3D printing manufacturing method for large-size part

Abstract

The invention discloses a 3D printing manufacturing method for a large-size part, which comprises the following steps: a) cutting a model of a to-be-manufactured large-size part into a plurality of sub-part models in a preset size scope; b) manufacturing and finishing the processing and forming of all sub-parts by adding materials on the basis of the sub-part models; c) jointing and fixing all the sub-parts, thereby forming the large-size part. According to the invention, the 3D printing device in insufficient effective processing size can be used for manufacturing the large-size part, the property and the whole size precision of the large-size part after being cut and spliced can be ensured, and a quick and efficient solution is supplied to the manufacturing of the sample or end product of the large-size parts in various fields.

Description

technical field [0001] The invention relates to the technical field of processing large-size parts, in particular to a 3D printing manufacturing method for large-size parts. Background technique [0002] There are large-sized parts in many fields. The traditional manufacturing method is to manufacture them through large-scale processing equipment or split them into multiple components during design, and the process is all subtractive manufacturing. The base materials are mainly plastics and metals. Etc., the large-size parts processed by the traditional subtractive manufacturing method are limited by large-scale equipment, or the designer's freedom to design the parts in the early stage is limited. The method of additive manufacturing breaks the limitation of the structural form of parts in traditional design, and can meet the processing requirements of any shape and size. However, due to the limitation of 3D printing technology, it is currently impossible to manufacture par...

[0002] There are large-sized parts in many fields. The traditional manufacturing method is to manufacture them through large-scale processing equipment or split them into multiple components during design, and the process is all subtractive manufacturing. The base materials are mainly plastics and metals. etc. Traditionally, large-sized parts processed by subtractive manufacturing methods are limited by large-scale equipment, or the designer's freedom to design parts in the early stage is limited.

The method of additive manufacturing breaks the limitation of the structural form of parts in traditional design, and can meet the processing requirements of any shape and size. However, due to the limitation of 3D printing technology, it is currently impossible to manufacture parts that meet the direct molding requirements of various large-size parts. equipment, which also limits the manufacture of large-scale components in various fields
