Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

Polymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

In‐Process Melt Separation of Depolymerized PET in PET/PE Blends for Upcycling via Twin‐Screw Extrusion

Polymer Engineering &Science, EarlyView.
This work aims to depolymerize PET in PET/LLDPE blends via twin‐screw extrusion to allow low‐Mw PET to be extracted and separated. The separated PET is made into BHET and then sold to create virgin PET. LLDPE will be cracked into low‐Mw products that can be utilized as various products.
