Laser Engraving is the practice of using a laser to engrave an object whereas Laser Marking covers a broader category of methods to mark an object, which might include color changes, charring, foaming, melting and ablation.
Types of laser engraving include laser deep engraving, three-dimensional laser engraving, micro engraving, smoothing and frosting:
- Deep Engraving - In deep laser engraving, deep markings are made through repeated removal of material layers.
- 3D Engraving - three-dimensional laser engraving involves three-dimensional, layer-wise material removal which is executed depending on the component geometry. This process can also be used to engrave complex products such as minting dies or embossing stamps and tools.
- Micro Engraving - micro laser engraving is used if tools used for minting coins or for manufacturing jewelry need to be marked with fine filigree structures.
- Laser Smoothing - to improve the surface quality and a longer lifetimes of tools, areas that are previously three-dimensionally engraved can be smoothened using a laser.
- Matting - laser matting or “frosting” involves direct materials processing of the end product or the embossing tool to achieve optical effects.
