In general, alcohol wipes and acrylic do not play well together, so I would caution about cleaning up the edges in that way.
Some people cut unmasked acrylic with a thin layer of dish soap applied to reduce haze and char from their projects. Others have success with elevating the acrylic pieces off of the honeycomb tray.
There are lots of posts regarding getting clean acrylic cuts here in the forum if you do a quick search.
The Glowforge cuts with heat so “burning” is built in. Most acrylics will not burn, but the “pearl” apparently will. The easiest thing is fine sandpaper or a sharp scraper, but that will also leave a mark but not as noticeable.
You could lower the power and make multiple passes but that may not solve everything.
Yes I use the thick cherry ply setting to cut my acrylic. In the picture you can see the white pearl ,red and copper which have not been cleaned. Just pulled out of gf
Thanks! I tried a couple of variations with sub 200 speed, some with multiple passes and some not; sadly all ended up with smoked edges. I may try again with a higher speed and multiple passes
I took an order for a leather stamp out of Delrin with a lot of small detail that would melt if it got too hot. The fourth try took 20 some passes all near 500 speed and lower power but did finally work .
If you get the stuff with big flakes of glitter, be sure and test first. I purchased some and discovered that the flakes were pretty laser resistant, as well as reflective, so would set the beam of at odd angles melt/burning the plastic as it went.
Indeed. However anything faster required multiple passes and the problem persisted. Lots of trial and error and I’m not sure how much more acrylic I want to waste
Hi @raesumthin , welcome to the community! I hope we can help with this issue. I have a feeling you (and I, since I have the same issue with pearly acrylic from Houston Acrylics) will just have to go to another manufacturer. In the meantime, see if you can salvage the stuff by only using it for applications where the edges will be hidden.
I’ve tried alcohol, ammonia, Goof Off!, and plain old abrasion. None of them are satisfactory.
Take the time to set up @evansd2’s test strip and dial in your settings. It only takes about a 3" by 0.5" smidge of material, and helps you find the perfect settings for YOUR machine and material combo.
