The Sapphire system utilizes a technology the company calls Intelligent Fusion. The system is capable of 3D printing complex metal objects by sintering a bed of powder with a laser, in a process similar to standard resin-based 3D printing systems.
One of the more compelling aspects of the technology is its ability to create geometrically complicated objects without the need for the support structure most require. Rather, the objects, as described by Chief Product Officer Stefan Zschiegner , essentially come out of the out of the powder fully formed.
Among the things that set the company’s new machine apart from some of the competition is a focus on additive manufacturing for production, in addition to prototyping.
