Problems solved by technology

This method needs to repeat several cycles, which is very time-consuming, and the accuracy is too low to achieve high-precision printing through eye observation, and further improvement is needed
In addition, when the printing platform is large, it will be very troublesome to manually adjust the printing platform, and it is difficult to achieve the ideal state. It is difficult to adjust the flatness accuracy and horizontal accuracy of the printing platform to reach the allowable error range

Abstract

The invention relates to a 3D (Three Dimensional) printing rack capable of being leveled and belongs to the field of 3D responding auxiliary equipment. The 3D printing rack comprises a rack body, a spraying nozzle mounting seat, a printing base, a spraying nozzle leveling mechanism, a base leveling mechanism and a controller; in the structure, the spraying nozzle mounting seat and the printing base are supported by adopting a multi-point connecting manner and leveling work can be realized through controlling the height of a connecting point; the 3D printing rack has the characteristic of being rapidly leveled; detection of a space inclined angle is realized by utilizing horizon sensors including a gyroscope and the like; and a compensation amount for leveling of the corresponding leveling mechanism is calculated through a mathematical calculation manner, so that the leveling is realized. In a mathematical calculation process, a connecting part is mapped into a coordinate system set by the gyroscope according to a position of the connecting part of the corresponding leveling mechanism and the mounting seat or the base, so that the height adjustment of the corresponding part is carried out according to a ratio.

Description

technical field [0001] The invention relates to a levelable 3D printing frame, which belongs to the field of 3D licensing auxiliary equipment. Background technique [0002] 3D printing technology is a type of rapid prototyping manufacturing technology that has developed rapidly in recent years. It is based on computer technology, through software layered discrete and numerical control molding systems, using high-energy laser beams, hot-melt nozzles, etc. to process metals, ceramic powders, plastics, etc. The manufacturing method of layer-by-layer accumulation and bonding of materials such as cell tissue and cell tissue. At present, the most widely used in the field of 3D printing technology is called fusion deposition molding, that is, FDM method, which mainly transports thermoplastic polymer wires to high-temperature printing heads, melts the wires and continuously extrudes molten polymers, and The part shape is built on the printer base by layer-by-layer accumulation unde...
