Influence of Annealing Temperature on the Thermomechanical Properties and Dimensional Stability of FFF‐Printed PET‐CF

Journal of Applied Polymer Science, EarlyView.
Following extrusion at 265°C, components underwent a 45‐min annealing process at temperatures from 145°C to 225°C. The results show that increasing the annealing temperature elevates the onset of thermal softening, significantly enhancing thermal reliability.

Analysis of the Elastic Behavior of Selected Types of Plastic Materials Used in 3D Printing

Macromolecular Symposia, EarlyView.
ABSTRACT This article analyzes the elastic behavior of 3D printed plastic materials, using FDM technology, to understand how they react to mechanical compressive stresses and to determine the limits of reversible deformation. In this research, a series of compression tests were performed on specimens made of five types of plastics: ABS (acrylonitrile ...
