ABOUT LFAM
Large-Format Additive Manufacturing with Composite & Plastic Pellets
1. What Is LFAM?
Large-Format Additive Manufacturing (LFAM) is the process of 3D printing very big parts—often meters in size—using pelletized thermoplastics or composite materials. Unlike traditional filament- or powder-based 3D printing, LFAM systems feed granules through a high-throughput extruder, enabling faster build speeds and lower material costs.
Why Pellet-Based 3D Printing?
Cost Efficiency:
Pellets cost up to 70% less than equivalent filament.
High Throughput:
Continuous feeding allows sustained deposition rates ≥10 kg/h.
Material Variety:
Wide range of engineering plastics and composites (PETG, ABS, PA, PP, PC, etc.).
Easy Recycling:
Regrind scrap parts directly into future builds.

How Does It Work?
1. Pellet Hopper: Load your selected polymer or composite pellet into the hopper.
2. High-Torque Extruder: A geared motor and screw convert pellets to molten filament.
3. Large-Format Gantry or Robotic Arm: Deposits molten material layer by layer to build big parts.
4. Optional Reinforcement: Integrate continuous fibers (carbon, glass) for extra stiffness in critical areas.
LFAM excels wherever you need large, strong, lightweight parts:
• Aerospace fairings & tooling
• Automotive prototypes & jigs
• Marine hulls & deck components
• Architectural models & formwork
• Industrial tooling & end-use parts

TOOLPATH GENERATION
After the CAD has been checked on printability, including wall thickness and overhangs, the toolpath plan can be generated based on parameters and printing strategy and sent to the WAAM system for printing.
