We are a bunch of passionate additive manufacturing practitioners comprised of veterans and new comers alike that are determined to break the speed, productivity and performance barriers so that our industrial and medical customers can harness the full potential of AM for same-day prototyping and series production. We developed two groundbreaking technologies that improve polymer additive manufacturing productivity by orders of magnitude. Our photoplastic printers are powered by our Lubricant Sublayer Photo-curing (LSPc)  technology and our thermoplastic printers are powered by our Quantum Laser Sinter (QLS) technology.  Our fourth-generation SLA and SLS printers use higher performance photopolymers and supply chain approved powders that together with validated workflows and software tools drastically reducing 3D printing cycles of functional parts from hours to minutes. We exist for the sole purpose of serving our customer’s industrial and medical polymer production needs through greater design agility and supply chain resiliency.
