Abstract

This present study investigated how heat treatment affects the mechanical properties of 3D-printed PLA+ by manipulating two parameters: heating temperature and holding time. The mechanical properties of 3D-printed PLA+ components are crucial for assessing their structural integrity and performance. Annealing can improve the internal structure and mechanical characteristics of 3D-printed objects made from PLA+. Heat treatment is an appropriate method to remove the porosity defect because the air gaps in the material are filled with itself when it melts at high temperatures during this process. The research explores changes in flexural strength, creep resistance, tensile and compressive strength before and after subjecting PLA+ samples to controlled annealing conditions. The findings aim to enhance the understanding of heat treatment as a method to improve the performance of 3D-printed PLA+ components.
