Brilliance Laser Inks 12 Oz Laser Marking Spray - Black, Permanent High Contrast Metal Marker Aerosol for Fiber, YAG, Diode, and CO2 Laser Engraver Machine, BLI101

Worked great for metal on my diode laser.

A bit $$$ but it works great ( diode laser engraver)

Good laser marking spray and cheaper than alternatives. We use it for our glowforge. Metal pieces come out nice and dark.

I had mixed results using this product. My application required text and photo on a memorial plaque. I started with anodized aluminum sheet with a satin finish. (AKA Brush finish) The text transferred well, it was black and well defined. The image (B&W bit map) printed well, but due to the satin finish, directional lighting was critical to viewing the image. Depending on the viewing angle, the lenticular scratches reflected the light in such a way that the image appeared as a negative. Viewed from another angle, the image appeared as a positive.Realizing that the lenticular scratches were the problem, I sanded through the anodized finish with a random orbital sander. I sanded the aluminum down to a matt finish starting with 80 grit and ending with 1000 grit paper. After degreasing with rubbing alcohol, I ran several trials at different speed and power settings on my 30W Epilog laser. The matt finish did not produce the positive / negative issue of the satin finish. However, I had trouble with the fine matt finish not being able to reproduce the B&W tonal range of my image. In general, the image contrast was low. Overall it was either too light or too dark depending on my settings. I scrubbed the plates with the orbital sander to remove the image and text. After several trials, I discovered that the 1000 grit matt finish was too smooth. My best results were achieved with an 80-grit matt finish. The text always printed well regardless of finish, and I had reasonably good tonal range on the B&W image using 600 DPI, 75% Speed, 90% Power. (1200 DPI always printed dark and 400 DPI did not retain image details.)In conclusion, my best results were achieved when the aluminum had an 80-grit matt finish. Fingerprints are a problem. Degreasing is essential and avoid touching the engraving surface. The engraving was not as durable as I expected. It was very easy to scrub through and sand the image off for successive trials. I applied a clear lacquer finish to keep the aluminum from oxidizing. The finished product will be framed under glass.

Very economical way to purchase this much needed spray. We use it constantly on jewelry and metal tags. One of the best prices we have found and shipping was quick. Would buy again.

With this ink I can quickly place high quality detailed permanent images on metal with my Fiber Laser! I could not accomplish my projects without it

I have only used less than half of this marking spray and it started spitting instead of spraying. I took the top off to clean it really good and make sure I shake it really good in between each use. Nothing has helped. It's now garbage. As much as this product is, it should last to the very last drop. Don't waste your money.

It is easily applied, evenly dries, and washes off with little effort. Yes, it’s costlier than many alternatives but is just plain perfect for my purposes with the XTool 20w D1 machine. That said, I have since learned how to get a circular design engraved on a curved surface with the rotating Xtool accessory and not get an oval.
