Introduction Recent developments nowadays in electrical power generation and storage systems shows polymers are widely used as electrical conductors, ionic conductors, polymer electrolytes, static dissipative materials and etc [1].
A conductive polymer composite has a polymer as a matrix and electric conductive materials as fillers.

Then the rapid prototyping machine will control nozzles according to the NC program, extrude the fusion materials directly, cool and freeze them in certain temperature, transfer heat from fusion materials to noumenon, and combine them together.
The raw materials that have been used are the filament ABS plastic.
Extrude unit crams these materials into nozzles, and melts them by a process of gradually heating until molten state.

Introduction Screening machine is the device that classifies granular materials according to particle size, which forced material relative motion and let the granular material through the screen.
In order to improve the efficiency of screening, people carry out long-term research of vibrator structure, vibration frequency and vibration mode, the screen structure and materials and supporting mode.
Thus, effectively solve the problem of sticky wet material.
