Abstract

The invention relates to a three-dimensional printing forming product, a manufacturing method of the three-dimensional printing forming product and a supporting jig. The manufacturing method of the three-dimensional printing forming product comprises the steps that a first water-soluble material is adopted for printing a supporting layer; a target product is printed on the supporting layer by adopting a forming material; and a covering layer is printed on the target product by adopting a second water-soluble material so as to cover the surface of the target product. According to the manufacturing method of the three-dimensional printing forming product, on the premise of not additionally increasing the subsequent processing procedure, the surface roughness is reduced, the surface smoothness is improved, and the manufacturing method is particularly suitable for products with small thicknesses; on one hand, the product indexes such as wear resistance, clearance fit connection strength, fatigue strength and contact rigidity are improved; on the other hand, stacking matching is facilitated, the tight position relation is achieved, and the stability of the final product structure is improved; and on the other hand, the model cost expenditure is reduced, the processing time is shortened, and the high cost caused by product design change, mold repairing and mold opening in the new product development stage is reduced.

Description

technical field [0001] The present application relates to the field of three-dimensional printing, in particular to a three-dimensional printing molding product, a manufacturing method thereof, and a supporting jig. Background technique [0002] Three-dimensional printing is 3D printing. Because layers are stacked, it is easy to have layers on the surface of the newly printed finished product, regardless of fused deposition modeling (FDM), stereolithography (SLA), digital light processing (DLP) or selective laser. This problem exists in various traditional 3D printing technologies such as fusion molding (SLM). [0003] This surface phenomenon generally increases the subsequent treatment process by smoothing the surface of the component to make the surface smooth and flat. However, the post-processing process will increase the processing steps, increase the cost and prolong the development time. [0004] Take the 3D-printed thin shell product as an example. There is an enti...
