What is Laser Engraving?

​

It’s exactly what you think it is! Laser engraving is the use of a laser capable of being powered at multiple heat levels for various materials and purposes. Light from the laser removes layers of the original material, leaving behind an indention with higher contrast and a different surface texture.

Etching

​

During the process of laser etching, materials absorb heat from the laser causing an expansion to the desired area. Color change occurs and the surface cools down leaving a permanent marking. 

Engraving

​
​
Engraving is a more drastic approach to laser usage. This process uses more power to get a deeper carving into the material.

Ablation

​

Very similar to etching and engraving, laser ablation removes surface coatings, with micrometer precision, leaving behind micropatterns. Patterns such as grooves, dimples, and other free forms can be ablated into various materials to achieve desired textures.

Laser Engraving Advantages

  • Precision & Accuracy – Through the use of a laser beam, detailed engravings, and those with intricate designs, are easily attainable.
  • Versatility – The wide array of compatible materials makes it a great tool for many jobs. Different thicknesses of metal, plastic, wood, glass, and other materials can be engraved given the right laser and settings.
  • Efficiency – The rate at which items can be completed relies directly on material, design, laser power and overall size. Nevertheless, many designs can be completed in just a few minutes.
  • Personalization – With the ability to etch and engrave nearly any design onto a targeted material, one-of-a-kind products are made every day using these technologies.
