Engraving is a technique that has been used for centuries to process or decorate objects. Traditional engraving methods mainly use tools to physically cut into the surface of the material, mostly by hand. In the 1960s, laser engraving was introduced. Laser engraving processing is a material processing technology based on the use of CNC technology and a laser as the processing medium. The physical denaturation of the processing material by instantaneous melting and vaporization under laser engraving irradiation enables laser engraving to achieve the purpose of processing and provides an innovative engraving method with several advantages compared to traditional mechanical engraving technology.
Speed and accuracy
Laser engraving is much faster than traditional engraving, which requires physically moving the tool over the material. Laser engraving is also very precise, allowing for narrow line widths and high resolution marks. It can engrave intricate designs, patterns, and even photographs. In contrast, traditional chisel and stone engraving is difficult to achieve with precision and finesse.
Low setup and cost
Laser engraving requires only that the design be loaded into the laser engraver software. The software then converts the design into a signal that instructs the laser engraver to engrave according to the designed pattern. Laser engraving machines are also less expensive than some traditional engraving equipment, especially when the cost of skilled labor is considered.
Marking various materials
Lasers can engrave not only metal but also wood, glass, plastic, coated metal, etc. With the right laser setup, laser engraving machines are more widely used in various industries. On the other hand, traditional engraving is usually only available for some specific materials.
In summary, while traditional engraving has a long and respected history, laser engraving offers significant advantages in speed, accuracy, ease of use, and material versatility. For most industrial and commercial needs, laser engraving has become the dominant engraving technique and has replaced traditional mechanical engraving methods in many applications. However, traditional craft engraving still produces the handcrafted effects that many people appreciate in select decorative pieces. For specific needs and aesthetics, traditional engraving is still the ideal choice.
