The Laser Thread

Well, I got some laser time in! 700mm/min, 100% power on these.

Wow! Those look incredible. I assume you're using a MOPA fiber, correct?

Thank you. A lot of time went into the design coins and figuring out brass colors. Then there is the time engraving them and using the fiber laser to color them.

Yes 100W JPT MOPA fiber is what I used. Though you should be able to get some of the colors with a non-mopa.

I wanna figure out how to do curved jimping using 3d engraving, could be super helpful

I would create an stl with the pattern your looking for and convert that to grayscale. Then engrave it on a few test pieces to get the depth your looking for.

Engraved on the back of a custom 3d printed lightbox I designed and made today. The 2W IR laser does a really good job marking black PLA

Those look great - did the colors come out that good with just the laser? Fiber laser?
