Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

open access: yesPolymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.

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

open access: yesPolymer 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

open access: yesPolymer 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.

Experimental and Numerical Thermo‐Mechanical Characterization of Polylactic Acid Fabricated by Fused Filament Fabrication

open access: yesPolymer Engineering &Science, EarlyView.
Experimental and numerical framework for characterizing the thermomechanical response of polylactic acid fabricated by fused filament fabrication. ABSTRACT This study investigates the thermomechanical response of polylactic acid (PLA) specimens fabricated by fused filament fabrication (FFF) at two nozzle temperatures (190°C and 230°C), while mechanical
