@Jasper_Janssen apparently what @Jacob_Merrill said is over your head. If you use a laser to cut a flammable material like paper, you risk it being singed or even catching fire. That’s why you use an inert shield gas around the laser head to prevent it.
@Christopher_Gaul oh, is that what he meant. It wasn’t so much over my head as underneath my intelligibility threshold. It sounded as if he meant a gas laser, as opposed to a solid state one.
Inert gas shielded laser cutting still isn’t magic — the cuts won’t be any thinner than with the exacto knife, although they’ll probably be able to change direction more easily. The added expense however would be enormous, not least in the supply of inert gas.
A vacuumis cheap enough…
Percision is good for some things,
Gold leaf is really really thin,
Paper is really cheap, and re-usable
and gasifiyable.
printing a phone may be cool some day
Graphene is printable
I have ideas, and I try to help,
sometimes they may even be wrong…
I don’t think this is the case here, as light can be pretty good with tolerances,
visable - 390 to 700 nm
and you don’t have to see to cut,
