Screw type 3D printer capable of replacing outputting material

Abstract

The invention discloses a screw type 3D printer capable of replacing an outputting material, which includes a base, a gate type bracket, a cross beam, a sprayer and a printing platform, wherein the sprayer comprises a cylindrical feeding drum at the upper part and a conical heater at the lower part; a resistance wire is wound on the wall of an inner cavity of the heater; a spray nozzle is arranged at the bottom of the heater; an opening for allowing a stock tank to get into and out of the feeding drum is formed in a drum body of the feeding drum; a screw type stock press fitting mechanism for pressing the stock in the stock tank into the heater is arranged on the cross beam at the top of the feeding drum; the screw stock press fitting mechanism includes an extrusion head, a screw rod and a couple of meshed gears; the screw rod is vertically arranged; the extrusion head is arranged at the bottom of the screw rod; an internal thread of the driven gear is matched with the screw rod; the driving gear is fixedly connected onto an output shaft of a servo motor. With adoption of the screw type 3D printer, the raw material can be replaced on the sprayer directly, convenience and quickness are achieved, the loading auxiliary time is saved, and the working efficiency of the 3D printer is improved.

Description

(1) Technical field: [0001] The invention relates to a printer, in particular to a screw-type 3D printer with replaceable output materials. (2) Background technology: [0002] 3D printer, also known as three-dimensional printer, is a cumulative manufacturing technology that manufactures three-dimensional objects by printing layers of adhesive materials. It is widely used in machine manufacturing, automobile and motorcycle manufacturing, plastic manufacturing, ceramic manufacturing, and medicine. In the beauty industry, toy manufacturing industry, and food processing industry, users can design and output three-dimensional structures in a short period of time, including automobile and motorcycle parts such as engine pistons, various tool wrenches, Eiffel Tower, Statue of Liberty models, etc. [0003] The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. Nowadays, there are various types of media that can be used...

AI Technical Summary

Problems solved by technology

[0004] The feeding system of existing 3D printers is limited to a single raw material, and the entire nozzle needs to be disassembled to replace different materials, which is cumbersome to operate and poor in flexibility
