What is Multi Jet Fusion (MJF) 3D Printing?
Multi Jet Fusion (MJF) is a revolutionary 3D printing technology that redefines digital fabrication through a layer-by-layer printing process. Unlike traditional methods, MJF combines high-speed sintering with inkjet 3D printing to fuse thermoplastic powders into durable, precise parts—making it ideal for both rapid prototyping and industrial 3D printing applications. As a leading polymer 3D printing technique, MJF eliminates many design limitations, enabling the creation of parts with intricate details that were once impossible to manufacture.

With a rapid turnaround time (as fast as 24–48 hours for prototypes), we ensure your projects stay on schedule without compromising quality.
The MJF 3D Printing Process
The MJF workflow is a streamlined, digital-driven cycle that transforms CAD files into physical parts. Below is a step-by-step breakdown:
- Digital Design & CAD Modeling: Engineers create or refine 3D models using CAD software, optimizing for MJF’s capabilities (e.g., complex geometries).
- Slicing Software: The CAD model is sliced into thin layers (50–100 microns) and converted into machine-readable code.
- Build Preparation: Thermoplastic powder (e.g., Nylon 12) is loaded into the MJF printer, and the build chamber is preheated to optimal temperatures.
- Print Execution: The printer performs powder spreading (evenly distributing a thin layer of powder) and inkjet binding (depositing fusing agents).
- Infrared Heating: An infrared lamp applies heat to fuse the bound powder layers together—this is the core of layer fusion.
- Post-Processing: Parts are removed from the powder bed, cleaned, and finished (e.g., sanding, coating).
Quality Control: Parts undergo dimensional testing and material property checks to ensure compliance with standards.
MJF Compatible Materials
MJF excels with a range of thermoplastic powders and functional materials, each offering unique properties for specific applications.
| Material | Mechanical Strength | Thermal Resistance | Chemical Resistance | Typical Application |
| Nylon 12 (PA 12) | High | Up to 180°C | Excellent | Aerospace brackets, medical tools |
| High-Density Polyethylene (HDPE) | Medium | Up to 120°C | Good (resists oils/solvents) | Industrial containers |
| Polypropylene (PP) | Medium | Up to 150°C | Excellent | Consumer goods, automotive parts |
| Composite Materials (e.g., PA 12 + glass fiber) | Very High | Up to 200°C | Excellent | Heavy-duty tooling, structural parts |
| Elastomers | Low (flexible) | Up to 100°C | Good | Gaskets, seals, soft-touch components |
All our MJF compatible materials are tested for consistency, ensuring parts meet or exceed industry standards for performance.
MJF Surface Treatment Options
Post-processing is critical to enhancing the aesthetics and functionality of MJF parts. Our MJF surface finishing services include:
- Sanding: Smooths rough surfaces and removes excess powder (ideal for parts requiring a matte finish).
- Polishing: Creates a glossy, professional look for consumer-facing parts (e.g., electronics enclosures).
- Painting/Coating: Adds color, UV protection, or chemical resistance (e.g., anti-corrosion coatings for automotive parts).
- Vapor Blasting/Media Blasting: Uses compressed air and media (e.g., plastic beads) to achieve a uniform, textured surface.
- Chemical Etching: Refines fine details and improves adhesion for coatings.
These treatments not only boost aesthetic improvement but also enhance functional coatings that extend part lifespan.
MJF Tolerances & Precision
MJF precision is a key advantage, making it suitable for parts requiring tight dimensional control.
| Feature | Specification |
| Dimensional Accuracy | ±0.1 mm for parts up to 100 mm; ±0.1% for larger parts |
| Tolerance Levels | Typical: ±0.05 mm (for critical features) |
| Repeatability | <0.03 mm variation across 100+ identical parts |
| Dimensional Stability | Minimal warpage (<0.5%) even under thermal stress |
| Measurement Standards | Compliant with ISO 13485 (medical) and AS9100 (aerospace) |
Our quality inspection processes (e.g., 3D scanning, coordinate measuring machines) ensure every part meets your tight tolerances and maintains consistency batch after batch.
Key Advantages of MJF 3D Printing
MJF outperforms traditional manufacturing and other 3D printing technologies in multiple ways:
- High-Speed Production: Up to 5x faster than selective laser sintering (SLS) for large batches.
- Cost-Effective: Reduces material waste (95% of unused powder is recyclable) and eliminates tooling costs.
- Reduced Lead Time: Cuts production timelines from weeks to days (critical for time-sensitive projects).
- Enhanced Design Freedom: Prints complex structures (e.g., lattice patterns, internal channels) without assembly.
- Lightweight Parts: Creates strong, lightweight components that reduce product weight (e.g., 30% lighter aerospace parts).
Environmental Sustainability: Lower energy use (vs. injection molding) and minimal waste support green manufacturing goals.
