Multi-coordinate system collaborative 3D printer

Abstract

The invention provides a multi-coordinate system collaborative 3D printer. The multi-coordinate system collaborative 3D printer comprises a stepping motor, an electromagnetic base plate, a thermal bed, a six-axis mechanical arm, a tray frame, an iron disc and a spray head mechanism; and the spray head mechanism comprises an extrusion material stepping motor, a spray head, a cooling fan, a verticaladjusting mechanism and a horizontal adjusting mechanism. A permanent magnet and an electromagnet are contained in the electromagnetic base plate, and demagnetization and magnetization are controlledby controlling the current flowing through the electromagnet. Compared with an existing 3D printer, the multi-coordinate system collaborative 3D printer has the advantages that the rotation freedom degree of the base plate is increased through the six-degree-of-freedom mechanical arm and the electromagnetic permanent magnet composite device, the three-dimensional solid forming of a planar cube under general conditions can be realized, and flexibly converting in a cartesian coordinate system, a column coordinate system and a spherical coordinate system can be realized, the printing precision of the arc surface and the spherical surface can be improved, and a new idea is provided for printing an arc and spherical surface combination. The equipment operation is simple, the application rangeis wide, and equipment conditions are created for high-precision printing.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a multi-coordinate system cooperative 3D printer. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology, which is based on the STL digital model, and manufactures three-dimensional objects by fusing and depositing bondable materials such as powdered metal or plastic. Compared with the traditional subtractive manufacturing process, the 3D printing process has a higher material utilization rate, and can process products with complex structures according to actual use requirements. [0003] Most of the existing 3D printers are still built in the Cartesian coordinate system, which is characterized by three independent axes. During the printing process, each axis can only move in a straight line, and the macroscopic shaping of the object in the three-dimensional space is completed through the movement of each axis. For products with...

Problems solved by technology

However, when printing a rotating body in space, the deviation of the extrusion nozzle in the coordination of the X and Z axes is still unavoidable

At the same time, this patent is only applicable to the cylindrical coordinate system, and cannot realize multi-coordinate system collaborative printing
