BCN3D Technologies releases open source files for BCN3D Sigma 3D printer

Barcelona based 3D printer developer BCN3D Technologies decided to further embrace the additive manufacturing open-source philosophy with their latest initiative, Open Source 360º. As part of the initiative, the company has announced that it will share all of its engineering, design, and fabrication information used in the manufacturing of their flagship product, the BCN3D Sigma 3D printer.

The BCN3D Sigma 3D printer, for its part, is perhaps one of the most well-regarded dual-extrusion, professional grade desktop 3D printers on the market. The printer, which costs $2,540, boasts a build volume of 21 x 29.7 x 21cm with a resolution of 50 microns maximum. The printer has offered makers an Independent Dual Extruder system, which allows for easy calibration and virtually limitless geometries.


The easily accessible information, hosted through BCN3D Technology’s website, is divided into five levels: software, hardware, process, tooling, and teaching. In a press release, the company explains that in the software level, the documents will go through the BCN3D Sigma’s firmware (Marlin’s Evolution), source code, and the BCN3D Cura. For its hardware, users will be able to browse and see every detail of the Sigma’s mechanical design, including 3D files, 2D drawings, and assembly instructions.
