OMTech Laser Marking Spray, Metal Laser Marking Fluid for CO2 Laser Engravers, 13oz Aerosol High Contrast Black Spray for Laser Engraving Metal, Laser Ink Agent for Aluminum Stainless Steel Brass More

Este spray es una herramienta altamente recomendable para cualquiera que tenga una láser CO2, he podido grabar varios elementos de metal y quedan hermosos. El valor recibido por lo que pagué es justo. Es fácil de limpiar con agua después de grabar y ya ví que hay otro spray en color rojo que voy a probar. Recomiendo al aplicar hacerlo en un lugar aireado y usar mascarilla porque el spray parece una espuma pero se seca y se vuelve polvo al contacto con el aire. Se debe dejar secar bien antes de grabar. This spray is highly recommended for anyone who owns a CO2 laser; I've been able to engrave several metal items, and they turned out beautifully. I feel I got good value for my money. It’s easy to clean off with water after engraving, and I’ve seen that there’s another spray in red that I’m going to try. I recommend applying it in a well-ventilated area and wearing a mask, because the spray looks like foam but dries and turns into dust when it comes into contact with the air. You should let it dry thoroughly before engraving.

Better than Brilliance brand.

I didn’t expect a spray can to change what my laser could do—but this one kind of did. I’ve always known my CO₂ laser isn’t meant for bare metal. Stainless, aluminum, brass—normally it just reflects or lightly etches at best. After trying the OMTech Laser Marking Spray, I went from “not possible” to clean, dark engravings that actually look intentional. The Moment It Clicked The first time I wiped off the excess coating and saw a deep black mark left behind, it honestly felt like cheating. It bonds during the engraving process, so you’re not just discoloring the surface—you’re leaving a durable mark. It’s More About Technique Than the Product This isn’t a “spray and magic happens” situation. What made the biggest difference for me: Light, even coats (too thick = muddy results) Letting it fully dry before engraving Dialing in power/speed settings per material Once I figured that out, results became repeatable. Where It Shines (Literally My Use Cases) I’ve gotten the best results using it for: Tool labeling (no more stickers peeling off) Small metal tags and plates Custom branding on parts It’s especially satisfying on stainless—super crisp contrast. Not Perfect—But Close Enough It can get messy if you overspray, and cleanup is part of the process. But compared to buying a fiber laser? This is a no-brainer workaround

Ce produit est idéal pour la gravure sur aluminium anodisé. Je le rachèterai sans hésiter pour mes prochains travaux de gravure.

We used this to aid in laser etching glass with a bambu 40w laser. It worked very well. It is super easy to apply, super easy to remove and left a nice frosted white finish on glass. We haven't tried it on metal yet, but will soon. The only complaint I have is that it is 40 bucks a can, but other than that it is awesome. Goes on nice and smooth, dries quickly, works well and rinses right off. Great product.
