For a while I've been wondering if you could flood the chamber of a laser cutter with CO_2 routinely, not just to prevent fires but to prevent the scorching that laser cutting leaves on wood. If that would consume too much CO_2, would it be workable to instead spray it topically onto the point of the cut, a bit like the inert shielding gases that some forms of arc welding use?
- markvdb 11y agoAir assist is a classic thing on many decent laser cutters, especially for the reasons mentioned. On our lasersaur for example, a builtin air nozzle blow compressed air at the place where the laser beam hits the material being cut...
- danshapiro 11y agoGlowforge does have both air assist and purge air FYI.
- leoc 11y agoOn reflection this probably can't work, as apparently wood melts only at stupidly high temperatures. Though maybe a lower temperature to embrittle the carbon would be enough?
