The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.
