Dyeing prints with iDye Poly in Isopropyl


#1

Did a few test dyes today on White V4 and Clear V4 with iDye Poly in Red, Black and Green, dissolved in Isopropyl. I ended up leaving them in the solution for around 4hrs. The clear dyed way better than the white, which seemed to be a bit patchy. Would probably be a lot better if the parts were suspended in a jar of the dye rather than sitting in a tray.

Very interesting!

Any changes in properties of the parts after 4 hours in IPA?

Nothing major that I can detect. I accidentally left a large model in IPA over night once and that only softened slightly - nothing gummy or goopy.

I could probably try dyeing them in a water solution, but I’ve found with other plastic dyeing that a solvent works best. It would at least take longer to get the same level of dyeing.

Very cool. I use my rafts for testing finishes and solvents.

fantastic thanks for sharing

Thank you for sharing, especially with the great photos!. This is what this community is about!.


#7

Did you heat up your IPA prior to mixing in the dye? Or was this done at room temperature.


#8

Just room temp. With solvents I’ve found you don’t need/want to heat it up. If you were dyeing in a water solution then I believe it’s recommended to heat it.


#9

Very nice!

When you applied the dyes, were the parts already completely cured, or were the parts dyed, then cured?


#10

This was prior to having a proper curing station so I would say the dyeing was on non-cured parts.


#11

I’m also curious since I’m looking at doing my own experiments.

What ratio did you mix the dye with the ipa? 8 grams iDye per 16 oz IPA (<<< wild guess)? Looking for a starting point.


#12

My ratio was a wild guess. You don’t need much dye though. 8g to 16oz sounds like too much. Start lower (3g?) and see - you can always add more dye to the solution if it doesn’t seem strong enough.


#13

Any idea of penetration of the dye? I need to be able to polish the surfaces and keep the color.


#14

Not too sure on that. Could you polish then dye? Maybe re-polish after the dye if needed. That way you would at least be removing the minimal amount of dyed material.
