Abstract

The invention discloses a 3D printer sprayer with a rotation switching function in order to solve the problem that a 3D printer is low in printing efficiency and troublesome in replacing of a spray nozzle of an extruder. The 3D printer sprayer comprises a fixed seat (1), a heating bar (2), a thermocouple (3), a threaded stop ring (4), spray nozzles and a rotating seat (6). The spray nozzles comprise the first spray nozzle (5), the second spray nozzle, the third spray nozzle and the fourth spray nozzle. The heating bar (2) and the thermocouple (3) are installed in a heating bar installing hole (13) and a thermocouple installing hole (11) of the fixed seat (1) correspondingly. The threaded stop ring (4) enables the rotating seat (6) to be fixed to the fixed seat (1). The threaded stop ring (4) is in threaded connection with the fixed seat (1). Four limiting steel balls (17) on the rotating seat (6) are matched with four limiting grooves formed in the fixed seat (1). The first spray nozzle (5), the second spray nozzle, the third spray nozzle and the fourth spray nozzle are installed inside four spray nozzle installing holes (16) formed in the rotating seat (6).

Description

technical field [0001] The invention relates to a device belonging to the technical field of digital processing, more precisely, the invention relates to a rotatable and switchable nozzle of a 3D printer. Background technique [0002] 3D printing is based on a digital model, by slicing the digital model, using melt extrusion technology, laser sintering technology or photo-curing sintering technology to print layer by layer to complete the production of objects. [0003] 3D printers are less efficient at actually printing objects and take too long to print. For the melt-extrusion 3D printer, the object is printed by spraying materials. When printing a solid object, it is necessary to fill the inside of the object with material. People cannot see the inside of the object, as long as the filled material can support the outside. up. Therefore, you can increase the printing speed by setting the filling ratio, so that the material filled inside the object is reduced and the prin...
