My first print with Repetier's colour mixing firmware ( http://www.repetier.com/firmware/v092/index.html ) using a Tri-colour

My first print with Repetier’s colour mixing firmware (http://www.repetier.com/firmware/v092/index.html) using a Tri-colour hotend (Tri colour all metal hotend (3d printing head) with single nozzle for a delta printer )

More about the Repetier firmware where one can use up to 16 colours in any combination to print. Colours can be changed in real time with the EEPROM configuration in Repetier-Host or one can have it in the g-code.

Mixing extruder 

Definition
===============

A combination of exactly one nozzle with inputs 2 - 6 filaments driven by
their own filament driver build a mixing extruder. It is not required that this 
combination in deed mixes the colors. It could also be used to put only one
of the colors through the nozzle.

This combination gives us one real extruder that can in theory print many
different color combinations. Through the M163 command, it is possible to
change the mixing ratio at any time. Since slicers do not support this,
the firmware also introduces the concept of virtual extruders. The mixing
extruders can simulate 16 extruders (reachable over T0 until T15) with a preset
mixing ratio. The current mixing ratio can be stored as a virtual extruder
with the M164 command.

I have a few Tri-colour hotends available on my website.

I’m impressed that such a small amount of contact between the cut down MIG tips and the cooling block is enough… And it looks like it works well!
ABS or PLA?

Next step: a model of earth printed in blue+green?

@Electra_Flarefire I am printing with ABS at the moment. Have not tried PLA with the Tri-colour.

Really nice. Can you upload a video showing the printing of one of the bi colored lithophanes you are presenting on your page? Thanks in advance.

@ThantiK why not test ya’ll’s mixing he with this?

@3D-Proto I am not much of a movie maker but will record a video next time I print a lithophane
