Title: dyeing keycaps using sous vide
Post by: rinkaan on Tue, 07 April 2020, 01:02:07

wondering if anyone actually tried this method?
given the the water circulation would keep the temperature at the required temp for the keycaps, it is only about monitoring the  time to remove it from the  bag...
i dont have a sous vid on hand so wondering if anyone actually tried this method?

Dyeing ABS is problematic because the activation temperature for the dye (175F/80C to 185F/85C) is also the temperature where ABS starts to soften and deform, so bouncing around makes it worse.

Dyeing PBT is easy, I have boiled caps for half an hour with no problem.
