Cosine Additive is a "full stack" hardware/software/data company in the 3D printing industry. Building on its strengths as a hardware manufacturer, the company is developing software tools which, coupled with mass collection of data and machine learning, provide multiples of improvement in the performance and output of 3D printers. In 2015, Cosine launched the world's very first open format industrial class polymer 3D printer, combining professional grade hardware and a free-market approach to printable materials, and decoupling hardware from software. This provides an order of magnitude improvement in cost, speed and versatility compared to similar previously existing machine options. The company is now engaged in three primary lines of business: (1) the design, manufacturing and sale of additive manufacturing hardware and extruders; (2) printing of custom parts (service bureau); and (3) contract research and development in the fields of thermoplastic and thermoset additive manufacturing.
