• Beyond geometric and material limitations
  • Faster and quieter than ever before
  • Even more reliable and accurate


The unique Independent Dual Extruder system allows to print 2 different materials or colours while ensures the finest surface finish. The idle toolhead remains parked, preventing the dripping of molten plastic onto the part.

Multimaterial or Multicolor

Create functional parts by combining the properties of two different materials, like rigid and flexible filaments. Or make your designs more attractive by printing with two colours.

Print further, print soluble supports

Avoid geometric limitations and print the most challenging parts thanks to soluble supports. Just immerse the model into water and watch the supports vanish.


A hotend suitable for each moment: print either the tiniest or the biggest model, use abrasive filaments to materialize your functional part or take the best profit of the IDEX system by combining different nozzle sizes.

Redesigned stepper drivers and improved power management set a new milestone in the accuracy of FFF 3D printers.

With its optimized full metal hotends the Sigma can print any material you need to fit your requirements, from the common PLA to the most advanced technical plastics like Nylon or PC, independently the manufacturer.

As an Open Source project, we share all the designs, manufacturing processes and quality protocols with the Community to speed up the evolution of 3D Printing.

Reengineered cooling strategies allow to keep up the performance while reduce drastically the operating sound. Put a Sigma on your desktop!

Print up to three times faster without giving up quality: finer outlines and coarser infills.

Operate flawlessly the Sigma via its full colour touchscreen. The attractive and intuitive interface is fully equipped with advanced features that guides the user step by step.

The BCN3D Sigma made it to the “Best of Workhorse 3D Printers” in the 3D Hubs 2017 3D Printer Guide, based on more than 8000 reviews from 3D Printer owners: a huge recognition among more than 500 competitors.
