Soooo, picked up a couple of two tone acrylics from Inventables…
@dan: You guys really need to offer these in PG; so cool!
Anyway, even though the plastic protective sheet says to leave in place when “laser profiling”, I peeled it away and did a test on the black on white, and it came out pretty nice (although with ridges, but the site states “Note: PPI’s over 400 when used in vector cutting are likely to cause of tacky edges”)…but with lots of residue that I had to clean up with lighter fluid and paper towel scrubbing:
Once cleaned, they look pretty nice! Still some black on white, but I think more scrubbing with lighter fluid, and a toothbrush, would clean it even more:
Diameter is a little under 3 inches, print time was 1.5 hours.
Sooo, I figured let me keep the plastic coating on for the next print, since taking it off left so much residue. Big mistake!
As you can see, there are a lot of white clumps that seem to have melted and re-solidified. They are solid, and tough; can’t even scrape away with a razor blade scraper. I’m guessing the clear plastic coating melted (instead of vaporized), and the white got captured up in it, and made the clumps.
From the materials page, it also says they recommend leaving on the plastic when making vector cuts. I guess not recommended with raster cuts.
I called the inventibles support line, and the rep was really nice but not sure if leaving the plastic on caused this, so she said I should send them an e-mail and include pics, and she’ll get it to people there who are more familiar.
Btw, as other have noticed, this leaves SO MUCH dust in the forge!
Width & height are both a little under 3 inches, print time was also 1.5 hours.
Oh, and I’m going to see how a 2nd pass on these does; maybe I can fix it without ordering another sheet…
Wish me luck!
