Method for producing 3D print fastening piece of three-layer structure from inside to outside

Abstract

A method for producing a 3D print fastening piece of a three-layer structure from inside to outside comprises the specific steps that computer modeling and layer-by-layer cutting are carried out; graphs are converted to light beams carrying graph information, a photosensitive drum is charged to obtain electric potential, and an electrostatic latent image is formed through light beam scanning; the electrostatic latent image passes through a magnetic brush and attracts powder to from an internal component, the surface of the internal component is processed, the steps are executed repeatedly to print the intermediate layer and the outer layer, and the surfaces of the intermediate layer and the outer layer are processed. The 3D print fastening piece made through the method has the advantages of being high in manufacturing precision, long in service life, and good in performance.

Description

technical field [0001] The invention relates to the field of fastener processing, in particular to a method for producing a 3D printed fastener with an inner and outer three-layer structure. Background technique [0002] With the continuous advancement of science and technology in different fields, human beings have made breakthroughs in various fields, and more and more equipment is used. The main purpose of fasteners is to connect various components and play a role in the connection of equipment. It plays a very important role. With more and more equipment, there are more and more types of fasteners. For large quantities of standard fasteners, they can be directly produced in batches, but for small batches of fasteners, equipment batches Production is very wasteful. Since 3D printing can be produced according to the design, more and more fasteners are produced using 3D printing technology. The strength of fasteners produced by 3D technology is often not high. Due to the oc...

[0002] With the continuous advancement of science and technology in different fields, human beings have made breakthroughs in various fields, and more and more equipment is used. The main purpose of fasteners is to connect various components and play a role in the connection of equipment. It plays a very important role. With more and more equipment, there are more and more types of fasteners. For large quantities of standard fasteners, they can be directly produced in batches, but for small batches of fasteners, equipment batches Production is very wasteful. Because 3D printing can be produced according to the design, more and more fasteners are produced using 3D printing technology. The strength of fasteners produced by 3D technology is often not high. Due to the occasions where many characteristic fasteners are used , often special, so traditional 3D printing has been unable to meet its corresponding performance
