3D Printer ANYCUBIC Photon Mono 4K Purchased in January 2022, and used without any problems until I upgraded to a higher-end model last month. The resin vat has been replaced with a metal one from Mars 2, and n-FEP film from SK Honpo is installed. An FDM-made stay is attached, allowing the cover to be temporarily placed on top of the main unit. It will be shipped in the original box. Please note that this is a used item and is sold as-is, with no claims or returns accepted.
