Description
Technical Field
The invention relates to a surface treatment method of a 3D printing model, in particular to a method for cleaning the 3D printing model through centrifugal force.
Background
The clearance mode of photocuring 3D printing model commonly used among the prior art is usually for washing 3D printing model surface through ethanol, use ultrasonic oscillation, reuse air gun weathers 3D printing model, this kind of cleaning method is adopting the abluent in-process of ethanol, the ethanol of using reacts with resin easily, form the waste liquid, and if wash the ethanol change that 3D printing model used untimely, make a large amount of resin particles attached to 3D printing model on the surface easily, thereby lead to the stability of the model precision of printing out and quality relatively poor.
Disclosure of Invention
In order to solve the problems, the invention provides a method for cleaning a 3D printing model through centrifugal force, which is used for cleaning floating liquid remained on the surface of the 3D printing model after printing is completed through the centrifugal force generated by the 3D printing model in the process of high-speed rotation.
In order to achieve the above purpose, the method for cleaning a 3D printing model by centrifugal force according to the present invention is divided into the following steps:
a. applying a torsion to the printed 3D printing model;
b. the 3D printing model is rotated in a fixed axis mode through the applied torque force;
c. cleaning residual liquid on the surface of the 3D printing model through centrifugal force generated in the rotating process of the 3D printing model;
d. and carrying out subsequent processing on the cleaned 3D printing model. According to the method, residual liquid on the surface of the 3D printing model is thrown out through the high-speed rotation motion of the 3D printing model and the centrifugal force generated in the rotation process of the 3D printing model, so that the efficient surface cleaning efficiency of the 3D printing model is guaranteed, and a novel 3D printing model surface cleaning mode without ethanol cleaning is adopted.
Further, the centrifugal force generated by the rotation of the 3D printing model in the step c is specifically: in the step b, the fixed axis rotation of the 3D printing model specifically comprises the following steps: the rotating shaft is inserted into the 3D printing model, the rotating shaft rotates to drive the 3D printing model to rotate around the rotating axis of the 3D printing model, and the residual liquid on the surface of the 3D printing model is thrown out by the centrifugal force generated in the rotating process of the 3D printing model. Compared with a 3D printing model cleaned by ethanol, the 3D printing model cleaned by the method is smoother when observed macroscopically, residual liquid on the surface of the 3D printing model is thrown out by centrifugal force generated in the process that the 3D printing model moves circularly around the rotation axis of the 3D printing model, and meanwhile, resin particles on the surface of the D printing model can be attached to the surface of the model to fill the concave part of the surface of the model when the 3D printing model is at a certain rotating speed and can be utilized because the microstructure of the surface of the 3D printing model made of resin is irregular and is an unsmooth surface when observed macroscopically.
The further scheme is that the fixed-axis rotation of the 3D printing model in the step b specifically comprises the following steps: through the cleaning equipment of suit on the axis of rotation, with a plurality of 3D print model fixed mounting in the outside of axis of rotation to through the centrifugal force that 3D print the model and do the in-process production of centre of a circle motion around the axis of rotation, throw away the remaining liquid on 3D print model surface. According to the method, the cleaning equipment rotates at a high speed to drive the multiple groups of 3D printing models to move around the rotating shaft in the middle of the cleaning equipment to make a circle center, so that the effect of simultaneously cleaning residual liquid on the surfaces of the multiple groups of 3D printing models is achieved, the waste liquid is avoided while the cleaning efficiency of the residual liquid on the surfaces of the 3D printing models is improved, and thrown resin can be recycled.
A further proposal is that a stabilizing measure for preventing the eccentricity problem in the fixed-axis rotation process of the 3D printing model is set in the step c;
the adopted stabilizing measures are specifically as follows: the electromagnetic coil is fixedly arranged on the magnetic material on the surface of the cleaning equipment and on the periphery of the magnetic material, a magnetic field is formed after the electromagnetic coil is electrified, the electromagnetic force borne by the magnetic material in the magnetic field can be divided into a repulsion component and a suction component, and the repulsion component borne by the magnetic material in the magnetic field is larger than the suction component, so that the magnetic material is influenced by the repulsion component in the magnetic field, and the eccentricity problem in the process of rotating the fixed shaft of the 3D printing model is prevented. According to the method, through the magnetic field formed by the magnetic material and the electromagnetic coil, when the 3D printing model moves around the rotating shaft of the cleaning equipment in the circle center mode, the magnetic material pushes the cleaning equipment towards the rotating shaft direction under the influence of the repulsive force component in the magnetic field, and therefore the rotating stability of the cleaning equipment is guaranteed.
Further, the subsequent treatment in step d specifically comprises: and carrying out final curing treatment on the 3D printing model. Compared with a method for cleaning the surface of the 3D printing model by adopting ethanol, the method reduces the working steps of intermediate ultrasonic oscillation and drying the 3D printing model by adopting an air gun, thereby further improving the surface cleaning efficiency of the 3D printing model.
According to the method for cleaning the 3D printing model through the centrifugal force, the 3D printing model is driven to do circular motion around the rotating shaft through the arrangement of the rotating shaft, residual liquid on the surface of the 3D printing model is thrown out through the centrifugal force generated in the rotating process of the 3D printing model, meanwhile, due to the microstructure of the surface of the 3D printing model made of the resin material, irregular fluctuation is achieved, when the 3D printing model reaches a certain rotating speed, the residual liquid on the surface of the 3D printing model is thrown out, meanwhile, resin particles remained on the 3D printing model can be used, pits on the surface of the 3D printing model are filled, and the size precision and the surface smoothness of the 3D printing model are improved.
