This article outlines the essential steps that must be implemented for a laser-based, metal powder-bed fusion process to help ensure that products/components reliably meet specifications.
Additive manufacturing (AM) has evolved from a platform of simple prototypes to the production of mission-critical components for use in high-tech industries such as automotive, aerospace and medical.
Tekna Plasma Systems Inc., a manufacturer of metal powder, will invest up to $128 million over five years to expand its global manufacturing output and boost its innovation capability. The project will help the Sherbrooke, Quebec-based company increase its capacity to over 1,000 tons per year and includes expanding manufacturing floor space, the purchase of production equipment and resources for product development efforts. The investment reflects Tekna’s long-term commitment to the 3D-printing market.
Atlas Pressed Metals started construction on a 45,000-square-foot addition to its powdered-metal-component manufacturing plant in DuBois, Pa. The expansion, which is scheduled to be completed in October, will bring the facility to 100,000 square feet and allow for installation of larger-tonnage presses. Atlas’ on-site powdered-metal capabilities include sinter-hardening, machining, inspection and materials testing.
This article will review areas where the auto industry is already leveraging 3D-printing technology and the role of metal powders and industrial gases in several AM processes that involve laser metal fusion and laser metal deposition.
Braidy Industries finalized its acquisition of 100% of the outstanding equity of MIT-incubated ultrahigh-strength alloy and powder-metallurgy provider Veloxint. The manufacturing base for Veloxint will be co-located with Braidy Industries’ aluminum rolling mill in Ashland, Ky. Veloxint’s research and prototyping facilities will continue to be located in the Boston area and will be expanded in scope.
Metal Powder Products LLC (MPP) acquired NetShape Technologies Inc., a manufacturer and solutions provider of engineered metal components using powdered metal and metal injection molding (MIM) technologies headquartered in Floyds Knobs, Ind. According to MPP, the acquisition creates a global leader in powdered-metal manufacturing and provides MPP with key strategic additions such as MIM capabilities.
Pyro-Paint 634-SIC is an advanced silicon-carbide-filled, water-based coating that significantly reduces the oxidation of most commercial grades of graphite and carbon used in metallurgical applications up to 2550°F (1400°C).
In an effort to expand its capabilities and product offerings, Alpha Sintered Metals acquired Precision Compacted Components of Wilcox and St. Marys, Pa., and Precision Made Products of Brunswick, Ohio, in 2016.
