Abstract

The present invention relates to the technical field of printing equipment, in particular to a 3D printer, comprising an underframe, a power device and a printing device are provided on the top of the underframe, the printing device includes a booster, and a bottom of the booster is provided with A heater, the bottom of the heater is provided with a spray head, the top of the booster is connected with a feed port, the inside of the feed port is slidably connected with a material pipe, and the outer surface of the spray head is evenly arrayed with a plurality of A coolant tank, a fan-shaped fan is arranged between the adjacent coolant tanks. The device cooperates with fan fan, coolant tank, ring box, solenoid valve and heat-resistant elastic end to jointly solve the problems of high temperature, fan vibration, fixed-point cooling and increased printing wall thickness in the device. The material is cooled quickly and efficiently at a fixed point, and the opening shape and size of the heat-resistant elastic end can be changed according to the change of the wall thickness to adapt to the printing thickness, and the rapid cooling position and efficiency can be changed according to the printing thickness adaptation.

Description

technical field

[0001] The invention relates to the technical field of printing equipment, in particular to a 3D printer. Background technique

[0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even Print the shape of any desired item in the spaceship for the astronauts. But what 3D prints out is the model of the object, not the function of the object.

[0003] Existing 3D printers mostly use fans to cool the printing process. This cooling method is slow in efficiency. At the same time, according to the change of the printing direction of the nozzle, the fan cannot change the cooling direction accordingly, so the vibration of the fan and the direction of its wind force will affect the printing process. process affects.

[0004] At the same time, in the current 3D printing process, it is impossible to quickly and efficiently cool the molten printing material ...
