Discover a new generation of our best-known 3D printer, engineered to grant maximum productivity through a hassle-free experience thanks to features like its massive print volume and full connectivity. Powered by our Independent Dual Extruder (IDEX) system, the Sigma D25 delivers quickly functional prototypes with quality and precision.


Powered by IDEX Technology

  • Developed by BCN3D, the disruptive Independent Dual Extrusion System technology makes the difference in 3D printing.
  • Mirror mode: A mode that enables printing mirrored designs symmetrically and speeds up iteration."
  • Duplication mode: A setting that prints identical models simultaneously, doubling the production capacity.
  • Soluble supports mode: A process that prints soluble parts to create intricate structures and avoid geometric limitations.
  • Multimaterial mode: A technique that makes it possible to print two different materials and combine their properties.


Straight-forward workflow. Wireless printing.

The Sigma D25 is equipped with the latest connectivity features. Easily send your print files when connected to the network for a hassle-free workflow. And forget about manual firmware upgrades thanks to Over The Air (OTA) updates, who will ensure that your printer is always up to date (activated on demand).

An ever-expanding range of professional materials

Work comfortably from your desktop with the most safe-to-print materials, which BCN3D selected for you. The BCN3D Filaments have been developed by renowned chemical companies BASF and Mitsubishi Chemical and optimized to work seamlessly with all BCN3D printers. Ease your workflow with preset configurations and simple commands.



Renovated Design:

Advanced features and increased functionalities

The Sigma D25 is not only different on the outside: our best-known 3D printer has been re-engineered with state-of-the-art features and new functionalities, providing full accessibility for a seamless daily operation.

Surface heating and calibration

Enhanced heat distribution thanks to the aluminum build plate and silicone thermal pad that distribute evenly the heat over the printing surface. The calibration process has also been refined through an optimized firmware calculation system that allows a more accurate adjustment of the levelness

Repositioned extrusion system

The extruders have been repositioned to the back of the printer, reducing the distance to the hotend and preventing overheating issues.

Reinforced axes

Both the X and Z axes have been reinforced. The former through a change of material to stainless steel and the latter through multiple changes in its mechanical structure.
