Abstract

The invention discloses a 3D (Three Dimensional) printing machine with a material recycling and planting cleaning device. The 3D printing machine is provided with a crushing device; a crushing rolleris provided with crushing teeth and can be used for crushing waste materials with a relatively great grain diameter; the 3D printing machine is provided with a smashing device, the smashing device isinternally provided with a spiral tapered saw tooth crushing cutter for effectively crushing the waste materials and conveying the waste materials into a melting cavity; a fuse wire strong-wind cooleris arranged and is used for effectively cooling a fuse wire and conveying the cooled wire into a wire winding device; the recycled waste materials can be directly collected and stored by the wire winding device and also can be directly used as raw materials of the printing machine to be input. The 3D printing machine is provided with double printing heads; a printing spraying nozzle adopts doublefeeding openings and each feeding opening is provided with an electronic control valve; the feeding openings can be automatically switched to realize rapid material exchange; a printing platform cleaning device is arranged and can be used for automatically cleaning a printing platform; the cleaned waste materials are directly conveyed into the crushing device and the printing efficiency is accelerated. By adopting the 3D printing machine disclosed by the invention, the recycling and reutilization of the 3D printing waste materials are realized, the utilization rate of the raw materials is improved and the material waste problem is effectively solved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer with waste recycling and platform cleaning devices. Background technique [0002] 3D printer is a rapid prototyping device. Through slicing software, the three-dimensional model is converted into printing parameters, and materials such as plastic or metal powder are used to realize rapid and accurate prototyping of complex models, reducing the time required for product design and avoiding The increase in time and cost caused by repeated mold opening greatly shortens the product development cycle. This technology is being widely used in scientific research and daily life. [0003] At present, most of the existing 3D printers on the market are mainly small fused deposition types, and the raw materials used are mostly ABS, PLA, etc. During the printing process, usually due to parameters and environmental problems, the printed model does not meet the requirements, ...
