Аналіз термічної усадки полімерів ABS та PLA в технології адитивного виробництва методом FDM

Abstract

Additive manufacturing, particularly Fused Deposition Modeling (FDM), is widely used for rapid prototyping, but ensuring dimensional accuracy and geometric stability remains a challenge. A major cause of defects is the thermal shrinkage of polymer materials, which generates residual stresses leading to warping, delamination, and poor adhesion to the build platform. This study analyzes the mechanisms of thermal deformation during FDM printing and compares the shrinkage behavior of ABS and PLA polymers. Methods for minimizing shrinkage through temperature control and optimization of printing parameters are also systematized.
