Laser etching metal with a CO2 laser cutter requires an etching compound in order to leave a mark. The most popular laser etching compound is a great product called Cermark, but it’s a little pricy. In this video I’ll show you how you can use a can of Industrial Dry Molybdenum (Moly) Lube to achieve similar / adequate results.

One thing I love about woodworkers and metalworkers and all the other similar and allied trades is how there's often a different, creative and perhaps a less expensive way of doing things. And there's always something new to learn. I'm a boatbuilder but today I was learning how to split hazel withies to make woven wooden hurdles. Also got to use one of my favourite tools, the drawknife! I look forward to more of your videos. Keep up the good work!
Haha, exactly, Brian! Always multiple ways to do things - some expensive, some cheap, and usually they result in roughly the same outcome so unless you need to do the same "cut" or action or what have you hundreds of times a day and the expensive option makes it easier, let's all remember the "cheap" way. Cheers! 😊
Thank you. The idea with the weight is great 👍🏻
You’re welcome Susanna!! 😊
Great tip. It's a money saver on my projects
Glad you liked the video! Cheers!
Looking forward to the comparison!
Awesome, thanks for following along! 😊
Some motor oils even have molybdenum disulfide in them. It is a friction reducer and is similar to graphite in appearance when in dry form. One brand of oil known for having it is Liqui Moly which is made in Germany
this marking compound does not peel off in time?
Can you use black spray paint for reflective surfaces?
A Sharpie marker works just fine to etch dark on metal and stainless steel. I do it all the time.
Interesting! I've never tried that, I'll have to give that a try!
What about flat black spray paint?
I'd love to see the comparison to CerMark!
You got it Eric! Stay tuned for that!
"molly denum" haha :p
I’d love to see a comparison with Brilliance Metal Laser Spray. It’s cheaper than CerMark by about half.
Good call! I’ll add that to my notes! ❤️
Thanks for the video. i had to look up one of your other videos to find that the co2 laser you're using is 80w. Might be a good idea to include the power in the video for others. Also knowing how long the engraving took would also be help.
Hey Andrew, good call! I'll try to be better about having an on-screen info panel that says my tube wattage in addition to the power and speed in future videos. Thanks for the tip! Cheers!
Have you tried using Molybdenum Disulfide Powder mixing with Acetone and paint it on stainless steel , Im chemical engineer . it save ur money.
Nice! I'll have to look into that! I'm sure that's what's in the can!
How much should we use each? Please sir ! I really need this

Would Black spray paint work?
I haven't tried on metal, but I'm pretty sure the paint would just get "burnt" off in the area of etching. That said, if you wanted to entirely coat a piece of metal in spray paint and "etch away" the paint to reveal metal, that would work! But not for etching a "positive." Hope that helps!
@@FarbulousCreations I might try this tomorrow. I only just discovered the concept of laser etching with low power lasers, but if it's a case of allowing the heat from the laser to be absorbed more effectively and vaporise the base metal rather than the heat fusing the compounds in the etching spray with the metal I'd imagine anything opaque would work
I may be completely wrong about how the process works, I'll update if it's successful!
It's pronounced muh-lib-duh-nuhm.
Tomato, tomahto 😉
Rubbish
Do you have any other way !!!
