BCN3D Sigma 3D Printer

Product ID: 3528


This is quite the snazzy lookin' 3D printer – and it comes all the way from beautiful Barcelona. It's the BCN3D Sigma 3D Printer!

It has a unique, Independent Dual Extruder system that allows you to print two (2!) different materials or colors while ensuring the finest surface finish. The idle toolhead remains parked, preventing the dripping of molten plastic onto the part being printed.

You can print up to three times faster without sacrificing any quality: outlines are finer and infills are coarser. Reengineered cooling strategies allow for maintaining the performance while drastically reducing the operating sound. Additionally, redesigned stepper drivers and improved power management set a new milestone when it comes to the accuracy of FFF 3D printers.

With its optimized full metal hot ends the Sigma can print any material you need to fit your requirements, from the common PLA, ABS, and PVA to the most advanced technical plastics like Nylon or PC.
