I am looking for a laser-safe material similar to a vinyl that would be sticky on one side. It will be used to cut a matte that will be attached to a glass plate and then sandblasted. The material has to hold up to a bit of sandblasting which will result in the plate being etched in the places not covered by the matte.
I have some VViVid Vinyl but they haven’t been able to tell me whether it is a safe material to laser and I’m risk averse to damaging the Glowforge and killing everyone in the house with poison gas.
Anyone know of a material that might work?
Thanks in advance.
That is viciously expensive. I know someone did this with glass on the forum, hmm who was that.
So I want to use my 'forge to cut stencils that I’d use to sand blast onto glassware. This post is about the sand blasting part of that…
What do I want?! I don’t even know what to look for when purchasing such a thing.
What unit do I want?
What air compressor will I want?
What material would I want to use in it? I’ve read that perhaps silicon carbide is right for etching glass?
I’ven’t a clue here. I’ll say this, I don’t want to spend any real money here. This is a POC/fun thing.
I am looking for a tape that I can mask wood, acrylic and also make stencils for sandblasting glass. Some pieces acrylic that I have don’t have tape on them. I have seen lots of different types of vinyl tapes listed on the forum, but is there “one” that would be good for all the applications? Also, I have read that folks are leaning toward 12" wide tape. I was thinking of 6" wide tape because I would think that the 12" would be hard to work with and it would be more economical since I have …
I mean all I did was search for “glass sandblasting”.
You might have more luck looking than I did.
I bought this stuff…
Turns out that website, while still in existence, is no longer being used! Since it’d been a couple of months since I placed my small testing order, I figured I’d look into it. If it was a scam, I figured, well, it’s “only $30” down the drain. So, I was happy to see they had a phone number. I called and got a live person immediately. A potential win! I explained what’s happening and got a “Oh my goodness. That shouldn’t have happened.” Then he said “Oh! We stopped selling those.…
I’m sad to say I haven’t had opportunity to test it yet. The paper seems like it might be good to use though. But it’s a little more papery and less vinylly than I was looking for. Still, it might just do the job just fine! I really can’t say one way or the other. But worth your time checking it out I’d think.
Rayzist sent me samples when I asked but I have not yet tried them. Assuming it works, I wish there was a place to buy this stuff by the square foot, I just don’t need a $100 roll.
Hmm, here is a hacky idea… Vinyl isn’t safe to cut, but HTV for t-shirts has a similar feel. People have been cutting and engraving things like Siser Easy Weed.
You can separate HTV from the clear carrier. It just peels off. So maybe this would work:
Get your cheapest, thickest, nastiest, stiffest T-shirt HTV
Peel it off the carrier
Adhere the HTV to your glass with something like 3M 77 spray, or maybe Krylon Easy-Tack. Smooth it down well!
Engrave away the HTV
Can you get a good engrave on the HTV, making a clean design?
Evidence on the forum says yes.
Will the HTV stand up to sand blasting?
I have no idea but it would be easy to try with a scrap.
“I mean all I did was search for “glass sandblasting”.”
– Yeah, I honestly deserve to be admonished for that.
Heh, no, not at all, I didn’t mean it that way. I just realized I was parroting the search and that’s not super helpful, I should just tell you how I got there and let you dig in.
