Verdict

The source decides what a machine can make. Fiber marks bare metal and will not cut wood; CO2 cuts everything organic and passes through clear acrylic; diode is the cheap way into wood and leather; UV marks glass and clear plastic that the other three cannot touch.

Why this is the verdict, with sources

The comparison nobody in this category publishes is the one across technologies, because every manufacturer sells one of them. A buyer arrives asking “fiber or CO2” and finds four separate marketing sites, each answering “ours”. The answer is set by material rather than budget: a fiber laser will not cut plywood at any wattage, and a CO2 machine will not mark bare stainless without a coating. Wattage decides how fast the job runs; the source decides whether the job is possible. Every figure below carries the manufacturer page it was read from and the date it was read.

Not yet populated

No machine carries a full sourced review yet. A machine appears in this table once somebody has read its manufacturer’s own documentation and entered the figures with the date they were read — never because a listing mentioned a number. Until then this page states what the table will hold rather than filling it with values nobody checked.

The live Amazon catalogue underneath it is a different tier and fills on its own: see the category pages for fiber, CO2 and diode machines.
