Automatic post-processing method for light-cured 3D printer and device

Abstract

The invention relates to an automatic post-processing method for a light-cured 3D printer and a device. The automatic post-processing method for the light-cured 3D printer comprises the following steps of after finishing printing of a shaped product, moving the shaped product to a first preset position; after reaching a preset standing time, moving the shaped product into a cleaning cavity, and cleaning the shaped product; and after reaching a preset cleaning time, moving the shaped product to a second preset position, and air drying or curing the shaped product. According to the automatic post-processing method for the light-cured 3D printer and the device, cleaning and air drying of the shaped product are finished in the printer without causing environmental pollution, the printed shaped product is ensured to be clean without pollution and can be directly taken out and used, and the light-cured 3D printer easily comes to the masses.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an automatic post-processing method and device for a photocuring 3D printer. Background technique [0002] With the continuous development of science and technology, the application of 3D printers (three-dimensional printers) is becoming more and more extensive. Existing light-curing 3D printers need to do the following steps to complete the model printing work after the printing is completed: wait for a period of time, and the model can only be taken out after the liquid material bonded to the model dries up naturally; Liquid-like cleaning (ultrasonic or manual cleaning with a brush); removal of support; re-curing and aging. This photocuring 3D printer has the following problems: [0003] 1. Liquid molding materials are chemical products and should not be directly contacted by people, especially children. In addition, the gas produced by the volatilization of such material...

AI Technical Summary

Problems solved by technology

[0003] 1. Liquid molding materials are chemical products and should not be directly contacted by people, especially children. In addition, the gas produced by the volatilization of such materials is also harmful to human body, so it is necessary to wear rubber gloves and masks;

[0004] 2. Due to the solvent-like liquids (such as: alcohol, toluene, butyl ester and other synthetic solvents, etc.), there are strict requirements on the working environment, good ventilation is required, open flames are prohibited, and other factors are not suitable for this type of product to be popularized and household;

[0005] 3. The work surface needs to be cleaned for a long time for the residues of molding materials that have been accidentally dripped, and the process is cumbersome and complicated;

[0006] 4. Solvent residues (chemical products) need to be collected manually before processing

[0007] In general, the existing light-curing 3D printers are not conducive to their comprehensive promotion due to the processing of materials and molded products, and they have entered the public
