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 ...

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 ...
