Apparatus and method for polishing three-dimensional printed plastic/resin pieces

Abstract

The invention provides an apparatus for polishing three-dimensional printed plastic / resin pieces. The apparatus comprises a polishing chamber and a solvent storage tank which are communicated with each other by use of a liquid inlet pipe; the apparatus is characterized in that the polishing chamber is an airtight container, an exhaust opening of the polishing chamber is connected with an air inlet of a vacuum device, an air outlet of the vacuum device is connected to the outside atmosphere and the solvent storage tank, respectively, and a switch is used for controlling the vacuum device to be connected with or disconnected from the polishing chamber, the solvent storage tank and the outside atmosphere, respectively. The apparatus for polishing the three-dimensional printed plastic / resin pieces is environmentally-friendly, capable of effectively polishing to-be-polished pieces with complex structures, and also capable of quickly recovering the hardness of the polished pieces.

Description

technical field [0001] The invention relates to a polishing device, in particular to a device for polishing the surface of plastic and resin parts printed by a three-dimensional printer. Background technique [0002] At present, 3D printing technology has developed rapidly, and everyone is trying to apply 3D printing technology in various fields. 3D printing technology uses 3D printers to position and inject thermoplastic materials layer by layer on a fixed spatial position using thermoplastic materials, precise hardware and software positioning technology, and thermoplastic materials are quickly shaped and adhered to form finished products of fixed size. Because the 3D axis of 3D printing can achieve the command position in the 3D drawing extremely accurately through the control of software, 3D printing technology can easily and cheaply produce parts with complex shapes and small quantities that require precision. [0003] However, whether 3D printing is for industrial app...

Problems solved by technology

It is not suitable to buy, not to mention, it will seriously pollute the indoor environment when used indoors

It simply cannot meet many uses with high environmental requirements

In addition, due to insufficient gas exchange, the existing technology is difficult to polish the internal surface of a complex small cavity (similar to the inner wall of a "vase" object)
