Way is off printing manual cleaning printer head, time-consuming and laborious in this way, influences printing effect.
There is a kind of 3D printer blocking prison mentioned using the such as application number 2018102300530 detected automatically at present
Prosecutor method obtains the image of 3D printhead heater charging end position in real time；According to the image detection of acquisition wherein feed entrance point
Stock diameter；Judge whether the stock diameter detected is more than preset diameters, determines 3D spray head stopping state.This scheme needs pair
3D printer is modified source program, and configuration detection program, there are poor compatibilities for the 3D printer source program based on different model
The drawbacks of, and detection process is easy to appear color difference, and the factors such as gray scale difference be easy to cause maloperation or erroneous judgement to influence 3D printing
It is normally carried out.
A kind of also such as application number 201611241098.5, solution based on the blocking of FDM technique printing head, passes through
When making each printed material, material component with shear thinning characteristic, so that 3D printing process compatible with basis material is added
In, when at equipment spray head due to the presence of its pyramidal structure particle and by shear force, the viscosity of printed material is reduced,
Mobility is increased, thus the phenomenon that efficiently solving printing head blocking.This scheme needs to configure corresponding printed material, is
Improvement to printed material, improves printed material required for 3D printing, but its narrow scope of application, defines
Printed material is not suitable for carrying out wide popularization.It is be easy to cause the restriction because of printed material, and some pairs of printed materials is caused there are lattice
The technical field of outer requirement can not be applicable in the program and spray head is avoided to block.
