Combined type three-dimensional forming machine and printing module thereof

Abstract

The invention discloses a combined type three-dimensional forming machine and a printing module thereof. The combined type three-dimensional forming machine mainly comprises a construction platform, aconstruction displacement platform and the printing module, wherein the construction platform is provided with a feeding groove and a forming groove; the feeding groove and the forming groove are used for accommodating a construction material and a three-dimensional forming object correspondingly; the construction displacement platform is erected on the construction platform to generate relativedisplacement; the printing module is erected on the construction displacement platform and comprises a rolling shaft, a first jet printing module and a second jet printing module; and the constructiondisplacement platform drives the rolling shaft to push the construction material into the forming groove, jet spraying of a first jet printing material and a second jet printing material onto the construction material in the forming groove through the first jet printing module and the second jet printing module correspondingly is carried out in a layer-by-layer stacking manner, and therefore thethree-dimensional forming object is formed.

Description

【Technical field】 [0001] The invention relates to a composite three-dimensional molding machine, especially a three-dimensional molding machine capable of jet printing multiple kinds of adhesives at the same time. 【Background technique】 [0002] Three-dimensional prototyping technology, also known as Rapid Prototyping (RP) technology, because rapid prototyping technology is automatic, direct and fast, it can accurately transform design ideas into prototypes with certain functions or can manufacture directly used parts or finished products , so that the product design can be quickly evaluated, modified and functionally tested, greatly shortening the product development cycle, thus making 3D printing technology widely favored. [0003] Today's 3D printing molding technology is in a stage of vigorous development, and the rapid prototyping technologies used are also different. The rapid prototyping technologies currently used in the industry mainly include the following technolo...

AI Technical Summary

Problems solved by technology

[0007] The main purpose of the present invention is to solve the problem that the known powder three-dimensional molding machine can only be used for a single or the same type of adhesive, and cannot use multiple different adhesives on the printing powder at the same time. Different types of adhesives are used for changing or special structural strength requirements, so that the molding material is single and cannot be changed according to the demand

[0008] Another object of the present invention is to solve the problem that in the known powder three-dimensional molding process, it is necessary to use support materials to assist printing, which makes the printing process cumbersome and complicated, and it is time-consuming and inconvenient to remove the support materials when the printing is completed.
