Two color 3D printing with single extruder and manual filament changes

Manual two color 3D printing in same layer with one nozzle and one extruder is possible, not easy, but possible. Don't mix this method with simple color change on certain layer and everything in that layer will be printed in same color. This method can be used for color printing in vertical or curved surfaces too. In this process I am explaining the design, slicing and 3D printing. First two printings are not perfect, only in last object (mini cube) I show the final settings which worked for me.
All STL files used in this video can be downloaded from my website:

Download them and start experimenting. If you find better settings, please, let me know.

I have to compliment you on your persistence and patience. Great experimentation and problem solving. Thank you.

[@nacs]

Nice. I'm going to try this on my Ender. thanks for showing the whole process

[@mihaicristian4079]

Those prints come out very cool! Thanks a lot for this well explained tutorial!

[@logothaironsides2942]

Fantastic. You have done the hard work for us. Much appreciated.

[@vynaltheworld4092]

omg this is so amazing and this is what I've been looking for for about a week and I was looking for one that uses prusa hardware

[@dungeonsdragonsderrick8029]

Thanks so much for this! Really helped me out with this whole process!

[@avejst]

Thanks for sharing
Great intro to multicolor in Pruca Slicer :-)

[@christeschke9844]

very good job. seems very interesting.

[@TheSmokintbird]

Wow, HARD mode two color prints!

[@dmddmd2904]

Спасибо. Интересный метод.

[@DadicekCz]

Cool!

[@SianaGearz]

Haaa, i can make MX mechanical keyboard keycaps with embedded graphic or lettering this way. Useful!

[@MyTechFun]

Best results I god with up-side down, color change in first layer on textured sheet, like box in this video (only the I+V letters, but that black date inside doesn't look so good) th-cam.com/video/OBxocd2nDR0/w-d-xo.html

Think I will try this method with a "wipe" instruction after every tool change.

Hi. I have flsun SR. Flsun SR is not in Průša slicer, but I want printing multicolour. Can I do it in Cura slicer?

[@burtjoubert]

Did you figure out a way to stop the "filament change" after the initial primer line is printed? Mine keeps doing what yours did in your video. I load the first filament, then it starts and primes the line, then immediately asks for a filament change...Any idea how to fix this?

[@MyTechFun]

When I generate G-code, I open it with Notepad and delete the first M600 command.

[@burtjoubert]

@@MyTechFun Thanks! Any way to change the default values in Prusaslicer directly so I don't have to edit the G-code every time?

[@pascal5530]

Just add this to "Tool change G-code" under "Printer settings" -> "Custom G-code":
{if previous_extruder == -1}
; we want to supress the first unnecessary M600
{else}
M600
{endif}
At the beginning of the print the previous_extruder is not set yet, so we can just check for it and only add the M600 for all other extruders. Works like a charm 🙂

[@michaelharto2285]

Hey, i have a problem with extra extrusion after filament change like in the video, do you have any solutions for it

[@MyTechFun]

Same printer and slicer? (Prusa) My final settings are from 21:24 th-cam.com/video/W3z_b52lSIA/w-d-xo.html

[@BirchNirga]

Is there a setting to tell you which color to load into the printer? I am trying to print 3 colors but cant tell which color I am supposed to load in

[@MyTechFun]

This depend of the printer. I tried some notification g-code commands, they didn't work with that version of firmware on Prusa MK3. Since that I didn't tried 3 color printing (only 2). Try to add 1, 2 or 3 beep sounds before color change (depend of the color).

[@BirchNirga]

@@MyTechFun I made a custom code that parses gcode files and tells you which extruder you are supposed to change to. I put it on the pruss forum if you want to see
