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 ...

Comparing the Applicability of State‐Of‐The‐Art Photopolymer Injection Molds Printed by Multi‐Material Jetting and High‐Performance Digital Light Processing

Polymer Engineering &Science, EarlyView.
The workflow of comparing state‐of‐the‐art photopolymers in rapid tooling. ABSTRACT Additive manufacturing (AM) introduced the concept of layer‐by‐layer manufacturing, which allows the fast and direct production of parts. Additive technologies are also hybridized with conventional polymer processing technologies.

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

Polymer Engineering &Science, EarlyView.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
