The BCN3D Sigma R17 is a professional dual extruder 3D printer, voted Best 3D printer Workhorse 2017 by 3DHubs users due to its great performance, innovative technology and build quality.


BCN3D Sigma professional desktop 3D printer with dual extruder


The BCN3D Sigma is built with an innovative independent dual extruder system so you can print with two different materials, or in two different colours, whilst maintaining a high quality surface finish. The idle printhead in this dual extruder 3D printer remains parked to stop it from dripping molten filament onto your 3D print.


bcn3d sigma dual extruder 3d printer allows you to 3D print complex models using soluble support material


Buying a dual extrusion 3d printer is not just about printing attractive two tone prints, where it comes into its own is when you combine two different materials in one print. This is especially true when you make use of a soluble support filament like HIPS (for ABS) or a water soluble PVA filament. If you use a soluble support filament as infill this allows you to make very complex parts that would not be possible with a single extruder 3D printer. A dual extruder 3D printer therefore opens up the possibility for 3D printing functional parts.


Avoid geometric limitations and print the most challenging parts thanks to soluble supports.

The Sigma R17 3D printer features

So additional to the Sigma R17’s dual extruder technology it also employs the IDEX hotend system. The IDEX system is a series of swappable hotends with different nozzle diameters and nozzle characteristics. This means you can select the right hotend for the job, saving both time and money, making your 3D printing workflow more efficient. For example you can print your perimeters with a 0.3mm hotend and the infill with a 0.8mm hotend, or, print your model with 0.8mm and detailed PVA supports with 0.4mm.

BCN3D Sigma R17 3D printer uses the IDEX system fo swappable hotends to improve 3D printing efficiency

BCN3D Sigma IDEX hotends come in:

  • 0.3mm

  • 0.4mm

  • 0.5mm - Hardened Stainless Steel, ideal for carbon fibre filament like ColorFabb XT CF-20

  • 0.6mm

  • 0.8mm

  • 1.0mm

BCN3D hotends are available as either the Idex Hotend Family Pack or buy your BCNozzle Hotend separately. Or follow the link for a full listing of our BCN3D 3D printer products.

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

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

The Sigma has a top grade build quality. The Sigma R17  boasts Re-engineered cooling strategies to give high performance whilst drastically reducing the operating sound. Also the redesigned stepper drivers with improved power management set a new milestone in the accuracy of FDM 3D printers.

With the BCN3D Sigma full colour touchscreen you get an attractive and intuitive interface that is fully equipped with advanced features that guides the user step by step.

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.

the BCN3d Sigma 3D printer awarded 3D hubs best workhorse 3d printer for 2017

But, don’t just take our word for it. 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.
