Problems solved by technology

The traditional 3D printer is a dot printing fixed direct extrusion type. When the model is printed, it needs to use slicing software to slice the model; but the side convex part of the sliced ​​figure needs to be printed with a bracket as the support of the side convex part (such as the handshake of the water cup). This printing method will inadvertently prolong the printing time and waste printing consumables, and some single-nozzle printers use the same printing material as a support, and it is difficult to separate the finished product from the support after printing, and even cause damage to the printed finished product

Abstract

The invention discloses a rotating nozzle device, a 3D printer and a printing method. The rotating nozzle device comprises a supporting shaft, a rotating shaft and a nozzle. The supporting shaft is mounted at the bottom of the body of the 3D printer. One end of the rotating shaft is connected with the supporting shaft through a rotating joint, and the other end of the rotating shaft is provided with the nozzle. A driver and a sensor are arranged inside the rotating joint. The sensor is connected with a processor and the driver of the 3D printer. The driver is connected with the rotating joint. According to the rotating nozzle device, the 3D printer and the printing method, the traditional morphological structure of the printing nozzle is broken through, and the problem that the side protruding part of a printed model needs to be supported is solved; printing materials are reduced, printing efficiency is improved, and the integrity of the finally-printed model is guaranteed; convenience is brought to switching of the nozzle directions in the printing process, and the flexibility of the rotating nozzle for printing the 3D model is improved.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a rotary nozzle device, a 3D printer and a printing method. Background technique [0002] With the era of modern scientific and technological progress, the printing technology of 3D printers has entered an era of rapid development. 3D printers are involved in a wide range of fields, including industrial manufacturing, medical and health fields, and modern scientific research models. Many research fields are at the forefront of the world. The traditional 3D printer is a dot printing fixed direct extrusion type. When the model is printed, it needs to use slicing software to slice the model; but the side convex part of the sliced ​​figure needs to be printed with a bracket as the support of the side convex part (such as the handshake of the water cup). This printing method will inadvertently prolong the printing time and waste printing consumables, and some single-nozzle printers use the ...
