A CO2 laser has an output of 10,600 nm. These lasers operate by continuously broadcasting the light onto the part.
There are two main types of CO2 lasers. One has a gantry system that moves the laser over the part. These typically use glass tubes that frequently need replaced, as well as having moving parts that fail over time. In general, these CO2 lasers start at a low cost but have higher maintenance cost over the lifetime of the laser, along with shorter service life.
The other type of CO2 laser is one that uses a series of mirrors, called a galvanometer, to move the beam of light onto the part below it without moving the laser head. Automark offers these CO2 variants, as they operate continuously for years without costly maintenance.
Substrates usually include organic materials, like leather, paper, cotton, cardboard, wood, rubber, and some acrylics. To see if we can mark your part, feel free to reach out to us as we offer free part marking.
Lasers are regulated by the FDA due to the radiation they emit and they are classified based on the damage they can do to skin and eyes. A class I laser is a laser that is totally enclosed with no way for the beam to escape. This is similar to a laser printer and cannot cause eye or skin damage with normal use.
A class IV laser is the highest classification of laser meaning they can cause skin and eye damage, and class IV specifically can cause damage if viewed indirectly. A laser, when properly used is extremely safe.
Operator safety is paramount, so we offer an entire line of lasers that take a Class IV laser, and turn it into a class I laser by enclosing it in a sealed box. This is the E line of fiber lasers. The CO2 line is only offered in open laser configurations.

A standard laser has a focal point with a tolerance based on the distance from the lens. This varies and depends on the lens size selected. This focal height is only a few millimeters. A round part is challenging for two reasons. The first reason is the distance is changing as the slope of the Z-axis declines around the part. The second reason is because the certerpoint of the galvanometer is creating a “longer” traverse to create the same image. This means that if a person was to use a standard, 2D, laser to mark a round part, they may get elongated markings as the beam trails off over the edges.
We can use a rotary to hook the part onto and spin the part. The rotary feeds information into the laser, so the laser knows where it needs to mark. This is done if greater than 120 degree printing is required. Smaller rotaries, like 50mm are perfect for rings and small items, whereas, the larger 100mm rotaries are perfect for mugs and firearms. 3D Laser System
We offer laser solutions for moving parts like bottling operations, assembly lines, and conveyor belt part marking. Special photography can be implemented to identify part orientation so fixtureless printing is capable. For details on this and other more customized solutions, contact your Automark representative to discuss your program in detail.
