Independent Dual Extrusion Printer (IDEX)

The most exciting part of the new BCN Sigma 3D printer is the revolutionary independent dual extrusion system. This IDEX system means that 2 extruder heads on the machine are not joined together but instead operate independently, one head at a time. This unique design allowed us to print and complete the most difficult dual extrusion 3D printed part we have ever encountered (see picture below). Every other machine that we tried this part on failed - the BCN Sigma was the only machine to deliver.

Print with EVERY Material

The BCN Sigma comes standard with 2 all-metal hotends which are capable of printing at up to 280C. That means you are able to print with every 3D printing material including PLA, ABS, HIPS, Nylon, Flexible filaments, metal hybrids, and so many more.

Quick and Painless Setup

Once you open your new BCN Sigma printer you will be up and printing within 10 minutes. There is no assembly necessary with this printer. Additionally, each BCN3D printer is shipped in frustration free packaging to save you even more time.

Untethered Printing

Enjoy untethered printing every day with the BCN Sigma. Each Sigma comes with a built in touch screen LCD which allows you to print all your files using an included SD card.

1 Year Warranty

BCN3D is confident in the quality of their 3D printers which is why they provide an industry leading 1 year warranty.

Seeing is Believing

The BCN Sigma really speaks for itself when you see it in action. Take a look at the video below to learn a little more about the BCN Sigma and its IDEX system.

Comparison between dual extrusion on this printer and UM3? Quality, ease of use, etc?
- asked by Burt on November 1st, 2016 at 10:54a.m.
in the description above under the subtitle 1 year warranty it states the there is in deed a warranty, how ever when I read the section under the terms and use labeled product warranty it states that there is not a 1 year warranty in fact it basically states that there is no warranty that is 1 years length, and no warranty for any non plastic parts. what is up with that?
- asked by Guest on October 11th, 2016 at 2:45p.m.
Any chance it's ever going to be offered in 1.75mm? We have an enormous investment in specialty 1.75mm filament (about $10K), and while I'd love to add one of these to our printer lineup, I can't justify replicating our filament supply in 3mm

what filament can i use on this printer besides the one it comes with. other filaments 3.00mm that i have tried such as color fab seems too thick for extruder. even though there actual thickness is the same as original

Do the fans also cool the parts being printed or are they just for the extruder
- asked by Guest on August 22nd, 2016 at 6:39p.m.
I'm debating on getting this printer or the MakeIT Pro-M. I have a Form2 printer and would like to print using other materials for certain projects. Between the two, which would you recommend? Can't really find much on the Makeit Pro online.
