It is possible for uv printer to print mini metal shell, but it should be noted that the printing height of UV printing is about 10cm, depending on the manufacturer's equipment. Generally speaking, 10cm is the best printing height. Therefore, I suggest that you can find a uv printer manufacturer for credit information. Determines whether it can be printed.
If you need uv printer equipment, you can consider Toshiba uv printer, which adopts industrial Toshiba nozzle with very high cost performance, and the printing speed is twice that of Epson, the printing accuracy is higher than that of Ricoh G5, and the service life is 24 months to 36 months. There is also a two-year warranty.
