Hi,   I own a BCN3D Sigma dual extruder and I am relatively happy with Esun PVA as a support material.   I have also been printing with Scaffold by e3D, wich is a PVA modified, and performs better, but still have issues in terms of moisture and material adhesion.  
Hi everyone,   I am looking for a good 3d printer, and is interested in Ultimaker 3 Extended and BCN3D Sigma. Looks like they have similar features such as dual extruders. Can someone tell me which one is a better choice? Price is not a major concern here, just need to find a better one in terms of function / power. Thanks!

Hi, 3D-printing lovers! I know, Christmass is not a good time to introduce something, but I'm so excited about my new doll Dory!   */ She is a fully 3D printed doll, including the hair, wings, shoes and dress. She is 16cm (6’) tall and has articulated neck, chest, shoulder, elbows, wrists, hips, knees and ankles. The parts of body are stringed with an elastic. */
I'm just starting to instal my new BCN3D Sigma. I tried to load the filament starting with the left extruder. It succeded but it was pretty slow. When came the time for the Right extruder, the filament just didn't wan't to get stuck in the motor to get pulled. I don't wanna force the motor so what can I do?  Thanks,Alex
  Hello fellow Hubs,    Another year, an even bigger guide. This year 8,624 reviews, 915 hours of writing, 4,982 years of experience and 1.14 million 3D prints led to the 2017 3D Printer Guide. A big thank you is in order to all of you that helped make the guide possible again - your Hub badges will go live today!  
A professional FDM printer with dual extruders, large 21 x 29.7 x 21 cm build volume and 50 micron maximum resolution. Its main differentiator is the Independent Dual Extruder system, which allows users to print without geometric limitations using dissolvable support materials (PVA, HIPS) and to combine various materials for multimaterial and multicolor printing.
Hello,   i want to sell my BCN3D Sigma. I bought it 2 months ago and I'm very satisfied with the machine and the results. It has full guarantee and is in a very good condition. I sell it because I didn't use it that much and have to focus on my "normal" job ;-)   I will post some pictures and details later.   If you are interested you can PM me.   Best Regards.Sedat
great team at bnc3d technologies, good catalog of machines made in spain, improving everytime, in my case, my machine a sigma an absolute beast that eats nearly any filament, what is not still done will be done like reaching the perfect matirials and their way of working,  i mean the catalog of filaments keep raising as they appear...as i said this machine eats nearly every  filament
Hi All.   This may be a daft post..   In order to print parts faster, is it simply a matter of increasing the print speed? or does other factors you need to considered. I've read somewhere regarding flow rate etc. but I'm not 100% sure. I know decreasing the Z resolution and infill % helps but are there any other tweaks to consider.   Thanks
