  • Copper powder feedstock being loaded into a laser powder bed fusion machine for additive manufacturing

    GRCop-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.

    Cold 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.

    Powder 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.

    Virgin-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.

    Copper 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.
