3in1out hotend

Anyone have any experience with a 3in1 out printer hotend?
And brand recommendations you have tried?
Was it hard to set up?
Was thier any problems with squeeze out in other tubes?

I know that @jameslancaster has one of those. He brought it to the makerspace once and did some printing. It was pretty interesting.

Yes. I have a Diamond hotend which works pretty well, if you want a particular color, you need to have a purge tower (Or in most cases use infill first.)

Diamond is the original.

Yes, kinda a pain to setup, and slice.

No problem with backflow.

Two ways you can use it, either specifying particular color mixes for a color (so virtual extruders, E0 may be B, E1-Y, E2-R, E3-G, E4-P, and so on.) You kinda need filament that mixes well, and translucent filaments seem to do a lot better. Otherwise, it has some of the same sort of problems of early mixing nozzles, where you can get it kinda looking more like a two-color toothpaste. Or specifying a ratio in the gcode.

Marlin is supposed to have better color mixing now, but I’ve stuck to what’s worked since it’s been a pain.

Setting up models is more complicated. I have generally used Repetier-Host, because it has had the best (but not great) support.) Slic3r I think has gotten better, but I haven’t tried that for it in a while.

It does have limitations like inability to make it lighter/darker, you’d need a 5 color mixer for that. (+White/Black) CMY is recommended. I do find that RGB works. Biggest thing is it depends a ton on the filament if it looks good or bad.


Thx James! Great information.
I appreciate it!
