Manufacturing Process
Phase A - Preparation
Weigh all the components accurately according to the formulation.
Pre-dry ABS pellets in a vacuum oven at 80°C for 2 hours.
Phase B - Mixing
Load ABS pellets into a high-shear mixer.
Gradually add graphene nanoplatelets while maintaining rapid agitation.
Introduce PVP and mix until the graphene is uniformly dispersed.
Add remaining components: MMA, Butadiene, Stearic Acid, and Antioxidant Package.
Phase C - Extrusion
Transfer the mixed composite to a twin-screw extruder set at 210°C.
Extrude into filament through a 1.75mm die.
Cool and spool the filament to prevent any moisture uptake.
Usage Instructions
Use this filament with an FDM/FFF 3D printer equipped with a hardened steel nozzle to prevent wear. Set the nozzle temperature to 230-250°C and bed temperature to 90-110°C for optimal adhesion.
