3D Printing Custom Colors with Markers?!

Here's one nifty trick big filament doesn't wan't you to know! Unless they sell a sweet transparent filament, that is...
In this video I dove deeper into the technique of using permanent markers to add color to filament before printing, testing various markers, filaments, and machines to see what works and what doesn't.

So who’s gonna put servos on each marker and write software to control the markers going in and out?

You should try using highlighters to see if the end result glows under blacklight.

Aahha yeah I remember that spray paint experiment. IIRC the silver had the same issues with ruining print layer adhesion but (at the time) no other filaments looked like it. I might have to steal the pink black combo it's gorgeous!

Next step: Add small servo motors for automatic color change.

Thanks for doing all of that experimentation! Two things I learned from my own:

1. Using a brown marker (...or multiple markers in different shades of brown) with wood filament will give it pseudo-grain markings. You only want the very tip to touch so as to leave a thin streak, as you *don't* want even coverage. I used this technique to print a plaque as a gift for a friend and it was *very* effective.
2. You can use a jumbo marker and drill a hole through the felt for complete coverage in one shot.

Now Stefan needs to test if those inks+heat don't expel toxic fumes.

You just saved me from giving boring Christmas presents. Thanks 😄

Companies that sell colored filaments:



Stop that right now. We need your money >:(

This got me thinking about what would happen if you used some of those erasable ink pens.

The ink gets invisible with Friction (Heat) but can be visible again if exposed to cold temperature for a time.

I imagine a filament could be designed with this technique in mind. Something that can better absorb the pigment?

Actually, there already are filaments that absorb moisture, like Nylon. Usually that's a bad thing, but I wonder if it makes Nylon a perfect candidate for use with the blender.

What if you designed a custom cap for each Sharpie, or a clip for somewhere on the barrel, that holds a 5-10 gram weight and helps it press harder into the filament without creating too much friction? Might help with colour transfer.

:D thanks for the shout out Devin!!

These experiments are so so awesome! I'm gonna have to try some clear! That black pink is divine!

These are so gorgeous. I love them! 😻😻

I would love to see "mosaic with markers", it could automate color changing :-)

What about highlighter pens? The ink is more translucent and fluorescent and might lead to interesting results.

[ethanm]

Imagine a machine that takes out the sharpies and puts them back in again so you would have the same result as a mosaic pallette, but only with 1 spool of filament and way less expensive stuff. I would buy it any day.

Is it safe to heat sharpie ink at that high of a temp???

[matthewhubka]

Thumbnail is clickbait, I wanted to 3D print in infrared and sharpie doesn’t sell that color

[Noah-ekhp]

MY GOODNESS! This has to be one of the coolest, most creative prints I have seen in such a long time!

[lukeismyname]

I have an ender 5 pro what parts do I need to print for this?
