CO2 laser machines are not suitable for directly engraving or cutting highly reflective materials like metal or mirrored surfaces. The laser beam reflects off these materials, potentially causing damage to the machine or affecting the quality of the engraving. Coating the surface or using specialized techniques may be required for engraving or cutting reflective materials.

The lifespan of a CO2 laser machine can vary depending on factors such as usage, maintenance, and the quality of the machine. With proper care, routine maintenance, and regular tube replacements (if applicable), a well-maintained CO2 laser machine can last several years of active use.

It is generally not recommended to use a CO2 laser machine to engrave or cut food items due to potential safety and hygiene concerns. Contaminants from the materials being processed may be transferred to the food, making it unsafe for consumption.

CO2 laser machines are primarily designed for flat or slightly curved surfaces. Engraving on highly curved or irregular surfaces may require specialized fixtures, jigs, or rotary attachments to ensure consistent engraving depth and quality.

CO2 laser machines can engrave or cut PVC or vinyl materials. However, it’s important to note that the process may release chlorine gas, which is harmful to the machine and operators. Proper ventilation and safety precautions should be taken when working with PVC or vinyl materials.
