Effects of UV‐Thermal Exposure Sequence on the Compressive Performance of FDM‐Printed Polymers

Polymer Engineering &Science, EarlyView.
These findings establish aging sequence as a key design parameter for FDM polymers, enabling safer material selection and improved durability of load‐bearing printed components. ABSTRACT Ultraviolet (UV) radiation and elevated temperatures can alter the compressive performance of fused deposition modeled (FDM) polymers, but the combined effects, and ...

Investigation of Crystal Structure Change and Mechanical Properties of 3D Printed PLA After Annealing

Polymer Engineering &Science, EarlyView.
Thermal annealing of FDM‐printed PLA significantly enhances longitudinal tensile and flexural strengths by increasing crystallinity to 46.6%. However, transverse properties remain constrained by weak interlayer adhesion, providing crucial insights into the anisotropic thermo‐mechanical behavior of printed biopolymers for demanding engineering ...
