Frequently Asked Questions About the 40W CO2 Laser Engraver

Laser engraving is a good way to make memorable gifts for friends and family. You can etch a variety of materials with your own design. If you are looking for a new project, consider buying a laser engraving machine for your home.

How deep can a laser engraver cut into materials?

This will all depend on the type of material you want to cut. Most laser engraving machines do not fully cut the material. There are some models that are made for completely cutting through materials. Most engravers make a surface impression on the material. For a 3mm acrylic piece, you can expect the engraving to be 0.25mm deep. Wood can be cut up to 0.5mm deep. If you try to engrave any deeper, you may run into problems. For all types of laser engravers, eBay offers a wide variety of selections.

What type of material can be engraved?

An engraving machine can etch and engrave a variety of materials. You can consult your owner's manual that generally comes with engravers available through eBay to see if the material can be used with that particular engraver. These materials can be engraved:

  • Thin metals: Stainless steel and spring steel
  • Plastics: Acrylic and ABS (acrylonitrile butadiene styrene)
  • Cloth: Suede, felt, hemp, cotton, and leather
  • Foam: EPM and Depron
What is the difference between an engraving and an etching?

Laser etching and engraving are used interchangeably, but there are a few differences between the two art forms. Laser engraving cuts a design into the material. The cut is deep enough that you can feel it on the surface. This is cut with a high heat laser that causes the material to vaporize. Most materials can be engraved. Laser etching is almost the same process as engraving. The difference here is the depth of the cut. There is usually no more than a 0.001-inch cut to the surface. This is typically used for jewelry and thinner materials.

What types of graphics are ideal for cutting into materials?

You can engrave a wide selection of bitmaps, logos, photos, and AutoCAD files into the material. If the graphic can be printed, it can be engraved into your project. In order to access the graphic, you will need an Illustrator or .eps file. eBay offers many options for use with laser engraving.
