You can't cut tempered glass or across glass with fracture lines.

So, a waterjet cannot cut tempered glass. What about lasers and plasmas; what materials are they unable to cut that waterjet can? I know they can't cut food, but a waterjet can. I'm wondering what metals, glass, or composites lasers and plasma can't cut.

Laser can only cut metal up to 15mm (Newer high end machines upto 25mm) water jet can go up to above 150mm.

Laser & plasma usually make a mess of Aluminium, water jet cuts aluminium perfectly.

Laser can struggle on reflective materials such as brass, water jet has no such probles.

Plasma can only cut conductive materials... Abrasive Water jet cutting can cut anything.

List is endless.

I would like to point out that waterjet will NOT anneal the edges of your metal parts either. Try pulling a freshly cut part off the work platform of a laser or plasma cutter with your bare hands... and 20 second after the cut.

PLASMA: conductive materials, best suited to material 2" and under
LASER: almost any material, best suited to .5" and under

downside of both, heat affected zone

WATERJET: everything but tempered glass, no HAZ for most materials ( max 100Deg C temp change), up to 12" in some cases 15"

Ps waterjets were originally pioneered to cut lumber in the 50's, laser probably could, but it's not economical compared to saw or water jet.
Plasma can't cut wood, unless it was maybe soaked with a highly conductive liquid, even then you'd do more burning than cutting, same way oxy-fuel torch would do to wood or copper.

cutting lexan on a laser works but it produces terrible fumes
