While additive manufacturing has been at the center of ART’s business since the beginning, today about half of the end products they produce are not 3D printed, but cast urethane. Casting in urethane has allowed ART to produce low cost plastic parts with a quick turnaround. It is a very hands on process that takes a minimum of 24 hours per mold, requires a significant amount of labor, and the end result is a mold capable of up to 25 parts depending on the material being cast. That said, the effort appears worthwhile based on the high demand from their customers. “Our cast urethane is about 50% of our business right now and we’re almost maxed out,” says Bruce LeMaster, Founder and Vice President of ART. In addition to urethane, ART follows a similar 24 hour process for silicone molding. With such high demand, LeMaster and the team at ART were all but maxed out with a very real cap on the volume of projects they could take on.
