When selecting a personalized gift machine (such as laser engravers, UV printers, or 3D sublimation heat presses), you must prioritize positioning accuracy (ideally ±0.01mm) and software compatibility. Ensure the machine supports common design formats like AI, DXF, and PLT. For laser-based machines, verify the laser tube lifespan (e.g., 10,000 hours for CO2 tubes) and the cooling system efficiency. For vending-style gift machines, check the PLC control system stability and the touchscreen responsiveness to ensure a smooth user interface.
