Mechanical, Physical, and Wear Properties of 3D Printed Polyactic Acid Materials

Abstract:

The objective of this paper is to study the mechanical, physical, and wear properties of the 3D printed Polylactic acid (PLA) materials. Tensile Strength, Modulus, and Ductility are investigated as a function of the infill percentage and the printing direction. Shioe D hardness versus infill percentage was investigated. Weight loss versus rolling contact time was investigated to measure the wear properties of the parts. The 3D printed parts have shown a great influence by the infill percentage. Such observation was not found in terms of printing direction. The weight loss due to rolling contact was a function of rolling contact time.
