Since its introduction in 2015, BCN3D's Sigma 3D printer has maintained a steady popularity, positioned comfortably at or near the top of the highest-rated desktop 3D printers list on 3D Hubs since April of last year. At SOLIDWORKS World 2017 yesterday, BCN3D and retailer MatterHackers announced that the Sigma has been revamped and re-engineered as the Sigma R17, now available for presale on MatterHackers' website.
