Fabric Engraving – Leather
Essentially, the depth of material removal differentiates these three laser processes.
Fabric Engraving
Laser engraving is a non-contact process where a focused laser beam removes material from a surface, creating a permanent mark. This is achieved by converting light energy into heat, vaporizing the material at the focal point. Engraving depth is adjustable by controlling laser power and speed.
While often used interchangeably, engraving and etching are distinct processes. Both permanently alter a material’s surface by removing material, but there are key differences between the two.
Engraving, Etching, & Marking by Laser
The primary distinction between laser engraving, etching, and marking lies in the depth of the material removed by the laser beam.
- Laser Engraving: Involves removing more than .001 inches of material, creating a noticeable depth. Common examples include checkering gunstocks and deep engravings on wooden signs.
- Laser Etching: Removes .001 inches or less of material, often used on coated metals to create a contrasting effect. This technique is popular for personalized drinkware.
- Laser Marking: Does not remove material but instead creates a darkened or contrasting mark by oxidation or a heat-affected zone. Primarily used for serial numbers, barcodes, and logos. Marking sprays can enhance this process on certain materials.

Fabric Laser Cutting
Often when we talk about manufacturing with lasers, we focus on cutting or engraving rigid industrial materials like sheet metal, plastics, or wood using powerful CO2 or fiber lasers. But CO2 laser cutters can also be revolutionary for cutting fabric and textiles. Let’s take a look at the benefits of cutting fabric with a laser, as well as considerations for optimum fabric-cutting results.
Benefits of Laser-Cutting Fabric
Laser cutting saves a tremendous amount of time compared to traditional techniques for cutting fabric. It offers more repeatability than traditional cutting methods, making for a more consistent product during large-scale production.
Laser cutting is a no-contact manufacturing method: No cutting tool touches the fabric, and the fabric does not need to be clamped or secured to the cutting table. Few moving parts mean less maintenance for the machine and reduced wear and tear on the tools involved. Workers don’t need to be in direct contact with the product during processing; they may even be able to perform other tasks while the laser operates.
The reduced labor and increased consistency and efficiency of laser cutting mean, in the long run, that these machines often substantially reduce users’ production costs, despite the high initial investment involved in acquiring a laser cutting machine.
The laser also melts and seals the edge of the fabric during cutting, which prevents fraying and eliminates post-processing steps.
