The Lab 3D printer filament extrusion line is composed of single screw extruder, die head, cooling water tank, traction system, winding system. It is applied to the extrusion molding of filaments. It is an ideal tool for research institute cause of it’s miniaturization, intelligence and high precision.

Function & Features：

1. Adopting international brand variable speed control motor for the extruder to make the plasticization stable and constant.
2. Using brand melt pressure and temperature sensor to ensure high accurate data.
3. Computer-based measurement and control system and user friendly operation interface, easy to control.
4. Formula Storage function.
5. Emergency stops and safety protection devices to protect the safety of the operator.
