We take it apart so you don’t have to: BCN3D Sigma

The only way to be sure that any machine is really well designed is to take to bits and have a look inside it! That’s what we did at Emvio Engineering with our BCN3D Technologies Sigma! Oh why not check it out in our shop too
Under the beautiful bottom cover of the Sigma we found the electronics and were impressed with the cable management and over all neat setting.


Then it was time to pull the Z axis out for a closer look… The 2 vertical rods are held in place with welded studs on the frame which made the task very easy.

Here is the official maintenance video from BNC3D Techonologies showing how easy it is to remove and replace the hotend
