This Instructables is going to be a work in progress... It's not going to be completed yet, but I wanted to get it started now and I'll work on it over the next couple of weeks to make it a comprehensive Instructable...

Here's a video I made explaining the set-up and how it all works. I'll make a better set of videos that detail everything individually in the near future, but this video should work for now.

So if you are interested in the project - like it, favorite it, save it, then check back in a couple weeks and it should be done...

I did all of this on a Rostock Max that I completely redesigned and rebuilt to utilize the diamond hotend and full color mixing with the new Repetier firmware... I built mine around a delta, however, I want to make this Instructables as universal as possible so you can set it up on any machine you'd like... But I'll mostly be covering deltas because that is what I have/use... But a basic Cartesian FDM printer should be no problem also. (It's actually easier, deltas can be tricky)

Here's what I plan to cover in this comprehensive Instructable

1) Getting the controller board ready for three extruders... I hacked a Rambo board to drive three extruders, however, you can use any board you want... (most people use a rumba due to it having all the pins/components needed for 3 extruders native on the board)

2) Rewriting Repetier firmware to get color mixing working on your machine.

3) How to install, configure, and use the diamond hotend - tips / tricks / lessons learned / etc...

4) My original bowden extruder design and various ways to mount the three extruders for your set-up

5) My universal magnetic effector plate and accompanying hotend mounts for quickly swapping various hotends. (delta specific)

6) How to design multi-color models and making STLs that can be exported and used as a individual STLs or combining them into an AMF file for slicing...

7) Configuring color mixing in Repetier and Slic3r to print above mentioned multi-color models.

8) Anything else I can think of later that I can't think of now.

9) Comprehensive overview of Quantum Mechanical Entanglement as it pertains to multi-color printing (just kidding, I don't understand that shit... But I will cover multi-color printing throughly)

Step 1: Getting everything in order

pretty amazing.<br>I like how you put all the hot ends into one. I only saw them in a separated setup. Is this possible with 5 for a full colored printer or is this to much to rewrite the code?
<p>You can do 5... It's just a lot going on... But wouldn't be difficult... I plan on doing a 5 lead one in the future which will give me white and black... Then I'll truly have full color</p>
I'm going to buy my self a prusa i3, from sunhoky I think. I think I will try your idea after I completely understand how everything is working and I'm getting great quality prints... could take some time but yeah, everyone need a hobby.
<p>im with you :D</p><p>i got a prusia i3 on its way gonna get that running smooth and this will be one of my later mods... this is awesomeness incarnate and will be cheaper then the full cymk(w) one that is out there currently. </p>
Make it 6, and you can have an alpha channel.
<p>Isn't the CMYK color space the one you need to get a full spectrum? That would require 4 leads. Traditional printers use more colors for additional accuracy but 4 looks like the bare minimum.</p>
<p>CMYK - Cyan, Magenta, Yellow, Black - is what works on paper printers... But that only works because it utilizes the white of the paper with the mixing... On a 3d printer, you don't have that so you will need a white feed.</p>
<p>you are absolutely right ... CMYKW to the rescue ;)</p>
<p>Do you have a link to the diamond hotend mount you used in your video? You said that you were planning on putting it on thingiverse?</p>
That is awesome! <br>I came across a printer at geeetech.com, this printer 301, mix with 3 colors, i was wondering if it can also print full color<br> http://www.geeetech.com/geeetech-rostock-301-mix-color-3d-printer-p-1008.html
<p>This is awe-inspiring Jason! You mentioned in your colour mixing video that the people who designed the diamond hotend are considering doing a 5 in 1 hotend? Where did you hear this? I can't find any sources about it online. Also if they don't happen to produce a new nozzle have you considered adding flux capacitors to the three inputs on the diamond to double the amount of filaments you are allowed? it's a project these italian makers are working on http://www.thingiverse.com/thing:301982. You could add PVA in the sixth channel so you can make some awesome prints that require no clean up. I was also wondering what your opinion is on using this setup once black and white are added as a method to do full colour figurines of 3d scanned people. I'm worried that the transitions colours required to do small details like eyes or lips would waste a ton of filament. The other concern would be the difficulty of getting a slicer to read a .fbx or .ply file and then convert it into ratios of how much each extruder needs to push out filament to meet that colour profile.</p>
<p>JJPowelly, </p><p>I am amazed with amount of work you have done with your printers and personal designs! I have a Pursa I3 that I am going to convert the print head to a remote drive like your delta. Could you share the stepper motor drive assembly that you made. I have a MK8 direct drive style extruder and I want to convert it to run a Bowden tube like you did with your drives. I am a little new yet to printing so I hope the above made sense.</p><p> I have found your Thingverse account and I really like all of your night lights too!</p><p>Good work,</p><p>Mark</p>
