For those not familiar with the different laser engravers out there, there are two common types. CO2 or Fiber laser. CO2 lasers are the more affordable option. They can cut and engrave soft materials like wood, paper, and plastic. Here are some examples I did back in Pittsburgh.
With regards to firearms a CO2 laser can engrave and remove anodizing but it is not powerful enough to etch into metal.
Fiber Laser For Real Firearm Engraving
I came across LIT Laser from a local guy, Steve Mitts, offering up laser engraving. Having dabbled a little in laser firearm marking I inquired about his services. I was pleased to learn Steve has a fiber laser. He has since helped me customize some guns and accessories.
What sets Fiber lasers apart from CO2 lasers is partially the power but also the wavelength and pulse of the lasers. Fiber can etch metal and bleach pigment out of polymer like PMAGs. Here are some projects I did with Steve’s help.
While fiber lasers are not really new, what LIT Laser showed is something new at TriggrCon 2019. Just like a CO2 laser, fiber lasers are relatively two dimensional. You can only engrave flat surfaces. You can get fancy with a rotary tool to engrave a cylindrical object. But you typically cannot engrave complex shapes. Well, that has changed at LIT Laser with their 3D fiber laser.
With LIT Laser’s new 3D laser system. It is a combination of proprietary software and hardware but the results are amazing.
The largest object that can fit in their 3D fiber laser is 13.5″W x 9.5″L x 4.625″H (mm)
Another benefit with their 3D laser system is that you can mark on complex surfaces without the need for a rotary tool.
For more information go to LIT Laser’s website. Although their new 3D fiber laser system is not up on their website just yet so you should call them for more info.
