The wall sign went over so well at my Friend Soo’s restaurant Kenzo, I decided that the metal M & W on the restroom from Home Depot was not going to cut it… so fired up “Phasers On Stun” and cranked these out.
I used the Two-Color Acrylic from Inventables… to be honest, its sort of a pain to Laser, I played with a piece of scrap for several hours trying different settings, no matter what I tried there was always a red residue on the white. I ended up spending about an hour on each with an Exacto Knife scraping out all of the melted Red residues. I ended up with 15% power, 300 Speed, 340 LPI and 3 passes to get the cleanest I could get but it still required elbow grease.
In the future I will cut the design on 1/16th Acrylic then just weld it to another bottom sheet of a different color… way cleaner.
In the end, I think I came out great… she is going to LOVE IT!
I talked to Inventables they said for some reason the Red is a little tougher to work with than the other colors especially Red on White. Let me know if you find settings that work a little better for you.
You might want to do a forum search on cleaning up that two tone stuff. I seem to remember a few months back that somebody had figured out an easy way to do it. I’m thinking it was an alcohol wash or something like that.
Thanks @cynd11, I did try the Alcohol wash but I think in reading that it was more to remove the protective plastic residue. It did help a bit but in the end, I had to scratch it off. If anyone has any better luck I’d love to hear it.
