> all sheet metal that's cut for home appliances and so forth, was starting to be cut by high-power fiber-lasers of the kilowatt-type power levels.

Shame this tech has yet to trickle down to the home-hobbyist level.

Having my 3D printer direct the end of a decently powered fiber laser cutting head would be a nice feature!

It absolutely is available. It's just powerful lasers are very dangerous to your eyes, and you better really know what you're doing.

You can buy a 1.5kw laser cutter for $35K on Aliexpress.

Available yes but it's still the realm of people with a good amount of disposable income such that they can drop 1-2k+ on a hobby.

I bought CO2 laser for like $60 off eBay and it works fine with my 3d printer tho it will never be able to cut metal.
