on 02025-05-28#video by #Titans-of-CNC on #3D-printing with #binder-jetting, profiling a job-shop company in Ann Arbor named Azoth Digital Metal (Azoth being the alchemical universal solvent). The Markforged “PX-1 odger” (?) printer they like most can do up to 90kg in a single run, using 70400 nozzles each depositing 2.1 picoliters of binder at 15.5kHz, using air bearings and linear motors, as explained by Markforged’s bizdev manager for metal binder jetting, Ross Adams. Markforged’s technical director Hans Kimblad was also for some reason onsite, and also their president and CEO, Shai Terem. They’re printing small parts like firearm mag[azine?] releases, saying it’s much cheaper than machining but more expensive than metal injection molding. They’re also 3-D printing seatbelt parts that then get chrome-plated. They say they can hold tolerances of “plus or minus about three thou” on small features, ±75μm, “five thou would be typical”, and presumably even worse for large features: “I give people a 1% rule,” so a 400mm dimension would be ±4mm! “It’s a small complex metal part technology. So really I’m focused on parts 120mm in the longest direction, or smaller.”
