Embodiment 1

[0032] refer to figure 1 and figure 2 , a 3D printer, comprising a mounting bracket 10, a workbench 20 and a spray head 30, the spray head 30 and the workbench 20 are arranged on the mounting bracket 10 and the spray head 30 is located above the workbench 20, and the spray head 30 includes a nozzle 2, a delivery pipe 3 and an extrusion Mechanism 4, the delivery pipe 3 is connected to the nozzle 2, and the extrusion mechanism 4 is connected to the delivery pipe 3. During the working process of the extrusion mechanism 4, the molten material 6 in the delivery pipe 3 is sprayed on the workbench 20 through the nozzle 2 .

[0033] refer to figure 1 , the solid material enters the feeding pipe 3 corresponding to the nozzle 2 after being melted at high temperature, and the feeding pipe 3 corresponding to the extruding mechanism 4 (under the action of the extruding mechanism 4 undergoes elastic deformation. Corresponding to the extruding mechanism 4 During the process of elastic de...

Embodiment 2

[0054] In this embodiment, the 3D printer is the 3D printer in Embodiment 1.

[0055] The difference from Embodiment 1 is that in this embodiment, the 3D printer has a pressure compensation method.

[0056] A pressure compensation method for a 3D printer, comprising the steps of:

[0057] S01) The controller sets the pressure signals P1, P2 and P, P1

[0058] S02) The nozzle moves relative to the workbench until the force of the extrusion nozzle on the workbench is transmitted to the controller through the sensor. During the process of transmitting the force of the extrusion nozzle on the workbench to the controller through the sensor, the controller Signal, calculate and generate height values ​​at different positions of the workbench.

[0059] In this embodiment, "the nozzle moves relative to the worktable" has the following two ways of understanding: 1. First, the nozzle moves along its height direction until the molten material ejected from the outlet on the nozzle...

Abstract

The invention relates to a 3D printer and a pressure detection method and a pressure compensation method thereof, and solves the problem that the 3D printer is poor in printing quality. The 3D printer comprises a mounting support, a working table, a sprayer and a controller, wherein the sprayer and the working table are arranged on the mounting support; the sprayer is positioned above the working table and comprises a nozzle, a conveying tube and an extrusion mechanism; the conveying tube is connected with the nozzle; the extrusion mechanism is connected with the conveying tube; the sprayer further comprises a shell and a sensor; the shell is connected with the controller through a driving mechanism; the extrusion mechanism and the sensor are electrically connected with the controller; the shell has an upper limit position and a lower limit position; the nozzle is movably arranged on the shell and moves between the upper limit position and the lower limit position in a reciprocating manner; and the sensor is arranged on the shell to detect the height position of the nozzle on the mounting support.

Description

technical field [0001] The invention relates to a 3D printer, a pressure detection method of the 3D printer and a pressure compensation method thereof. Background technique [0002] The 3D printer includes a mounting bracket, a workbench and a feeding mechanism, the feeding mechanism includes a spray head, the spray head and the workbench are arranged on the mounting bracket, and the spray head is located above the workbench. [0003] The nozzle includes a nozzle, a feeding pipe and an extruding mechanism. The feeding pipe is connected to the nozzle, and the extruding mechanism is connected to the feeding pipe. During the working process of the extrusion mechanism, the material in the feeding pipe is sprayed onto the workbench through the nozzle to Realize the printing of 3D models. However, in the working process of the existing 3D printer, the nozzle may collide with the workbench with a certain probability, which will reduce the printing quality of the 3D printer. Cont...
