The BCN3D Sigma is a professional FFF (Fused Filament Fabrication) 3D printer able to print every object you might set your mind on with very high detail. It is characterized by its IDEX (Independent Dual Extruder) system, which allows to print without geometric limitations and offers the possibility of combining existing techniques such as multimaterial, multicolor and support printing. Independent Dual Extruder - The IDEX system consists in an independent dual extruder, which main advantage lies on its easy calibration and the clean results obtained where combining two colors or materials. This is possible due to each extruder prints each part while the other one remains on the side, preventing the dropping of molten material into the printed part. The independent dual extruder allows the BCN3D Sigma to print multicolored pieces on the same print, taking another huge step in the 3D printing world. This option provides greater complexity to the printed pieces, making them more attractive, without affecting its quality or printing time.
