3D printer for precision casting

Abstract

The invention discloses a 3D printer for precision casting. The 3D printer comprises a box body, wherein an opening is formed in the front end of the box body and an observation window is mounted on the opening in a covering manner; a storage box is fixedly mounted at the top of the box body; a base is fixedly mounted at the bottom of the inner side of the box body; two front-back sliding seats are fixedly mounted at the top of the base and symmetrically distributed at two ends of the top of the base; up-down sliding seats are slidably mounted in the front-back sliding seats in the front-backdirection; a printing sliding seat is horizontally arranged right above the base; two ends of the printing sliding seat correspond to the up-down sliding seats which are slidably mounted on the two ends of the printing sliding seat; a sliding groove is transversely formed in the printing sliding seat and a printing head seat is slidably mounted on the printing sliding seat; a conveying head is arranged at the top of the printing head seat; a rotating disc is rotatably mounted at the bottom of the printing head seat through a rotating shaft; four printing nozzles are arranged at the bottom of the rotating disc and uniformly distributed at the bottom of the rotating disc; and supporting rods are fixedly mounted at the top of the rotating disc.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a precision casting 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. 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. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0003] When the existing pr...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a precision casting 3D printer, which can use the corresponding printing nozzle to perform printing conversion when different materials are required for different parts of the printed product, and avoid using a single printing nozzle to perform different material conversion. , the print nozzle is contaminated by residual materials, resulting in insufficient yield of printed parts
