UV lasers use a highly absorptive wavelength (355 nm) to mark parts. This high absorption rate allows UV lasers to perform "cold marking," ensuring that no extra heat stress is applied to materials, including those with high reflectance such as gold, silver, and copper.
What is the difference between laser marking and laser engraving?
Laser marking discolors the surface of the material, while laser etching and engraving actually removes a portion of the surface area as it marks. The major difference between laser etching and engraving is the depth to which the laser penetrates the surface.
How do laser engraving machines work?
Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.
How thick can a 30w laser cut?
30W/40W/60W CO2 Laser Tube Design for hobbyists, crafters to cut thin materials (<3mm) and engrave fine quality pictures on smooth surface.24 Aug 2013
How deep can a fiber laser cut?
Fiber laser cutting systems can certainly cut more than one inch thick with higher Fiber laser powers and even cut faster when utilizing nitrogen as the assist gas, but the “sweet spot” where the most significant benefits are realized is in the 1/2 inch and under range for steel when making comparisons with CO2 systems
How thick of metal can a 50w fiber laser cut?
0.1mm to 1mm
Will a 30w laser engrave metal?
30w is used for marking and engraving on metal material surface and some nonmetal materials.7 Dec 2017
How deep can laser engraving go in metal?
How Deep Can You Laser Engrave? When it comes to deep engraving, the depth can easily reach a few millimeters into metals. This is in stark contrast with regular laser engraving, which is typically only a few microns deep. But regular laser engraving can also be deep—up to 500 microns.27 Jan 2021
How deep is laser engraving on wood?
In 3mm acrylic you can expect around 0.25mm (0.01″) deep, and in some of the woods the laser will cut up to 0.5mm (0.02″) deep. To go further into the material than this will increase the risk of undesirable damage such as warping (in acrylic) and excessive burning (in timber).22 Apr 2015
How deep should an engraving be?
A good rule of thumb is that the line width of the engraving should be equal to or greater than the depth of the engraving. You cannot engrave a 0.003-inch-wide character 0.010 inch deep and maintain a flat floor finish, but you can engrave a 0.003-inch-wide character 0.003 inch deep.1 Mar 2017

What can I do with a fiber laser?
Fiber lasers are everywhere in the modern world. Due to the different wavelengths they can generate, they are widely used in industrial environments to perform cutting, marking, welding, cleaning, texturing, drilling and a lot more. They are also used in other fields such as telecommunication and medicine.26 Nov 2020
Can a fiber laser engrave metal?
For bare metals, fiber lasers represent the engraving method of choice. Fiber lasers are ideal for marking many types of aluminum, brass, copper, nickel-plated metals, stainless steel and more - as well as engineered plastics such as ABS, PEEK and polycarbonates.27 Sept 2017
