Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of 3D printing demolding, and particularly relates to an automatic demolding device. BACKGROUND

[0002] A 3D printer is a rapid prototyping machine, which is based on a digital model file, uses a powder-like metal or plastic and other adhesive materials, and obtains a product through layer-by-layer printing. The 3D printer is gradually popularized and applied due to its advantages such as fast manufacturing speed, various materials and good economic benefits. The light solidification forming method is the earliest practical rapid prototyping technology of the 3D printer. A laser with a specific wavelength and intensity is focused on the surface of a light solidification material to make it solidify from point to line and then from line to plane in sequence, thereby completing a layer of drawing work. Then, the lifting platform moves in the vertical direction by the height of a layer, and another layer is solidified. In this way, a three-dimensional entity is formed by layer-by-layer stacking, and a product is obtained.

[0003] At present, when the light solidification forming 3D printer is completed, the formed product is generally manually taken off from the mold. When the formed product is taken off, the bottom of the formed product has a small stress area and uneven stress, which can easily damage the bottom of the formed product, making it a waste product, thereby reducing the product production efficiency. Moreover, manual taking is required, and the whole production efficiency is low.
