Manufacturing Process

Phase A - Preparation

  1. Weigh all the components accurately according to the formulation.
  2. Pre-dry ABS pellets in a vacuum oven at 80°C for 2 hours.

Phase B - Mixing

  1. Load ABS pellets into a high-shear mixer.
  2. Gradually add graphene nanoplatelets while maintaining rapid agitation.
  3. Introduce PVP and mix until the graphene is uniformly dispersed.
  4. Add remaining components: MMA, Butadiene, Stearic Acid, and Antioxidant Package.

Phase C - Extrusion

  1. Transfer the mixed composite to a twin-screw extruder set at 210°C.
  2. Extrude into filament through a 1.75mm die.
  3. 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.
