3D printer

Abstract

The invention relates to the field of printers, in particular to a 3D printer. The 3D printer comprises a printer body and an objective table arranged on the printer body, wherein a printing device is arranged on the printer body and comprises a feeding device, a first-level extrusion device connected with the feeding device, a driving device arranged on the first-level extrusion device and a second-level extrusion device; the second-level extrusion device is arranged at the other end, connected with one end of the driving device, of the first-level extrusion device, and a printing nozzle is arranged on the other end, connected with the first-level extrusion device, of the second-level extrusion device; a lifting device capable of prompting reciprocating lift of the objective table is arranged on the printer body, and a moving device capable of enabling the printing device to transversely and longitudinally move back and forth is arranged on the printing device. The 3D printer has the advantages of being simple in structure, small in occupied area, low in failure rate, low in energy consumption, high in printing efficiency and precise in positioning.

Description

technical field [0001] The invention relates to the field of printers, in particular to a 3D printer. Background technique [0002] With the development of printer technology, 3D printers capable of printing three-dimensional objects are gradually emerging. Traditional inkjet printers spray ink onto paper and other carriers to display a two-dimensional image. 3D printers do not rely on ink to display, but rely on real raw materials such as plastics and metals. Generally, 3D printers heat and soften raw materials and spray them to specific areas through printing nozzles. Then, after receiving a series of digital slices made by a computer, the 3D printer stacks successive thin layers until a three-dimensional solid object is formed. It can be seen that 3D printers can directly print shaped products, thus providing a new manufacturing method.

AI Technical Summary

Problems solved by technology

[0003] The extruded printing consumables of the prior art printers have complex extrusion structure and large volume. After passing through the intermediate transmission link, the transmission efficiency is low and the energy consumption is high. It is easy to cause failure or even damage to the motor and transmission mechanism, which affects the service life of the printer. The extruded part sometimes slips , The reliability of consumables transmission is poor, resulting in quality problems or even substandard products in printed products, resulting in waste of production and high production costs

[0004] Moreover, the printing workbench usually moves up and down, left and right, and forward and backward by setting x, y, and z motion modules on the printing workbench. This structure is relatively complicated and has a large volume. , suitable for larger printers, for some smaller printers, this structure is likely to cause failure or inaccurate positioning due to its complex structure
