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!

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.

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

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

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

: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! 😻😻

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

I never comment on videos but feel compelled to with this one! Thank you for making such a comprehensive video showing an awesome technique. I'm new to the 3D printing world but the taste I've had so far let's me know how much time it must have taken to research and test all the various options and tweak all the colors. A video with just the basic technique and a few examples would have been enough but you've gone above and beyond to do lots of that experimenting and documenting for all to see. First video of yours I've ever seen but I'm subscribed already and keen to watch more. Keep up the awesome work!

man the amount of nostalgia i got from watching this video. i haven’t watched one of your videos in like 4 years and you showed up on my recommended. crazy how far you’ve come

I have had my printer operational for a month or less now, and I saw this and knew I had to do it. Finally had some "free" print time and I got a Sharpie holder printed up, and I just love it. I have only done a handful of pieces with this so far, but I've loved every single one and they've definitely gotten better each time. Thank you so much for the suggestion. I will be trying these indefinitely now. I have a specific idea I want to build on too.

Companies that sell colored filaments: Stop that right now. We need your money >:(

11:42, _The color of "Crying Obsidian" in minecraft.._

This is so cool. Can’t wait to see how the concept evolves!

The concept of coloring filament instead of using different filaments is amazing. I never thought of it but now I'm convinced that this is the future. Print heads with built-in ink applicators are bound to happen and just simplify 3d printing to an extreme degree. Clear or white filament could get one almost any color and color could be changed at any step during the print or even continuously. Amazing.

I'd love to see how these blended colors look after surface made smooth with a solvent fog. Great experiments. Thanks!

My mind is just blown away! Damn, I'm so glad I clicked on this video! Thank you very much Davin!

Unbelievable! I have never heard of this method and look forward to trying it out. Thanks so much for letting us know!

Thanks soooo much for this! Printed loads of coloured prints since this came out! This is why i subscribed! (And the puzzles!)

I've been waiting for this since his snapmaker video

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.

brilliant idea Devin. really well done

Hi Devin, I understand absolutely nothing about 3D printing, neither do I own a 3D printer and I don’t have the intention to get one. I just wanted to say that I feel so much comfort by watching your videos... idk how to describe it but something about your personality and the way the video is presented is just so warm and nice and it makes me feel so good. So for that, thank you ❤️

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.

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.

That's incredible. Well executed, so many possibilities. Cheers, JAYTEE

Great technique and well explained. Got me inspired to get out all my old marker and EXPERIMENT! Many Thanks!

I love that this works so well for making colored filament. Especially for colors that you can't buy. I am disapointed that the metallic ones ruined the layer adhesion but hey, you can't have everything I guess.

Way cool! I'm excited to try this with my lighter colored flexible filaments. :)

wow these are beautiful. so cool how much control you can have for surprisingly low expense.

Lol, around a week or two ago we with my friend when working on fixing flash forge printer - did exactly same thing painting PLA filament with permanent marker. And boom, you did a video obout this! Same discovery on different sides of planet! Amazing!

Frickin' SENSATIONAL, Devin!!!!! SEN-SATIONAL!!!

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

I like how you consider your viewers as friends 😊

thank you for sharing this really open my eyes and it so simple too. I'm so going to try this.

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

Few ideas for you: What if you used some alcohol based CYMK ink in tanks. Then run tubes from each color tank to just before the hot end, where the ink is dripped on to a conical rubber wiper that the filament passes through. A felt ring would hold too much ink and reduce the color resolution I think, but that could be another option. The extruder itself seems to mix the colors pretty well. Here are a couple of methods I thought of for physically controlling the inks: a) the tanks could be pressurized with compressed air and controlled by solenoids. b) a peristaltic pump could be used on the output tube of each tank.. Control seems like it would take a lot of trial and error to work out the kinks. OR. What if you designed a bracket for inkjet printer ink cartridges. Modern Ink cartridges include the print head directly in them, so it should be possible to print on to filament with only that. Probably better to pick a cartridge model that has individual color cartridges, so it is simpler to align all the print print heads to the filament. I'm not sure what control signal the cartridges use - it might be easier to hack up an old printer so that you can use its control board too. OR. What if you some how fed Laser printer toner into the heat break. Laser toner works by hot melting around 100C. It may be possible to color filament using that for much more economically than inkjet cartridges.

The ideas are swirling in my head!!!!!

That's an amazing idea! Thanks Devin for the awesome inpiration ;)

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.

Who knew that the nose flute would also work as an additional form of abstinence.

Wow, that looks so beautiful. I was having a conversation about something similar with some friends yesterday. I think the next step is use standard printer techniques onto 3D printers. So having the Cyan, Magenta, Yellow, Black and maybe white ink/pigment cartridges on top of the DD and literally print the colours directly onto the transparent filament before it goes through the hot end. With a bit of technical magic, the potential is full control of colours in every print.

NICE!!! Was about to do a 3 color pause at layer and filament change but was missing one color. Now i will try pause at layer just to change sharpie colors and resume. Thanks for the video im inspired!!

If you ever re-visit this I would be interested to hear how well alcohol ink based pens would work with this technique as well as how nylon works with this technique in general.

So I tried this with oil-based sharpie paint markers, and it works pretty well, one sharpie isn't enough to fully color it, giving you a semi-translucent print and better control over the color blending. It doesn't seem to effect print quality to much either, even the silver sharpies.

Definitely going to try this... Such a cool idea.

I've done this with my printers. I had a couple prints where I wanted to put a stripe in the layer, but didn't want to change out filament. Just held a marker to the filament and it blends fine. Cool adapter you made. Easier than holding it on the spool.

This is fantastic Dave, thank you very much. I have already bought the markers and will test it on my Genius artillery. Being able to automate it would be incredible, hehe. Thanks mate.

9g servos could make this into a cheap multicolour add-on

THAT IS ACTUALLY SO COOL IM DEFINITELY GOING TO TRY THIS

Devon you absolute madlad!! How does this man not have 10 million subs yet?! I absolutely adore the humble genius that is MakeAnything

Imagine making a separate cnc machine that could use certain markers at certain times throughout the print, which is tied to the gcode so that you could have a fully colored print of a model with only a clear filament. No need for multiple heads and filaments.

im a little curious of the lightfastness of this method as sharpies (i believe) are dye based and not pigment based

This is so great Devin! I have an idea to use some servos to precisely control when to apply what colours... I might have to give this a shot!

Ah that is so cool! I saw the marker jig somewhere on Facebook and wondered what it was for.

Is it possible to use this process to get a wood grain effect? I think it would be cool to see a glow in the dark wood grain 3D printed object.

Love this idea. Try 1 silver metallic with 1 blue with translucent filament

This is awesome, definitely gonna try this in the future!

I was very glad to see this video in my feed this morning

Will this attachment work with Ender 3? Looks so much fun, I wish I could design, thanks so much for sharing! Thanks 🙏

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

That is super cool! Well done!

OMG this video cracks me up... Learning about this stuff high... this is perfect.

футболка зачет!

I saw this somewhere. I just didn’t know if it was safe to use with my printer

It's sucks that KZfaq won't let you like a video twice or more!! Thank you for that great video, I downloaded your files and modified it for the Artillery Sidewinder X1. I'll post it on myminifactory and thingyverse soon.

This is so dang cool! Can’t wait to try it!!

Looks like the next step is for it to be automated, like a Mosaic Palette, but with Sharpies

Maybe by using a timer to orchestrate the changing of the pens a uniform colour pattern could be achieved

Stunning results! I love this I will try it in prusa mini

super cool! can't wait to try it 👍

Knitters have long baffled people by making intricate patterns with different colors, now 3D printers are catching up. 😀

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

OMG this is an absolute game changer and I can't wait to try it out!!! Thank you so much for this! I love your Tolstoy War and Peace t-shirt too :-)

i am IN LOVE with this technique. Might become my go to once i start getting into 3d printing. I def wanna look into a way to use liquid ink instead of purchasing many markers lol.

can you try this on a bowden system?

If you stuck an inkjet as close to the printhead as you could get, you could CMY all the filament.

I had to know this couldn't be an idea of mine even tho I had it by myself. I print since less than six months... Well thanks for the journey and the info! I experimented it while tryin a B/W Hueforge painting, The famous Andy Warhol's Marilyn picture. I realized i didn't have as much grey tones as i ned, and saved the day this way. But you already took the discipline to another level, dude! :)

really cool video. i know you said you didnt invent it , but you did introduce me to it, so thank you !!

Have you considered trying this with Prismacolor markers? They're a fair bit more expensive, but the color quality is amazing. Edit: Also...I wonder if you could make this work with Mr. Sketch scented markers.

Could this be damaging to my printer? I would live ri try this great video!!!!!

Very inspiring video! Pink Black is awesome, i might print my 3rd printer build parts in this technique!

Nice idea and explanation!

What only 25k views?!

The mounting pieces seems to be missing in the .zip, only two files in there.

Genius idea and application! Instant sub. Thank you 👍😎🇦🇺

Awesome! I totally wanna try this

Imagine having a third hand

I never understood why the 3d printing companies never made a color 3d printer using ink and colorless filament. It is a "in your face" solution to 3d printing in color. Meanwhile they tried various methods of mixing different color filaments like multiple heads or one head with splicing different filaments. All extremely complex solutions that can only use several separate colours. When you look at a regular paper printer and all the colours it can use - the solution should have been absolutely obvious. Use ink and inject the colours in the molten filament. Have unlimited colors and no extra cleanup block besides your actual print. And yet - nobody ever did it. I don't understand why.

JUST WOW! You sir have earned the subscription support

very cool man thanks for sharing this!!!

Heh... "just scratching the surface of what can be done using this technique"... don't you mean "just marking the surface"? ;P

SOOOO you are making this look like a cool idea but you are really just trying to sell us on buying ink for our printers eh eh?! Didn't we get away from having to buy ink with the lame 2d printers?

I loved your iteration of your original design! I have created a similar upper filament guide mount for my ender 3! The sharpie attachment is removeable so it can be used as a guide with and without the attachment. Great work!

This is too stupid useful. How is this the first time I have seen this. Thanks. I will print one of those 3 sharpie monsters, as soon as my new filament arrives. Oh and now I have to go out and find some colored sharpies. I wonder how the Dollar Tree ones would work...

Like the idea, I am going to try it right now!

Amazing 👌. Thx .I can't wait to get started 💪

Amazing! So next steps: add servo motors to the pen holders so they can be shifted on and off the fillament automatically. That way the color changes can become more smooth and you don't have to sit there doing it manually. The next step after that is add the servo motor's movement to the GCode and have the pens be applied only when coloring specific parts of the print. EG: printing a man, start with a translucent skin tone, tell the GCode to only apply the blue/black pen when printing his pants. Apply red when printing his shirt. Don't apply the pens when printing his hands/face, apply the brown/black/yellow/green(?) when printing his hair. Also so glad you tried the metallic markers I suggested. Thanks for exploring that idea.

I love this idea and I'm going to try it out and I have an idea for a slightly different use!
