Improvements and main features:

Extrusion system Optimized by E3D.

Hotend manufactured and assembled by the top world hotend manufacturer.

• Finest machining quality.
• Improved thermal dissipation.
• Refined electronics.
• Assembled by E3D

Extrusion by Bondtech

Both R19 printers feature the high-tech dual-drive gears by Bondtech, providing:

• Unmatched grip: The dual-drive gears have ensured a reliable extrusion, getting rid of grinding issues.
• Increased torque: The extruder mechanism reduces under extrusion problems.
• Improved extrusion control: Precise extrusion rate to print complex geometries.

Filament runout sensor

A mechanical switch to detect filament presence allows preventing one of the most common and frustrating failure reasons.

Improvements in the Graphic User Interface.

• Improved information screens
• Maintenance alerts
• More printing parameters to control
• New Assistant to change the Hotend
• Hotend identification
• More materials presets
• Calibration process refined

IDEX System The two independent extruders make it possible to produce with different kinds of materials and colours. Thanks to this mechanism, the properties of various materials can be combined and can complex objects be printed with a lot of detail.

Larger and more complex prints. It is possible now to make figures with horizontally protruding parts or hanging bridges where upholding parts can be printed with a liquid-soluble filament. This leaves no visible uneveness in the printed figure. The Sigma is able to make figures to a size of 210x297x210 mm.

BCN3DNozzle v3 The Sigma has a third generation BCN3DNozzle v3, a fully heated metal head that can reach hours with temperatures up to 280C with peaks of 315C. The print head is standard 0.4 mm and can print a layer with a height of 50 ‘um’. A head of 0.6 mm will be released soon.
