Can a CO2 laser melt and fuse glass powder frit?

I was wondering if anyone has tried to use glass powder frit on a project.

Well you did post this a few years ago :slight_smile:

Nice still having all the old posts to search through.

Sand and glass frit are a bit different! :grinning:

I was just curious if anyone has experimented with it yet or will I be the first.

I’ve molten basalt powder and ceramics in my Fabcreator. Glass has a lower melting point so should be no issue temperature wise. How to prevent it from beading up etc is something else. My guess is we reached around 1500 degrees C

If beading up is a problem you could probably add a flux like calcium oxide or lithium oxide. I guess it depends on the type of glass the frit is make of.

Hi Ned, I’ve not yet tried adding any flux but that would be the goal to figure out next time I try. Has anyone seen some 3d sintering addons for laser cutters?

My friend at work does a lot of ceramics. She’s going to be with a lot of other ceramic people this weekend so she is going to see if she can get me some samples of different combinations of glass and flux.
