A 3D printed microwave heating mechanism

Abstract

The invention discloses a 3D-printed microwave heating mechanism. The microwave heating mechanism comprises a 3D-printed rack and a lifting mechanism arranged at the bottom part of an inner cavity ofthe 3D-printed rack; the lifting mechanism is composed of an electric push rod vertically arranged at the bottom end of the 3D-printed rack and a printing platform horizontally installed at the top end of the electric push rod, and two ends of the printing platform are connected to the inner side wall of the 3D-printed rack through clamping blocks in a sliding mode; the inner side wall of the 3D-printed rack is provided with microwave flow guide covers positioned at the top part of the printing platform, and two ends of the microwave flow guide covers are provided with microwave generators with consistent structures; the sides, close to the inner cavity of the 3D-printed rack, of the microwave flow guide covers are embedded with flow guide covers; and tail ends of the flow guide covers areconnected with microwave outlet rings, wherein upper microwave shielding frames are arranged at the top ends of the microwave outlet rings, lower microwave shielding frames are arranged at the bottomends of the microwave outlet rings, and the upper microwave shielding frames and the lower microwave shielding frames are consistent in internal structures. The 3D-printed microwave heating mechanismhas the advantages of being reasonable in structural design and worthy of popularization and application.

Description

technical field [0001] The invention relates to an accessory of a 3D printer, in particular to a microwave heating mechanism for 3D printing, and belongs to the technical field of 3D printing equipment application. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing It is usually realized by a digital technology material printer; it is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology.

AI Technical Summary

Problems solved by technology

[0003] Fused deposition modeling is a process in which a filamentous material such as thermoplastic, wax, or metal is extruded from a heated nozzle and deposited at a fixed rate according to a predetermined trajectory for each layer of the part. Technology is one of the conventional technical means of 3D printing. When using this printing method to print workpieces, the printed end face and end of the workpiece may be cooled rapidly due to the low ambient temperature, which will affect the subsequent printing work.
