Have you ever wondered about the differences between laser etching and laser engraving? Although all of the terms are used as if they are similar, they all relate to a different process when it comes to creating images, characters, or drawings on a particular material with a laser. Laser engraving and laser etching Exclusive applications of laser technology with their different requirements and resources.
With this in mind, it’s important to update your terminology and understand the practical and technological benefits of these different laser applications. In this way you can decide which setting you prefer for your next laser project. Below is a list of the main differences that distinguish these laser methods.
Impact on the material
The laser engraving creates a conical drop on the material surface. Laser etching will create a high-contrast marking on the material surface and only evaporates the surface layer of the material.
Laser engraving cuts and evaporates the materials on their way. Effective laser engraving requires the use of high temperature lasers, and recorders often choose the laser power at maximum setting for best results, especially when using a strong material such as anodized aluminum or stainless steel. And laser etching melts the surface. Create a slightly expanded pattern of your choice from warm materials.
Laser engraving is an ideal way to differentiate between parts and objects where high wear is to be expected. When you engrave a jewelry design with a laser, it quickly disappears when the piece is touched repeatedly because the depth is only 0.001 inches. The deep cuts in the laser engraving are good when it comes to creating a permanent marking on a various material. Laser etching is not suitable for safety-relevant parts because the drilling process can damage or damage the excavated structure. Laser engraved markings are less durable and suitable for surfaces with low corrosion.
The processes of Laser engraving and also engraving are very versatile and can be used together with different materials. Laser engraving is best for almost all material that you select, this includes metals, wood, plastic, leather, glass, acrylic and soft materials such as paper. Laser engraving affects the surface of materials, changes the reflection and improves shrinkage. The best materials used for laser etching are stainless steel, anodized aluminum, ceramics, coated metal and polymers. Laser markers are widely used in industry to provide permanent markers without causing material damage.
