Metal 3D (three-dimensional) printing device and metal 3D printing method

Abstract

The invention discloses a metal 3D (three-dimensional) printing device and a metal 3D printing method. The printing device comprises a rack system, a heating printing system, a cooling shaping system and an atmosphere control system; the rack system comprises a working table and a spatial three-axis moving component, wherein the working table is used for supporting the other three systems, and the spatial three-axis moving component is used for driving the heating printing system; the heating printing system comprises an electrical heating fire-resistant container; the bottom part of the fire-resistant container communicates with a vertical quartz tube; a dropping liquid hole of which the diameter is less than 0.1 mm is formed in the bottom end of the quartz tube, and an inner cavity of the fire-resistant container communicates with an air pressure component; the cooling shaping system is located below the quartz tube; the heating printing system and the cooling shaping system are arranged in an atmosphere protection chamber of the atmosphere control system. The metal 3D printing device disclosed by the invention is simple in equipment structure and convenient to operate, can be suitable for common metal powder or bulk metals, has high applicability of consumptive materials, can be free of manufacture cost for high-difficulty consumptive materials, and is low in printing cost.

Description

technical field

[0001] The invention relates to a novel metal 3D printing device and a printing method, belonging to the technical field of rapid prototyping of metal materials. Background technique

[0002] 3D printing technology appeared in the mid-1990s, and it is actually a rapid prototyping technology using methods such as layer-by-layer accumulation. As a rapid prototyping technology for emerging materials, 3D printing technology has developed rapidly in recent years. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and other fields.

[0003] The most common 3D printing consumables are plastics (PLA, ABS, etc.), and metal 3D printing technology has also been developed in recent years. In the industry, most of the 3D printing technologies use metal as consumables. At present, industrial...
