Scraper device capable of removing bubbles

Abstract

The invention discloses a scraper device capable of removing bubbles. The scraper device comprises an installing base, an air pipe installing opening is formed in the middle portion of the installing base, a sliding rod is arranged on the inner side of the installing base, a sliding block is arranged on the sliding rod, and a fine tuning nut is further arranged between the sliding block and the installing base; a flow dividing pipe is arranged in the sliding block, a plurality of air sucking pipes are connected to the bottom of the flow dividing pipe, and an elastic soft pipe is connected between the flow dividing pipe and the air pipe installing opening; and a scraper is arranged at the bottom of the sliding block, and a locking nut is arranged at the front end of the sliding block. By means of the scraper device, even adsorption capacity is provided in the resin paving process, the wee air bubbles on the surface of resin can be removed, and the printing quality is improved.

Description

technical field [0001] The invention relates to the field of 3D printing devices, in particular to a scraper device capable of removing air bubbles. Background technique [0002] 3D printer, also known as three-dimensional printer, is a new type of manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses bondable materials such as special wax, powdered metal or plastic. Print layers of adhesive material to create three-dimensional objects. [0003] The material used for photocuring rapid prototyping is liquid photocurable resin, or liquid photosensitive resin, which is mainly composed of oligomers, photoinitiators, and diluents. In the past two years, photosensitive resins are being used in 3D printing emerging industries because of their The excellent characteristics are favored and valued by the industry. The photosensitive resin is in a viscous state. During the process of paving the photosensitive resin, ...

[0003] The material used for photocuring rapid prototyping is liquid photocurable resin, or liquid photosensitive resin, which is mainly composed of oligomers, photoinitiators, and diluents. In the past two years, photosensitive resins are being used in 3D printing emerging industries because of their The excellent characteristics are favored and valued by the industry. The photosensitive resin is in a viscous state. During the process of paving the photosensitive resin, it is easy to cause air bubbles on the surface of the resin layer, thereby reducing the processing accuracy. Laying device that effectively removes air bubbles on the surface of the resin layer
