5 September 2026GRCop-42 and the Copper Powder Feedstock Problem in Laser Powder Bed Fusion
Copper reflects most near-infrared laser light and conducts absorbed heat away faster than almost any other engineering metal. GRCop-42's move into commercial powder catalogs shows how feedstock morphology, oxide content, and particle size distribution are being engineered around that problem rather than worked around it.

29 August 2026Cold Spray Powder Deposition: Particle Velocity, Oxide Layers, and Why Some Powders Won’t Bond
Cold spray coatings form only when particles clear a critical impact velocity, a threshold set by material properties, particle size and morphology, and native oxide condition. This article looks at what powder-side QC can flag before a spray trial, and where it stops short of predicting deposition efficiency.

8 August 2026Powder Spreading in Powder Bed Fusion: What Recoater Interaction Reveals About Layer Defects
Powder spreading in powder bed fusion is a recoater-powder interaction shaped by cohesion, particle size distribution, and particle shape. This article maps streaking, short-feeding, and layer non-uniformity back to their underlying mechanisms and separates powder-driven causes from blade wear and spreading speed.

1 August 2026Virgin-to-Reused Powder Blend Ratios in Aerospace PBF-LB Qualification: Where the Decision Actually Sits
As aerospace metal additive manufacturing capacity expands, more reused powder is going back into qualified builds. The virgin-to-reused blend ratio decision depends on PSD shift, satellite formation, and morphology drift, and cannot be settled by a single powder check disconnected from the part's stress state.

27 June 2026Copper Powder for Electrification: Why Morphology, Purity, and Packing Density Are Now Engineering Variables
Sintered contacts, additive manufactured heat exchangers, EV motor components, and conductive pastes each require a different copper powder. This article explains why morphology, particle size distribution, oxygen content, and packing density are engineering variables, and how to specify them correctly for electrification applications.
