Introduction
Industrial 3D printing transforms production. MJF and FDM technologies deliver precision, repeatability, and cost control for manufacturing. This guide outlines capabilities, compares performance, and defines integration steps.
Technology Overview
Multi Jet Fusion (MJF)
• Process: Powder bed fusion with fusing and detailing agents
• Materials: PA12, PA11, TPU, glass-filled nylons
• Advantages: High resolution (80–100 µm), isotropic mechanical properties, uniform surface finish
Fused Deposition Modeling (FDM)
• Process: Extrusion of thermoplastic filament
• Materials: ABS, PC, Nylon, ULTEM, carbon-fiber composites
• Advantages: Large build volume, high strength, low material waste, rapid prototyping
Performance Comparison
Parameter MJF FDM
Resolution 80–100 µm 200–300 µm
Mechanical Strength Isotropic Anisotropic (Z-axis weaker)
Build Speed Up to 40 mm/hr layerwise 15–25 mm/sec extrusion
Cost per Part Moderate Low for large parts
Post-Processing Minimal (powder removal) Support removal and surface finishing
Material Selection
• Nylon 12: High impact, chemical resistance (MJF)
• TPU: Elastic applications (MJF)
• ULTEM 9085: High heat, flame retardant (FDM)
• Carbon-fiber Nylon: High stiffness, lightweight (FDM)
Use Cases
• Functional Prototypes: Validate form, fit, function in days
• End-Use Parts: Low-volume production of functional assemblies
• Tooling & Fixtures: Custom jigs, guides, molds on demand
• Complex Geometries: Internal channels, lattice structures for weight reduction
Implementation Strategy
1. Design for Additive Manufacturing (DfAM): Optimize wall thickness, support minimization, lattice integration.
2. Material Testing: Validate tensile, fatigue, thermal properties per application.
3. Production Workflow: Automate build preparation, nesting, scheduling with build management software.
4. Quality Control: Implement in-line metrology, CT scanning, mechanical testing.
5. Scale-Up: Deploy modular printer farms, integrate with ERP/MES for real-time monitoring.
Conclusion
MJF and FDM offer complementary strengths. MJF delivers fine detail and isotropic properties. FDM scales large parts with high strength-to-weight ratios. Implement both to achieve low lead times, cost-effective low-volume runs, and agile production.
