Topic: Dyeing ABS Plastic

I thought, since I've learned a lot here. I would share the method and results of my experiments. This method should work on most types of ABS plastic, some colored ABS will give different results, compared to natural white. This method also smooths the part. So care must be taken so you don't lose precious, detail in your model. Repeating this method will make the ABS develop more color.
"Warning this method could be hazardous to your health. This should be preformed in a well ventilated area. Wear gloves. Put down paper for any spills. Always wear protection glasses and clothing you don't mind ruining"

"Supplies list"
Protection Gear
Glass Jars - Various sizes
Metal wire
Pliers
Scissors
Colorful Permanent markers "Brand Name"
"not the cheap ones"
Acetone
Distilled water
Optional air pump, for drying
Step 1: Use pliers to remove the tip and break away the body of the marker to get to its core.
Step 2: Cut both up an put in glass jar.
Step 3: Pour Acetone in glass jar.
Step 4: Add distilled water.
Note: Different ratio's of water and acetone will give slower or faster results, when dipping part. A part with a lot of detail will need to be done slowly like 80/20% = water/acetone. All the examples provided are straight acetone and permanent marker.
Step 5: Secure ABS part with wire.
Step 6: Dip the part in solution.
Note: If using straight acetone. Only dip the part for a few seconds at a time and let it evaporate, before you dip it again. Acetone reacts, slowly and for awhile, keep that in mind or you will melt detail from your part. I use a air pump to help dry the part faster. Plus you can dip in other colors without it ruining them.
Step 7: Repeat dipping.
Note: The color gets deeper with more dips.

This method can definitely be improved upon. It's not the best. But some things can't be sanded, primed and painted. For example this method can be used to dye, Super flowers (drooloop flowers) Thingiverse 240158. Below is natural white ABS dyed with red permanent marker.




Different colored permanent markers give different results. Most will remain the same color. For example "Black" when mixed with acetone, dyes white ABS plastic, purple. You can mix the colors. Its kind of like dipping Easter eggs. Below is an example of what happens when you dip in different colors and use an air pump to dry, in between. "The original color was blue"




Note: thin parts become more flexible and are less prone to crack as the acetone melts the layers together and seals in, whatever is in permanent marker.
"A few things I haven't tried yet"
Painting with it - need brushes
Paper towel evaporation method -maybe the permanent marker will get carried in the drops of vapor and be deposited on the model, slowly?
Heating it
Other types of Permanent markers
Better dipping holder - Pin/needle soldered to a piece of wire
Well, that is about it. If I try or remember anything else. I will update this. I hope you all enjoy. And please stay safe, take the necessary, safety precautions if you are going to use this method. I don't want anyone losing and eye or dying of chemical asphyxiation or dyeing their skin a different color or causing an explosion etc... etc...
I use teamviewer to send files to my laptop an print, remotely from my desktop. I also use a webcam to monitor the print when I'm not home using my tablet and teamviewer android app. It allows me to cancel the print in Simplify3D, from anywhere.
