Abstract

The invention discloses 3D printing equipment with a printing head embedded into a printing liquid, and relates to the field of 3D printing. The 3D printing equipment solves the problem that an existing 3D printing technology is not easy to print in complex, hollow and fine shapes. The 3D printing equipment is composed of a spraying head embedded type printing device and a cooling device, whereinthe spraying head embedded type printing device is arranged at the circle center of the cooling device. The 3D printing equipment with the printing head embedded into the printing liquid has the characteristics of simple in structure, reasonable in design; the printing of a complex hollowed-out material without supporting materials is realized, meanwhile, the cross-interface 3D printing can be realized which is not easy to achieve in an existing equipment, that is several mutual connection materials with different types or performance can be printed at one time; the equipment can adapt to various types of printing liquid as long as the printing material is thermosetting resin.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing device in which a printing nozzle is embedded in a printing liquid. Background technique [0002] At present, 3D printing technology uses computers to carry out three-dimensional digital design. By using 3D printing equipment to superimpose "printing materials" layer by layer, the digital model in the computer is finally turned into a real object. 3D printing equipment can be filled with "printing materials" with different characteristics such as metals, ceramics, plastics, and resins. In industries related to art design, such as industrial design, fashion design, jewelry design, furniture design, display design, artwork protection and restoration, 3D printing has the characteristics of unlimited design space, unlimited combination of materials, and accurate physical reproduction. The perfect combination of art and technology has produced many amazing artworks and produc...
