Three-dimensional printing mechanism and repairing method for component to be repaired

Abstract

The invention relates to a three-dimensional printing mechanism and a repairing method for a component to be repaired. The three-dimensional printing mechanism comprises a three-dimensional moving assembly, a printing assembly used for printing a target object, a distance measuring assembly and a control processing unit. The printing assembly is installed on the three-dimensional moving assembly. The three-dimensional moving assembly is used for driving the printing assembly to do three-dimensional movement. The distance measuring assembly is fixedly installed on the printing assembly, does three-dimensional movement together with the printing assembly and is used for measuring the distance between the printing assembly and a printing position of the printing assembly. The control processing unit is connected with the distance measuring assembly, the three-dimensional moving assembly and the printing assembly. According to the three-dimensional printing mechanism in the embodiment, due to the fact that the distance measuring assembly is fixedly installed on the printing assembly, dynamic printing in the vertical direction is achieved, and the three-dimensional printing mechanism can be applied to the industries like medical treatment and is remarkable in practicability.

Description

technical field [0001] This application relates to but is not limited to the technical field of 3D printing equipment, especially a 3D printing mechanism and a repair method for parts to be repaired. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. Based on the digital model file, the 3D printer constructs the target object on the printing reference plane of the base by contacting the nozzle with the target object layer by layer (that is, printing the target object ). Using this technology can realize fast, efficient and accurate display of digital models, and its manufacturing cycle is short, and there is no waste of materials. [0003] However, relevant 3D printers can only print statically, that is, for building models, they must be printed on the reference plane of the base, and the reference plane of the base cannot move up and down (taking upward printing as an example, during the printing process If the base moves upwar...

Problems solved by technology

[0003] However, relevant 3D printers can only print statically, that is, for building models, they must be printed on the reference plane of the base, and the reference plane of the base cannot move up and down (taking upward printing as an example, during the printing process If the base moves upward, the model will stand against the nozzle; if the base moves downward, the nozzle will be separated from the model; neither can complete the model and continue to spray paint materials); for parts repair, the position to be repaired must also be placed on the base The reference plane and the position to be filled cannot be moved up and down (the principle is the same as above, so I won’t repeat it); that is to say, the relevant 3D printer cannot perform dynamic 3D printing, and its application range is narrow and its practicability is poor.
