Description
Technical Field
The invention relates to a 3D printing droplet ejection measurement system and a method, belonging to the field of 3D printing (droplet ejection free forming technology) droplet ejection measurement.
Background
The uniformity, size and ejection of the ejected droplets directly determine the quality and manufacturing time of the printed object. At present, a spray head using vibration of a piezoelectric plate as a power source is widely applied due to a simple structure and easy realization, but the difficulty of spraying is greatly increased when the diameter of liquid drops reaches a micron level due to the viscosity, tension and other factors of liquid. For liquids with different viscosities, the driving voltage amplitude, the driving voltage frequency and the diameter of the nozzle of the pressure head can influence the uniformity, the spraying speed and the size of the liquid drops, and can cause bad conditions such as liquid bands, satellite liquid drops and the like to seriously influence the printing quality.
In general, most of domestic and foreign droplet ejection systems are not equipped with an ejected droplet measurement system, and few types of droplet ejection systems have a rough observation function, so that an acquired droplet image is blurred, and the size and ejection speed of a droplet cannot be accurately measured. Under the condition that the liquid drop parameters cannot be obtained, the qualification rate of the printed product is low, and the good printing effect can be obtained only by multiple debugging and multiple tests, so that the efficiency is low. The reason why the droplet size and the ejection speed cannot be accurately obtained at present is that, due to different spatial arrangements of laboratories, focusing and shooting cannot be completed without a mobile device capable of flexibly moving in space.
