Laser Engraving has evolved dramatically over the previous decade or so. When I started working in this business, if you needed to have a laser at your manufacturing facility or shop it’s important to have THREE THINGS: Highly Trained Personnel, Patience and very DEEP pockets.
In the previous 10-years or so, computing power, solid-state lasers and deployment of advanced software has helped to drop the prices considerably, the required skillset to own and operate a system is also quite low and improved reliability means that system maintenance has become significantly simplified.
So, let’s get to the meat of this Article.
Laser MARKING: TIPS and TRICKS
1. First and Foremost, ensure you have the correct Wavelength!
The Wavelength of the laser is critical to laser etching.
For example, Let’s say your major business is custom firearms. Most people begin with a simple CO2 laser having a Wavelength of 10,600nM. These are low-value, low-barrier techniques meant for engraving and marking organic materials. Wood, Paper, Glass and Stone to name a few. A CO2 laser is a GREAT selection for engraving and marking the Wood Butt Stocks and Polymer Grips of guns, but isn’t going to do a lot in the way in which of engraving the steel parts of the firearm.
In order to successfully mark and engrave with any depth in metals, we need to change the wavelength. Here, the appropriate wavelength for MOST common metals is about 1uM. Why do I say about? Simply put, there’s a number of variations for the 1uM laser, …
