Assessing the Impact of Top-Up Powder Reuse Strategy on MS1 Powder Characteristics and L-PBF Printed Part Properties

Metals
In additive manufacturing, particularly with Laser–Powder-Bed Fusion (L-PBF), augmenting recycled powder with virgin powder is common to extend lifespan. This practice complicates tracking recycling cycles, as parts consist of layers from both virgin and

New powder reuse schema in laser-based powder bed fusion of polymers

Waste Management
The laser-based powder bed fusion of polymers (PBF-LB/P) process often utilizes a blend of powders with varying degrees of degradation. Specifically, for polyamide 12, the traditional reuse schema involves mixing post-processed powder with virgin powder at a predetermined ratio before reintroducing it to the process.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
