When combined with the protective enclosure, it is safe for home studios, retail stores, and maker spaces, making it ideal for daily tumbler engraving. The LP5 is excellent for professional workshops that produce large quantities and want to create both surface and deep engravings on metal tumblers. However, fiber lasers like the LP5 require more setup knowledge and a higher initial budget, which may be overkill for casual users. Type 4: CO₂ Laser Engraving Machine CO₂ lasers are best suited for coated tumblers or plastics. They do not work on uncoated metal, as the laser cannot mark the surface without a coating. Therefore, I do not recommend CO₂ laser devices as a first choice for engraving metal tumblers. However, CO₂ laser engraving itself can still be used for certain tumbler applications. If the tumbler has a plastic shell, an acrylic surface, or a painted/powder-coated metal exterior, a CO₂ laser can produce clean and clearly visible engraving results. For bare metal tumblers or projects requiring fine details and long-term durability, diode, IR, and fiber lasers are generally the better and more reliable choice.
