the claim

A CO2 laser can engrave bare uncoated metal such as stainless steel.

the verdict
CONTESTED PARTIAL
Recorded sources
1 source for · 3 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that a CO2 laser can engrave bare uncoated metal such as stainless steel?

Partly. One peer-reviewed study shows a CO2 laser cutting 316L stainless steel, which partially supports the claim but addresses cutting rather than engraving and does not state whether the steel was bare or coated. Other CO2 laser engraving studies demonstrate the process only on plastics such as PMMA and epoxy resin, not on bare metal.
