Research Confirms Custom-Made Properties for LPBF Steels
Alloys composed specifically for laser powder-bed fusion (LPBF) can lead to optimum production and application-adapted mechanical and microstructural component properties. Unfortunately, selection of LPBF-customized alloys is limited.

To help provide a remedy, researchers from the Chair Digital Additive Production (DAP) and the Steel Institute IEHK at RWTH Aachen University in Germany have taken the approach of adding elementary powders to pre-alloyed, already established powder materials to specifically influence their chemical composition.

High-Performance Vacuum Debind and Sintering Furnaces
Centorr Vacuum Industries is a manufacturer of high performance vacuum debind and sintering furnaces for the 3D Additive Manufacturing furnace market, as well as units for Metal and Ceramic Injection Molding. Available with either metal or graphite hot zones, these units can process all of the most common metals including Fe-Ni, 316-L, 17-4PH, and Inconel powders and feedstocks as well as a variety of other materials including titanium, tungsten carbide, tool steels, and superalloys. The new Sintervac AM™ operates at pressures of 0-15 torr as well as positive pressures of argon, nitrogen, or forming gas for increased flexibility of processing binder-jetted parts, while the Workhorse AM™ is used for the heat treat, annealing, and tempering of laser-sintered parts.

Service Bureau Finds Big Savings in Binder Jetting Vs. Metal Injection Molding
FreeForm Technologies, St. Mary’s, PA, a service bureau for customers across a range of industries, counts itself as an early adopter of metal binder jet additive manufacturing (AM), and also offers fused filament fabrication of metal and plastic parts as well as stereolithography contract-manufacturing services.

Searching for a way around tooling challenges with metal injection molding—lead time, cost and part-design limitations—the firm recently added a Desktop Metal P-1 Production System. By eliminating the need for tooling, the P-1 system has helped FreeForm realize significant cost savings, according to company officials, while dramatically reducing lead times—instead of waiting weeks for tooling, designs can be sent to the printer as soon as they’re completed.

On-demand Webinar Recording: NoSupports Metal Printing
Past methods for supporting metal additive (AM) parts have imposed limitations on part design. The increased complexity of removing supports has added cost and lead time, and some parts & applications have even been disqualified from AM due to support-based issues. Watch now to learn how NoSupports Metal Printing fixes that.
