Laser engraving is a precise method of marking or engraving a workpiece, with advantages such as accuracy and versatility, but high equipment costs. It can be used for industrial or artistic purposes on various materials, including stone, glass, metal, and plastic. The hardware typically includes a laser, workspace, and interface, with different types of equipment for different applications.
Laser engraving is the process of using a laser to engrave or mark the surface of a workpiece. Compared to other engraving methods, laser engraving is often considered to have many advantages, although it also has some disadvantages. For example, it can be highly accurate, but equipment costs are often prohibitive. This technology can be useful for many applications and can use many materials. Engraving methods vary depending on the type of work piece and material, which means that different engraving equipment is sometimes required.
The uses for laser engraving are usually based on producing a specific design. The type of design often determines its use. Professional engraving can include the industrial or commercial production of engraved products. These can include duplicate images or custom images in almost any image quality, although high quality engraving is often more expensive than low quality engraving. Partly due to the wide range of materials that can be used, engraving can also be used for artistic work.
Stone, glass, metal, plastic and natural materials can all benefit from laser engraving. Indeed, for some of these materials, such as stone and metal, engraving can be the primary form of marking for any purpose. Harder materials such as stone and glass are often difficult to engrave using other forms of engraving. For example, laser engraving of crystals relies heavily on the use of lasers to create images within hard, crystalline material. The variety of materials used means that there are many different types of engraving.
Industrial engraving, for example, might use large machines to mass-produce a single laser engraved product or design. Professional engraving, on the other hand, might rely on small machines to tailor products to consumers’ needs. Despite these differences, the hardware used in laser engraving is often similar.
The hardware used in laser engraving often consists of three main parts: the laser, the workspace and the interface. Lasers can be built in many ways and some machines might have complex lasers while others rely on simple lasers. The workspace often depends on the type of laser used. For example, simple engraving equipment might have a flat table for the work piece, while complex engraving equipment might hold and move the work piece in multiple axes. The interface of these systems is usually a computer into which specific designs are entered and through which engraving commands are executed.
