OMTech Laser Marking Spray, Metal Laser Marking Fluid for CO2 Laser Engravers, 4Pcs 13oz Aerosol Spray for Black Laser Engraving Metal, Laser Ink for Aluminum Stainless Steel Brass(4 Pack)

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.

Works perfect

I have used this marking spray a few times and each time it has worked perfectly. This spray is advertised for use with 25w and above CO2 lasers. The laser I have is an xTool D1 Pro, 10w diode and it works perfectly fine. Just follow the instructions on the can and don't cut corners. The spray that is left after the laser process cleans off easily under water at the sink.

Laser marking on metal for hobby lasers that are not powerful enough to cut into the metal is a great workaround. You should test before setting the speed/intensity to avoid ruining your project. Ask me how I know. Works well once you have done your research. Durable finish

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

I tried this with a diode laser engraver (XTool M1 10W) and brushed stainless steel. Very satisfied with the results - the coating left on the stainless is hard and dark. It appears to be durable to normal handling. I've tried limited tests to see if it would scrape off or flake off, and it appears to be firmly adhered. I had to be careful handling the pieces before laser engraving. This spray doesn't adhere like paint, but more like a powder. It doesn't take much of a touch to disturb it. But it washes off with water, so all I did was clean up the disturbed pieces, recoat them, and handle more carefully. I had much better results with this OMTech product than with a CerMark spray, and the OMTech is certainly more affordable by volume. My next test will be trying to mark brass with OMTech and a CO2 laser. Neither spray works with the diode laser on brass.

Bold Black Engraving with my 10W Laser, Perfect printing on stainless steel. Easy to clean after marking. AAA+++

Works very well. Easy to use

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

Better than Brilliance brand.

3 stars because the product itself worked pretty well. I wish I’d taken some pictures, but it was a rush order (with how late the spray arrived) and I just had to get the product out the door. Prior to spraying, I cleaned all of the materials, 25 steel dog bowls, same design, same set up etc. I sprayed each bowl the day before I used the laser, approx 28 hrs before I used the laser on them. That said, they looked dry only minutes after I sprayed them, ensuring an even application. **PLEASE NOTE!! The nozzle somehow got stuck “on” and continued to spray despite the fact my finger was not even on the nozzle any longer. It would continue to spray for a good 2-10 seconds before stopping. This resulted in a fair amount of the product being wasted. After the first few times of it happening (cause it was not doing this consistently, making it harder to predict), I took the cap off to see if there was anything I could do to clear it out or stop that from occurring again. There was nothing that I could see that was obviously causing that issue. To be honest I didn’t have too much time to sit an inspect/troubleshoot, so I ended up just trying to have additional bowls ‘ready’ on a jig so if it was continuously spraying and not able to stop it then it I could at least get some of the product on the outside of the bowls. That was kind of irritating, given how pricey this stuff is, and how long I had to wait- with rush projects to get done. I also noticed that there was some areas that were lasered (again, same settings design and material, even coats of product) that appeared ‘pitted’ or bubbled somehow. Whether this is an issue with the product or the material is an unknown to me at this point, as I don’t have enough experience to say. As I said, it took a long time to get here (YYC, AB) and it’s painfully expensive, especially when considering how much was wasted to a faulty spray mechanism at the top. If I could do half stars I’d maybe do 3.5 ⭐️ . If there was no faulty spray mechanism costing me wasted product I’d give a 4 ⭐️ if there was better shipping time, price and no inconsistency in the laser result I’d give a 5⭐️ If anyone is wondering, as I was - I was using the Xtool F1, with the 10w (Blue) giving the best result, I used 75% power due to the material being sort of tricky, and 230 for speed and it seemed to do the trick on a stainless steel dog bowl from Princess Auto. I highly, HIGHLY recommend ordering extra if you have a project that you are unsure of how the material will do, settings, all of that, and that you make time and allowance to play with the best settings for your project. I used another product recently (shipped in powder form) that was NOT GOOD, and it stated no where on the page or pictures that it was meant for co2 lasers only. I found out only after I opened it up and read the instructions for mixing. So, my advice is make sure that the product works for the type of laser you are working with because YES, it does matter!
