I am experimenting with some two-color acrylic from inventables. I’ve noticed that there is a fair amount of rub-off residue on these pieces, especially noticeable on the dark colors (ex. yellow on black acrylic).
I hate to think that someone would have one of the acrylic pins that I cut rub off residue on their clothing
What are your best practices for getting rid of this residue?
Thanks in advance!
Best to use some type of masking tape while lasering. And when done, I tend to rinse the piece with or without soap and wipe dry.
Acrylic a nonporous plastic so just wash it with anything that doesn’t damage the acrylic. I’d try dishwashing soap and a soft brush.
As mentioned, masking to prevent the discolor buildup on non engraved areas…
RED (on something) color seemed to be the worst.
I even had to do a very low power additional pass on a few designs to burn off the red residue that blew into the engrave.
I had the issue with black on white 2 color acrylic, and got good results cleaning the engrave with a stream of alcohol from a squirt bottle.
This is a really informative video about two-toned acrylic.
I keep an old toothbrush by the sink, it works great to loosen up those acrylic deposits.
I know, mine does the same. And it’s on the cut edges of my acrylic, even masked on both sides. I let mine cool for 12 hours and I still had residue… If you had any suggestions from trial and error, I’d be grateful!
You don’t need to let it cool, but if you wipe it with a sponge or old toothbrush with some water (soapy if needed) it should wipe off. The residue is just some of the melted/vaporized acrylic from the cut depositing on surfaces, so that’s why the masking ‘protects’ the top, but for the cut surfaces, you’ll just need to wipe it afterwards.
Thank you so much! It did the trick.
