Evaluation of PLA and PETG as 3D-Printed Reference Materials for Compressive Strength Testing

Materials
This study explores the feasibility of using 3D printing technology to fabricate reference materials for validating compressive strength measurements in construction laboratories. Polylactic acid (PLA) and polyethylene terephthalate glycol-modified (PETG) were selected due to their widespread availability and use in fused deposition modeling (FDM).

Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging

Polymer Engineering &Science, EarlyView.
Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.

Mechanical Properties of Additively Manufactured Polymeric Materials—PLA and PETG—For Biomechanical Applications

Polymers
The study presented herein concerns the mechanical properties of two common polymers for potential biomedical applications, PLA and PETG, processed through fused filament fabrication (FFF)—Material Extrusion (ME). For the uniaxial tension tests carried out, two printing orientations—XY (Horizontal, H) and YZ (Vertical, V)—were considered according to ...

Process‐Structure‐Morphing Coupling in Thermally Activated ABS 4D Printing

Polymer Engineering &Science, EarlyView.
Graphical abstract illustrating thermally induced shape morphing in FDM‐printed ABS beams. ABSTRACT Predictable thermally induced morphing in fused deposition modeled thermoplastics remains difficult because the deformation response is highly sensitive to processing and activation conditions.

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...
