A 3D printing method for large area and large thickness nylon material structure

Abstract

The invention relates to a 3D printing method for a large-area and large-thickness nylon material structure. The 3D printing method comprises the five steps of equipment prefabrication, nylon raw material prefabrication, raw material feeding, forming operation and sizing operation. On one hand, the forming operation efficiency and machining precision of a nylon material workpiece can be effectively improved through 3D printing operation, on the other hand, the defect that gaps and bubbles are prone to producing between layers of nylon materials in the nylon material 3D printing operation can be effectively eliminated, the compactness and structural uniformity of the nylon workpiece material structure are improved, meanwhile the phenomenon of nylon material non-uniform heating in the nylonmaterial forming process due to long 3D printing time and a large area and a thickness of the workpiece is effectively eliminated, and thus the phenomena that the large-area and large-thickness nylonworkpiece is prone to cracking and edge warping are eliminated, and the reliability and stability of nylon workpiece product quality are effectively improved.

Description

technical field [0001] The invention relates to a 3D printing method for a large-area and thick nylon material structure, belonging to the technical field of 3D printing. Background technique [0002] Nylon materials are used in a huge amount in the current 3D printing and molding operations, and nylon workpieces are widely used in production and life. However, in the printing and molding operations of nylon workpieces, as the surface area and thickness of the workpiece increase, On the one hand, it is easy to cause uneven heating in the molding operation of nylon workpieces, which leads to cracking and warping of nylon workpieces. On the other hand, during the molding process of nylon workpieces, 3D printing equipment is spraying layer by layer Each layer of nylon material parts is prone to defects such as gaps and air bubbles, which will cause serious defects in the nylon workpiece product, and eventually lead to the severe impact on the structural strength and toughness o...

[0002] Nylon materials are used in a huge amount in the current 3D printing and molding operations, and nylon workpieces are widely used in production and life. However, in the printing and molding operations of nylon workpieces, as the surface area and thickness of the workpiece increase, On the one hand, it is easy to cause uneven heating in the molding operation of nylon workpieces, which leads to cracking and warping of nylon workpieces. On the other hand, during the molding process of nylon workpieces, 3D printing equipment is spraying layer by layer Each layer of nylon material parts is prone to defects such as gaps and air bubbles, which will cause serious defects in the nylon workpiece product, and eventually lead to the severe impact on the structural strength and toughness of the nylon material of the workpiece, and cause relatively poor quality stability of nylon products Therefore, in response to this problem, it is urgent to develop a new 3D printing method for nylon materials to meet the needs of actual use.
