The question of when will more engineers use 3D printers may be answered this way—when the price per prototype drops, some say to as far down as less than $1.00 a part. At least that’s what Ezra Zygmuntowicz, CEO, founder, and “hacker” (his words) at Trinity Labs thinks. I met Ezra at the recent MD&M West show in Anaheim, CA. He was displaying his new prosumer 3D printer in the PBC Linear booth. Why there? Because PBC Linear is the supplier of the lead screw rails for the axes and carriage of the Aluminatus TrinityOne 3D printer.
