What is HP Multi Jet Fusion?
HP Multi Jet Fusion (MJF) is a powder bed fusion technology that produces highly accurate, dense, and durable nylon parts at production speeds. Unlike traditional laser sintering that traces each layer with a single beam, MJF uses inkjet arrays to deposit fusing and detailing agents across the entire build area in a single pass.
This approach enables MJF to print multiple parts simultaneously at speeds up to 10 times faster than selective laser sintering (SLS), while delivering excellent surface quality and consistent mechanical properties.
MJF is ideal for functional prototyping, bridge production, and low-to-medium volume manufacturing where the cost of injection mold tooling isn't justified. Parts can be printed, finished, and shipped in as fast as one business day.
MJF Materials
HP-certified materials optimized for consistent properties and high powder reusability.
Nylon 12 (PA12)
High reusability nylon with balanced mechanical properties
General purpose, functional prototypes, production parts
Nylon 11 (PA11)
Bio-based nylon with higher ductility and impact resistance
Impact-resistant parts, living hinges, snap-fits
Nylon 12 Glass-Filled
40% glass bead reinforcement for increased stiffness
Structural parts, high-stiffness applications
Polypropylene (PP)
Chemical resistant with excellent fatigue properties
Chemical containers, automotive, living hinges
TPU (Flexible)
Elastomeric material for flexible and rubber-like parts
Gaskets, seals, grips, flexible components
Vapor Smoothing Available
Transform MJF parts with an exceptional surface finish through automated vapor smoothing. This batch-based process creates a uniform, sealed surface with a semi-gloss appearance that rivals injection molded parts.
Surface Benefits
- • Smooth, sealed surface finish
- • Semi-gloss appearance
- • Improved aesthetics for end-use parts
Performance Benefits
- • Increased tensile strength
- • Improved elongation to break
- • Enhanced fatigue resistance
Applications for HP MJF
From rapid prototyping to direct digital manufacturing at scale.
Concept Models
Create detailed, durable physical models for design reviews and stakeholder presentations with excellent surface quality.
Functional Prototypes
Build fully-functional prototypes with snap-fits, living hinges, and moving assemblies for real-world testing.
Production Parts
Manufacture end-use parts at scale with consistent quality and mechanical properties approaching injection molding.
Advantages of MJF Technology
Why engineers choose Multi Jet Fusion for functional parts and production.
Watertight Parts
Optimized build parameters produce fully dense parts that are inherently watertight without post-processing.
10X Faster Than SLS
Full-bed jetting technology prints entire layers at once, enabling production speeds far exceeding traditional laser sintering.
Balanced Properties
More isotropic mechanical properties across X, Y, and Z axes compared to other powder bed fusion processes.
Fine Feature Detail
80-micron layer resolution enables sharp edges, crisp text, and intricate geometric details.
Production Economics
Low per-part costs make MJF ideal for bridge production runs and low-to-medium volume manufacturing.
No Support Structures
Unfused powder supports parts during the build, enabling complex geometries without support removal.
