High-Speed MJF 3D Printing for End-Use Production
Multi Jet Fusion (MJF) represents a paradigm shift in additive manufacturing, moving from rapid prototyping to rapid manufacturing. Unlike laser-based systems (SLS), MJF utilizes an array of inkjet heads to apply fusing and detailing agents across a bed of nylon powder, which are then fused by infrared energy. This process is significantly faster and produces parts with higher density and finer detail.
At JUCHENG, we utilize industrial MJF technology to deliver functional nylon parts that rival injection molding in strength and surface quality. Our facility is optimized for batch production, allowing us to print hundreds of distinct geometries in a single run. Whether you need watertight fluid connectors, robust drone chassis, or custom automotive clips, our MJF service offers the speed and scalability required for low-to-mid volume manufacturing.

MJF 3D Printing
JUCHENG’s MJF Manufacturing Capacities
We unlock the full potential of Multi Jet Fusion technology through optimized workflows:
- Isotropic Strength: We fine-tune cooling profiles to ensure parts have uniform mechanical strength in the X, Y, and Z directions. This solves the "weak Z-axis" issue common in other 3D printing methods.
- High-Density Production: MJF parts are non-porous and watertight right out of the printer. We ensure density consistency for pressure-bearing applications.
- Standard & Advanced Finishing: Raw MJF parts are grey. We provide standard Black Dyeing (for a uniform look), Media Tumbling (for smoothness), and Vapor Smoothing (for a sealed, semi-gloss finish).
- Volume Scalability: Our nesting algorithms maximize the number of parts per build, driving down the unit cost for batches of 500+ units.

Why Choose Us
The JUCHENG MJF Advantage
- Production Mindset: We don't just print prototypes; we manage "bridge production." We offer dimensional reports and material certifications for batch orders.
- Finishing Excellence: Raw MJF grey can be uneven. Our automated Black Dyeing process ensures a deep, consistent cosmetic finish that looks professional.
- Fast Turnaround: MJF's high print speed allows us to ship large batches (e.g., 200 parts) in as little as 3 days.
- Cost Optimization: We help you redesign parts (hollowing, latticing) to reduce material volume and print time, lowering your per-part cost.
Advantages
Key Benefits of MJF Technology
- Speed: Prints fully packed build chambers faster than SLS, reducing lead times for volume orders.
- Detail Resolution: The "Detailing Agent" creates sharper edges and finer textures than laser sintering.
- Strength: Parts are dense and strong in all directions, suitable for functional end-use.
- No Supports: Like SLS, MJF requires no support structures, enabling unlimited geometric freedom.
