Abstract

Additive Manufacturing is playing a major role in the manufacturing of parts by providing an alternative to the existing processes. However, strength of such 3D-printed parts using specific materials is still an area of current research. Polylactic acid, a biodegradable material, is one of the compatible materials in fused deposition modelling-based 3D printing process. Researchers have primarily focused on testing of PLA material as per ASTM D638 Type I standard. In this research ASTM D638 type IV specimens printed on FDM printer using PLA material are subjected to tensile testing and then compared relatively with the simulated results. Process involves preparation of ASTM specimens in Solidworks software followed by printing using PLA material in a Makerbot 3D printer, conditioning the printed specimens and then subjecting it to tensile testing in AutoGraph AG 15 universal testing machine. CAD model of the test specimens is then subjected to tensile loads in ANSYS software to obtain simulated tensile strength and maximum deformation.
