BRILLIANCE LASER INKS12 Oz Laser Marking Spray - Black, Permanent High Contrast Metal Marker Aerosol for Fiber, YAG, Diode, and CO2 Laser Engraver Machine, BLI101

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

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

If anyone is hesitant about ordering this based on price, don’t delay and order it! This product works better than I expected. I was nervous about spending the money because I’m new at layering, but I’m glad I did. Dry moly does the job, but based on everything I read, it can cause damage to your machine from the fumes. Also with dry moly, to mark stainless you have to go 5-10 passes to get image to show up and even that is inconsistent which takes up valuable time. With this spray I did two passes and images are super crisp and no dead spots(I did a test run and one pass works, image gets crisper with a second pass). The axe was done with dry moly for the image and Brilliant marking spray for the words. As you can see, the image done with dry moly looks a touch faded. That was after 5 passes, whereas 2nd Place was two passes with the Brilliant marking spray. I’m still getting the hang of doing even coats with the spray as going heavy causes it to have running with the spray, though it doesn’t affect the lasering process, it does waste product.This product is definitely worth the money. Hope this review helps other small business owners and/or people with their decision to buy.

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.

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

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.

whats strange about this stuff is that once it is sprayed out, the power and speed settings don't seem to matter! Did a few material test arrays - and with this stuff properly applied the lightest setting is as dark as the heaviest setting - and its black; dark black.I was having mild success with a 20w diode and stainless, but was not getting the inky black I wanted. This spray is what it took - I am having success at 100% power and 100 to 200 ms speed .

It went on and off easy and dries fast. It's really like a powder when it dries so don't touch you work area. The etching came out very clear and detailed. I ran this on an xtool S1 40 watt diode laser. Very pleased and will buy again. The only thing I'd complain about is the price. But you get what you pay for.
