I thought the same thing. But according to the description, it’s non combustible paper.
While masking is usually fine for most woods, with acrylics you can get little chip knockouts from the flashback which masking does not prevent.
Very interesting. Wonder what they use to make it non-combustible?
pretty good chance your power is too high if that’s happening. speed up or lower power and that should go away.
Thank you! A great use for scraps.
Industrial non combustible paper (think hollow core doors, non-solid wood IKEA furniture, wallpaper lining etc) typically uses aluminum hydroxide. Fire retardants for fabrics are usually some kind of salt solution.
Very interesting. Thank you for the info!
These look great. I haven’t worked much with acrylic. What are the benefits for having acrylic raised off the crumb tray?
You can also mask, but this is definitely quicker and less wasteful!
I mask it and raise it. It keeps the flashback from the tray marring the under side of the acrylic.
I had this problem a lot when working with green-glass acrylic for my clock. The edges would look notched if the laser-power was slightly to high. Even through the masking it would remove some the edge and it wouldn’t look perfect.
Neat idea, thanks for sharing.
