Laser engraver
Based on computer numerical control (CNC) technology, laser engraving works by selectively machining the surface of a material with a laser beam based on a pattern output by a computer. The image will then appear on the surface of the material. It differs from laser marking and etching in five ways:
1. According to the material surface and the amount of removal, laser engraving can be divided into etching, laser ablation and deep laser engraving.
2. This can engrave various materials such as plastic, leather, metal, glass, etc.
3. Best for personalization and customization.
4. This is the fastest way of laser marking.
5. Do not touch the surface of the material during the engraving process.
(ps:Here we recommend a cost-effective laser engraving machine that can also be used by families and individuals, the sculpfun s10 laser engraver, which can basically meet the needs of small businesses or DIY creators)

laser marking machine
As one of the most extensive application fields of laser technology, laser marking machine is mainly used in advertising industry, construction industry and sign making industry. During this process, a laser beam acts on the surface of the material, subtly and permanently changing its appearance. From millimeter level to micrometer level, laser marking can process various characters, symbols and patterns, which play an important role in anti-counterfeiting systems. It differs from laser engraving and laser etching in the following 4 ways:
1. It includes annealing, carbon migration, foaming and coloring.
2. It is less common than laser engraving or etching.
3. Usually used in medical equipment industry.
4. It is ideal for marking logos, barcodes, UID codes and other identifying objects.

Laser Etching Machine
A subset of laser engraving, laser etching is the process by which the heat generated by a laser beam melts the surface of a material. This heat has a very high temperature and causes the material to trace, no more than 0.001 inches deep. It differs from laser engraving and marking in the following ways:
1. It can change the reflectivity of the material and enhance the contrast between marked and unmarked areas.
2. Compared with laser engraving and marking, the productivity is lower and not suitable for mass production.
3. Although these three types of laser technologies have their own advantages and disadvantages in processing materials, they are all essential to modern industry and society.
