CUBETRIX IDEX ( DIY Sigma BCN3D Style 3D printer )


As you well know Sigma/Sigmax BCN3D are one of the best 3d printers with IDEX system (dual independent x axis) and since they came on the market I always wanted to have one. Knowing the price I decided to build one that had the same characteristics or even improve some features. I have named this CUBETRIX IDEX printer.

Current printer characteristics:

The innovative Independent Double Extruder (IDEX) system allows two different materials or colors to be printed. The idle head remains inactive, thus preventing the dripping of molten plastic on the piece being printed.

Simple mode:

Print with a single head either on the right or on the left

Duplication mode:

Print the same model with both heads simultaneously, doubling the productive capacity.

Mirror mode:

Prints the model and its symmetric part at the same time, increasing the speed of iteration and reducing design times.

Mode 2 colors/filaments:

Print alternating 2 colors or using a head to build the piece and the other head to create the supports with soluble filament or just usual filament.

Printing options:

Usb connection, wifi connection (acquiring wifi module), from a usb pendrive, from a SD card.

Touchscreen LCD (3.5 inches): print your projects with the touch of your finger or simply configure your printer from the LCD.

BondTech redesigned body system extruders ( right and left extruder ).

Bowden extrusion system with E3D hotend  ( CR10 model )

MGN12H Linear rails on all axis.

Printing area: single mode 330x330x250mm, mirror/duplication or 2 colors mode 160x330x250mm

Bltouch autolevel system

Heated bed : aluminum heated bed or silicone heating pad (your choise)

OPEN SOURCE (Marlin firmware and lcd firmware):

As you already know from other projects of mine, I'm feeding from the OPEN SOURCE movement like a lot of people and, in exchange, I offer my projects for free, so that this OPEN SOURCE movement can continue to exist and advance making people more creative.

Simplify3D profiles:

I have provided Simplify3D profiles for this printer so that you do not waste time in setting up the printer and in that way you have all the pieces of this puzzle.
