The large setting angle of feeding screen surface could make the materials spread rapidly and go through the screen easily after entering the feeding screen, reduce screen surface wear, and increase the handling capacity per unit area; the diminishing setting angle of intermediate screen and discharge screen can lower relatively the speed of materials and improve the screening efficiency.

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.
