3D printer high in working efficiency and capable of saving materials

Abstract

The invention relates to a 3D printer high in working efficiency and capable of saving materials. The 3D printer comprises a material recycling device, a top plate, a hopper, a material conveying device, a material conveying pipe, a spray nozzle, a transverse-movement device and two lifting units. The two lifting units are arranged on the two ends of the material recycling device correspondingly. The top plate is erected on the two lifting units. The transverse-movement device is arranged between the two lifting units. The lifting units are in transmission connection with the transverse-movement device. The spray nozzle is arranged under the transverse-movement device. According to the 3D printer high in working efficiency and capable of saving the materials, quantitative powder is provided through the material conveying device for printing of the spray nozzle, due the simple internal structure, the equipment cost is reduced, meanwhile, the conveying efficiency is improved, and the printing efficiency is guaranteed. Besides, a working platform is made to incline through a turnover device inside the material recycling device, residual raw materials are reserved into material collecting boxes inside a box body, and accordingly the raw materials are recycled conveniently and utilized circularly.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printer with high working efficiency and material saving. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. Layers of bonded material are used to create three-dimensional objects. At this stage, 3D printers are used to manufacture products. Objects are constructed by printing layer by layer, and data and raw materials are put into the 3D printer. The machine will manufacture products layer by layer according to the program.

Problems solved by technology

[0003] For 3D printers that use powdered metal as raw material, when the nozzle is printing, it is necessary to continuously provide a quantitative amount of material to the nozzle. In the existing printer, the calculation is performed through precision instruments and equipment, and then the material is delivered through the transmission device. Although It meets the printing needs, but due to the high cost of the instrument and the need for quantitative calculation processing at the same time, the work efficiency is low, which affects the printing efficiency of the 3D printer. Not only that, after the printing is completed, there are usually some metal raw materials left on the working platform Powder, although these metal powders can be recycled and reused, people have not paid enough attention to them. Usually, these metal powder raw materials are wiped off while wiping the working platform, which causes a waste of raw materials and is not conducive to the repeated recycling of resources.
