Hi everyone!
I've been laser-cutting acrylic parts for a year now, mostly for sign letters. Up to now, I used double-sided tape for putting together my work.
Recently, I was asked to make acrylic displays to protect some collector items, basically boxes with an open bottom. I laser-cut the parts in 1/8'' acrylic and used methylene chloride (a solvent) to glue them. To my surprise, all the smooth, laser-cut edges would immediately crack in contact with the solvent.
After research, I learned that laser-cut acrylic edges are brittle and under a big mechanical stress, and will crack with solvents or alcohol... unlike routed or sawed edges. Wow, this is a big drawback no one told me about!
So now, I am looking for a bubble-free, clear glue that will do a nice job without cracking the laser-cutparts... I was thinking about trying Weld-On #16 glue. Anyone as any advice?
Thanks!
Fred
