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 picked up some of that two-tone stuff…haven’t figured out what to make with it yet.)
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.
Came out great!
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.
They came out amazing, your effort and perseverance really paid off! Those circles are so organic it looks like leather.
That looks awesome! You’re not alone in your 2 color frustrations, and this is a great solution - much faster than engraving, too.
