Problems solved by technology

[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 par...

example 1

[0064] A 3D printing manufacturing method for large-scale parts, the additive manufacturing equipment uses EOS P110, and the supporting software is Magics17.1 and PSW3.6. (1) Use the 3D model of the automobile engine intake manifold provided by the customer according to the customer's requirements. The size of the large-scale parts is 346mm×324mm×192mm, which is larger than the 325mm×250mm×220mm that can be processed by the P110 equipment, so it cannot be completed 3D model processing. (2) The shape of the pipe is complex, and the position of the straight pipe is selected for cutting, and the cutting method of the dovetail groove 5 is adopted, such as Figure 4 shown. (3) Carry out incision processing in Magics, and determine the placement of sub-parts, use RP-Tools to complete the slice production with a thickness of 0.1mm, and set optimized processing parameters in PSW software to ensure its dimensional accuracy. Among them, the spot compensation parameter obtained by the ...

example 2

[0066] Such as Figure 5 As shown, the 3D printing manufacturing of the car dashboard shell, the specific manufacturing steps are similar to Example 1. The incision method adopts a rectangular incision 21 and a zigzag incision 31 in two different parts of the instrument panel shell 11 respectively.

example 3

[0068] Such as Figure 6 As shown, the specific manufacturing steps of the 3D printing manufacturing of large-scale pipes are similar to those of Examples 1 and 2.

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...
