FDM mode-based automatic material changing device for 3D printing

Abstract

The invention discloses an FDM mode-based automatic material changing device for 3D printing. The FDM mode-based automatic material changing device for 3D printing comprises a box body; the bottom ofthe inner wall of the box body is fixedly connected with a first motor through a motor fixing plate; the output shaft end of the first motor is fixedly connected with a rotating device; one side of the rotating device is fixedly connected with a turnplate through a rotating shaft; the top of the turnplate is fixedly connected with a gravity sensor; the top of the gravity sensor is vertically and fixedly connected with a material roller supporting frame; one side, near a material roller, of the material roller supporting frame is fixedly connected with a color identification sensor; the tops ofa first rotating frame and a second rotating frame are fixedly connected with feeding cylinders; the two opposite sides of the inner walls of the feeding cylinders are fixedly connected with an infrared transmitting pipe and an infrared receiving pipe correspondingly; and one side of the bottom of the inner wall of the box body is fixedly connected with a locking device. The invention relates tothe technical field of 3D printing. The FDM mode-based automatic material changing device for 3D printing solves the problem that single nozzle can only print one color and can work for a long time without stopping feeding.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an automatic refueling device for 3D printing based on FDM. Background technique [0002] 3D printing 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 is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. In 3D printing, materials of various colors are usually required. Multiple nozzles are completed sequentially, and the manufacturing cost is high. At the same time, there will be a shortage of material during the printing process, which will affect the printing progress. Contents of the inve...
