymer resin types, and their tensile modulus (Young's Modulus, YM, of Elasticity) and tensile strength were examined using a mechanical strength analyzer. Simple grid with holes (Mean YM ≈ 1.255 MPa) showed higher strength whilst the hexagonal grid pattern showed the least strength mechanically (Mean YM ≈ 0.346 MPa) Translucent photopolymer resin with average YM of 0.0.231 MPa had the highest level of flexibility but less strength. This research contributes to a deeper understanding of how geometric design and resin characteristics impact the mechanical performance of 3D-printed prototypes. By showing these relationships, this study provides valuable insights for optimizing material selection and geometric design to meet specific application needs, ultimately advancing the field of additive manufacturing.
