Printing Solid, Simple Metal Parts in Minutes, Spee3D Process Is Competition for Casting
Kennedy is the co-founder and CEO of Spee3D
The company’s technology is based on a mechanism long used by the U.S. military for manual repair, with the metal spray directed by hand. Figuring out how to translate CAD files into programmed movement for the seven-axis robot manipulating a flat build surface around the stationary nozzle was perhaps the biggest challenge of developing this machine. But accomplishing this resulted in a method of building metal 3D parts that is fast relative to other AM processes—100 to 1,000 times the deposition rate of powder-bed machines, Kennedy says.
The resulting parts look and function much like castings. He sees casting, not other metal AM systems, as his chief competition. With the ability to produce solid forms six or eight inches in their longest dimension within a build time of 10 or 15 minutes, he says that “in the time it takes you to ask for a quote on a casting, we can print one.”
