Are you new to laser technology?
If you plan to start a project involving lasers, you should first understand the differences between the two primary methods: laser etching aluminium and engraving steel. For a beginner, these processes sound alike, but their nature and output make them glaringly unique.
In this article, we’ll tackle the difference between stainless steel engraving and etching to help you determine the better process for your application.
Laser Etching
Laser etching is the technique of melting and altering the micro surface of a material using intense heat. Laser etching employs a large quantity of energy provided at regular intervals via a laser beam.
The melted material expands and leaves a texture or raised mark with a depth of approximately 0.0254 mm (0.001″).
Pros and Cons of Laser Etching
Pros
- High precision
- Speedy process
- Versatility
- Cost-effective
- Ideal for mass production
Cons
- Decreased durability
- Achievable only by fibre laser
Using Laser Etching
Laser etching is best utilized for common materials like stainless steel, different grades of aluminium, zinc, plated or anodized metal surfaces, and other non-metals like ceramics, wood, paper, glass, and polymer. Laser etching is also useful for thick and thin materials that other methods may not work properly on.
Laser Engraving
By emitting a highly localized laser pulse, the laser engraving method uses a large amount of energy to melt a small material layer. Engraving, like a chisel, makes deep and permanent inscriptions like tracking codes. A laser engraver has a maximum depth of 0.508 mm (0.020″) or 500 microns.
This method is ideal for marking materials frequently subjected to rigorous surface treatments and wear.
Pros and Cons of Laser Engraving
Pros
- Discernible by touch and sight
- Increased resistance to damage and wear
- 3D designs are achievable
- Highly efficient and quick
Cons
- Inefficient with materials due to vaporization
- Limited application range
- Uses more power
- Takes more time
Using Laser Engraving
Laser engraving works best on metals, but other items such as fibreglass, paper, and wood are acceptable, too. You may also prefer laser engraving if you value damage resistance and if you wish to personalise products.
