Overview
An 8.5 oz spray that adds a black, high-contrast marking layer to metal, ceramic and glass before engraving, made for use with CO2, fiber and diode laser engravers.
This is a consumable applied before engraving, not a laser itself, and its compatibility is stated by minimum power per laser type rather than by brand alone. Shaking technique matters too, xTool specifically warns against shaking it vertically.
- 8.5 oz can, clog-proof nozzle
- Rated for CO2 (25W+), fiber (10W+) and diode (10W+) lasers
- Non-corrosive, fade-resistant black finish
- Works on metal, ceramic and glass
Who it's for
Fits owners of a CO2 laser at 25W or more, a fiber laser at 10W or more, or a diode laser at 10W or more who engrave metal, ceramic or glass and want a darker, more consistent mark than the bare material gives. Not useful without a laser meeting those minimums.
Strengths and trade-offs
Drawn from this product's published specifications.
- Works across CO2, fiber and diode lasers
- Non-corrosive, fade-resistant formula
- Clog-proof nozzle for an even coat
- Needs a laser above the listed minimum wattage
- Must be shaken a specific way, not vertically
- Should be kept out of direct sunlight
Performance notes
The spray leaves a powder-based coating that the laser marks instead of the bare surface, producing a darker and more even result on metals, ceramics and glass than engraving without it. xTool specifies shaking side to side rather than vertically, since vertical shaking can create a bulge at the bottom of the can, and the can should be kept out of direct sun.
