Material compatibility
Portable laser engravers often have more limited material compatibility. Due to its compact design and low-power characteristics, portable laser engraving machines are usually suitable for materials that are easier to process, such as wood, leather, paper, soft plastics,metal, etc. These materials are relatively soft and require low energy from the laser, making them suitable for processing by portable laser engraving machines.
Desktop laser engravers typically have wider material compatibility. Desktop-level laser engraving machines can usually replace the laser, and can select a suitable laser according to the material to be engraved, so they can process more types of materials, including some materials with higher hardness, such as metal, glass, stone, etc., as well as composite materials. The processing range and compatibility of materials can be greatly improved.
