Penny needed a new tag, so I thought I’d try the Inventables 2 color engraving plastic (1/16 inch). I didn’t get quite where I wanted with this material. I think it might need the enhanced engraving that some of the PRU users had turned on for awhile. Here’s what I got. Don’t care if this group has my number, just don’t sell it to telemarketers. All my disposable income is tied up in the Glowforge and accompanying materials anyway.
EDIT. See @nunzioc s post. He had good luck with removal of the clear film that I left on. Here it is. Still lots of trial and error, but in the end, he got great results with the inventables 2 tone. Made StarWars Coasters with 2 Tone Acrylic - UPDATE: NOW 2 WINS :)
Not good. I used the Inventables numbers and they were WAY too high (although I couldn’t find what watt laser they were referring to). The first one that is not even pictured “engraved” right through the dog’s face and the middle fell out. The ones pictured above weren’t much better.
These are a little better, but still have bleed through. The one at 125 lines/inch definitely shows the line striations close up and still has some color bleed through in the phone numbers. The last one is at 195 lines/inch and the lowest power & highest speed currently available. The lines in the engrave pretty much disappeared, but there was more bleed through.
Here’s a close up of the last one. I don’t think it is pretty enough for my Penny.
Did I mention that this material STINKS when engraved. Possibly because of the over burning, but this was the worst I’ve run into. The Glowforge vents pretty well, but the material smells when you open it to remove it and stays with it for awhile.
So, Here’s my recommendation of you need dog tags:
Anodized Aluminum. Of course you can’t cut these. I bought them online at The Lord of the Rings and they were relatively cheap. You can’t hardly mess them up either. My first engrave was at a very high power and low speed. Not necessary! No photo because it was crooked and I started over. These were done at 100% power and 70 inches/min and 195 lines/inch. Still probably overkill, but didn’t hurt anything. The front took about 3 min and the back about 1 1/2 min. I think I may have saved the front at a higher DPI when bringing it in to the interface? Maybe that is why it took longer.
I’m not sold on 2 color acrylic engraving (yet, fingers crossed for updates). Anodized Aluminum, though, is the Boss. Penny will be proud to wear this new tag.
