Weight tray of photocuring 3D printer and printing object separation method
2015
The invention provides a weight tray of a photocuring 3D printer. The weight tray is used for bearing a photocuring printing object and comprises a main body and a film coated at one side of the main body, wherein the film is made of a second material different from the first material of the printing object; the first and second materials are chemically nonreactive; the second material can be dissolved in at least one solvent in which the first material cannot be dissolved. Besides, the invention provides a separation method of the weight tray. According to the weight tray and the separation method, the film made of materials other than photosensitive resin coated at the bottom of the main body can be dissolved in at least one solvent, so that the printing object can be smoothly separated from the main body; after the printing object is simply washed, an integral product with a smooth surface can be acquired; the formation yield of printing objects can be greatly improved; the main body is unlikely to get damaged and can be repeatedly used for multiple times and the printing cost is saved.
