Mirror Acrylic For Laser Use Info
ARE THERE SPECIAL INSTRUCTIONS FOR USING MIRROR ACRYLIC WITH A LASER?
All of the settings I use with my Glowforge Pro are listed with the product descriptions.
ALWAYS DO A 1" CIRCLE/SQUARE TEST BEFORE STARTING YOUR PROJECT!
1. For the cleanest results, remove the poly film masking (although laser safe) and paper mask both sides.
2. Create your design then “mirror” your artwork. Some laser user interfaces allow you to "mirror"/flip horizontal/reflect your artwork so it may not be necessary to do this part in the design phase.
3. Load material in mirror side down on laser bed & the backside facing up towards the laser head.
4. Select appropriate settings for your laser (I have a GF Pro and use medium red, blue, or black for all of my mirror).
5. Hit that magic button and let ‘er rip!! *PS all mirror is extruded and therefore will have a much stronger smell than the clear/colored cast acrylic
Note #1: For adhesives, you can use e6000, Loctite Go2, 3M double-sided adhesive sheets (SOLD HERE), Super 77 spray, etc. **Never use WeldOn on mirror acrylic because it will melt it.
Note #2: After paper masking the backing, DO NOT try to peel up the paper masking from the edges to "check it" because those are raw blade-cut edges and it will peel away the gray backing before you even get a chance to use the material. The gray backing is what allows the acrylic to be mirrored so you don’t want that coming off. After the cut is complete, THEN you can carefully remove the paper masking from the backside. VOILA!
Note #3: Iridescent acrylic (now discontinued) has a thin plastic protector and this is NOT masking. Be sure to remove this protector from both sides and paper mask both sides. Treat the one side that has the iridescent film on it as the backing when following steps #2 and #3
Note #4: Be sure to test all of your material FIRST! I suggest to run a 1” test square or even a mini version of your project prior to diving into the whole thing. Be mindful that intricate details may not work well when cutting with mirror acrylic so perhaps using a 1" star... or whatever tester size you fill is most appropriate) would be a better test-cut-shape.
Lastly, enjoy your beautiful creation.
