Problems solved by technology

At this stage, analyzing the printer from the mechanical level can achieve higher speed movement, but when printing with FDM technology, the cooling and solidification time of the material must be considered, and the printing speed is relatively low.

Embodiment Construction

[0020] First of all, it must be pointed out that this embodiment is only used to further illustrate the present invention, and should not be construed as limiting the protection scope of the present invention.

[0021] The printer 8 is connected with the spiral material extruding mechanism 1, and printing starts, and the nozzle of the printer and the heating device 4 start to work, and the nozzle of the printer and the nozzle of the heating device 4 are heated to a certain temperature to ensure that the printing material 3 melts when entering the nozzle. After the temperature of the nozzle is heated to a predetermined temperature, the spiral material extruding mechanism 1 starts to work to extrude the printing material 3 from the material box 2 and squeeze the printing material 3 into the printer nozzle and the heating device 4 . The printing material 3 melts in the printing head, and at the same time, the printing head moves on the XY plane to extrude the printing material 3 o...

Abstract

The invention discloses a high-speed 3D printer with a cooling system. The high-speed 3D printer comprises two core systems including the cooling system and a rapid wire discharging system, wherein the cooling system is connected with the rapid line discharging system; and the rapid three-dimensional printing can be realized. The high-speed 3D printer has the contents that by utilizing the coolingsystem, a printed material can be rapidly cooled and condensed and can be combined with preceding printed materials; an extrusion mechanism adopts a spiral wire feeding mechanism, so that the wire feeding speed and uniformity are guaranteed; and meanwhile, the heating temperature of a spray head is relatively high, the fluidity of the material is improved, and the extrusion speed of the materialis further increased. Finally, the printing efficiency is improved, and the operation efficiency of the printer is liberated.

Description

technical field [0001] The invention relates to a high-speed FDM 3D printing device, which can quickly print out three-dimensional entities. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using various adhesive materials to construct objects by layer-by-layer printing. The biggest feature of 3D printing technology is personalization and customization. With this technology, people can print arbitrarily complex shapes without being limited by the inability to machine them. This technology was first applied to mold manufacturing, and then gradually applied to direct manufacturing of some products. With the emergence of 3D printing technology, there are many ways to realize three-dimensional printing, such as Stereo Lithography Appearance (SLA), which is the earliest rapid prototyping manufacturing process or the earliest 3D printing technology. FDM (FusedDeposition Modeling) process Fus...
