Printing with different colors

Hi

i’m trying to print a small part in multiple colors
but the more filament changes are necessary the more
i got tired of it. Lot of wasted filament is a second disadvantage.

So my first idea was to glue filaments together but i fear it will stuck up
in the nozzle so i’m currently trying another idea

Printing rods with filament diameter and plug them together

Of course printing this rods takes also time and the way to click them
needs to be improved further. It took the hole day to get a version which fits together
and survives the retraction .

This is the version i have used for the rods above

If anyone knows better way to do it, please let me know

thanks
Johann

I like the effort you put into this but I think the results you will get from that will never really be satisfying.
Take a look at this: richrap.blogspot.ch/2011/06/mult … ament.html Google for similar results.

Thats an interesting approach, though seems a lot work for probably not so impressive results.

What I do is much simpler; I pauze the print, move the extruder, set temperature to 120C. Then I pull out the filament, load new, extrude a bit if needed, reset temp, and resume printing.

In Cura there is even a plugin that lets you insert a pause command at a certain height. Makes it even easier.

Another thing you might want to try is printing nylon. You can color nylon with special dies, and that seems to allow fantastic effects:

I have ordered a spool of nylon to try it out.

Mind you, I would much prefer a dual extruder. Speaking of which, I see there are several dual and even a quad extruder, but what I cant seem to find is a controller that can drive them. What board are people using for these?

hmm, i don’t know yet

think something like a click-together machine would be required

i read somewhere, more extruders more problems - but anyway not in my price class i fear

Definitely this is just experimental and nothing more now …
so have a nice laugh :wink:

I think you got me (or us?) wrong. Nobody is laughing at you! It’s just a very very exotic approach that was never seen (at least from my point of view) on the internet before. Keep in mind that most people would already have failed when creating the SCAD files for your clickable elements :slight_smile:

The new Marlin firmware will come with it’s own hardware (work in progress but almost there) and it has three extruder drivers on board.
I think the current RAMPS that you can get from reprapdiscount or similar provides you with drivers for two extruders.

Starting with small experiments now after further improving the connection
between the rods

Tried green-yellow-green
Seems the rods needs to be longer in the color part because now
i’m using 1/3 connector + 1/3 color + 1/3 connector = 30 mm and
it came our almost only green (with light green)
Also forgot to increase tension on filament at beginning and it wet off :slight_smile:

I will try 10mm+30mm+10mm next to get the different colors better in the print
(and if it works then using more colors)

Nice to see some results!
Did you take a look at the filament fusing method? It really looks a lot more promising.

StickFilament is a new filament, with different colors and materials

Hi Tectu:
Do you know the new Marlin firmware has been pubuliced, dose it can sopport two or more extruders work synchronously? Where can i find the description of the new Marlin firmware?
thanks!
