Abstract

The present invention is applicable to the technical field of three-dimensional printing, and provides a sealing device, a three-dimensional printer equipped with the sealing device and a printing method thereof. The sealing device is applied to a three-dimensional printer, and the three-dimensional printer includes a printing head for printing parts , the sealing device includes a base installed in the part processing area, a flexible sealing cover set on the base and forming a closed cavity with the base, and a workbench for carrying parts to be processed. The printing head is inserted into the flexible sealing cover to seal with the flexible The cover is sealed and connected, and the base is provided with an air inlet passage for filling the airtight cavity with protective gas and an air outlet passage for discharging the protective gas. The three-dimensional printer provided by the present invention adopts a flexible airtight cavity, which can better adapt to the movement of the axis in the printing process; at the same time, it adopts a modular design, and the flexible airtight cavity device and the printer body are relatively independent, and can also be applied to other similar functions occasions.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional printing, and in particular relates to a sealing device, a three-dimensional printer equipped with the sealing device and a printing method thereof. Background technique [0002] In three-dimensional (3-Dimensional, 3D for short) printing and processing, it is necessary to form a closed cavity, and fill the cavity with protective gases such as inert gas to prevent oxidation of high-temperature parts during printing or processing. The processing environment is temperature controlled. [0003] In the 3D printing of the powder spreading type, a closed cavity is usually designed in the 3D printing equipment, and actions such as powder spreading, printing and processing are performed in the closed cavity, and at the same time, the corresponding devices are placed in the closed cavity . In this type of 3D printing equipment, since more devices and equipment are arranged in the airtight cavit...
