Laser engraving crayola is something you don’t see too often but the results come out pretty good. Wax is a tough material to laser engrave because it tends to melt when heated up, so I grabbed some Crayola crayons that I got at a manufacturing trade show (yes, some companies are getting creative with their swag), and gave it a try!
Got a bunch of metal stuff engraved and I wanted to do a slight change of pace… keep the mind sharp!
I could have spent a bit of time making a custom jig for my soon-to-be engraved Crayola but I decided to just grab some Lego to build a quick and dirty holding jig to prevent them from rolling off the bed. I also have larger production runs that I don’t use jigs, it depends on the material and application of our work.
My guess is that the darker the color, the more apparent the engraving will go. My goal here was to vaporize the paper holding it in place and only very slightly engrave into the wax as it would just pool around in the bottom of the engraving, removing some of the sharpness I was trying to achieve.
The blue came out pretty good as with the orange.
From the picture above and below, the Crayola came-out pretty good, if I had to redo these, I’d use slightly more power or a slower speed (both do the same thing) in order to burn off a bit more depth. It’s a fine line between producing a soggy mess and a sharp engraving.
You can watch the video below of the entire process, filmed here at CNCROi.com HQ. Now you know the secret behind crazy fast and easy to use jigs, Lego! This must be the first time these two worldwide-known brand names have come together with a third, Trotec!
