Keystone Industries, a privately held US company founded in 1908, manufactures thousands of dental products as well as its own KeyPrint line of photopolymer 3D printing resins. While the company already works with nearly two dozen 3D printer partners, Keystone faced the challenge of meeting the high-volume throughputs demanded by busy dental labs. Labs make their money by doing the manufacturing for the doctors. While demand for 3D printed dental products continues to surge, the labs are constrained by the size and throughput limitations of their 3D printers. “The simplest solution would seem to be for a growing lab to simply buy more printers,” notes Keystone 3D printing engineer and lab manager Benjamin Taylor. “But that translates into more expense, more maintenance, and the need for more space. The preferred approach is to use faster, larger-volume 3D printers and to keep them constantly pumping out product.”
