MJF 3D Printing Service

IPFL's HP MJF (Multi Jet Fusion) 3D Printing Service Produces Tough 3D Printed Prototypes and Production Parts

What is MJF 3D Printing?

IPFL’s MJF 3D Printing Service (Multi Jet Fusion) is an advanced 3D printing process that uses heat and a fusing agent to bond fine layers of powdered material, typically nylon (PA 12). A thermal print head selectively applies fusing agents, then heat is applied to create strong, detailed parts — layer by layer.

MJF 3D printing, from HP, produces high-quality, watertight parts with excellent mechanical strength, fine detail, and smooth surfaces. It’s ideal for functional prototypes, end-use components, and low-volume production.

This technology easily handles complex geometries and internal features, outperforming many other additive manufacturing methods. It’s commonly used with engineering-grade nylon materials, offering High strength and stiffness, Excellent chemical resistance (to oils, greases, hydrocarbons, alkalis), Low moisture absorption, Superior wear resistance

MJF is perfect for industrial 3D printing needs — fast, accurate, and ready for real-world use.

Minimum Feature Size: 0.8 mm
Tolerances: ± 0.3 % ± 0.3% (lower limit: ± 0.15 mm)
Materials: Rigid & Flexible

How does the MJF 3D printing process work?

MJF 3D printing combines inkjet printing and powder bed fusion to produce strong, accurate nylon parts. The process begins by spreading a thin layer of thermoplastic powder, usually nylon PA12, across the build platform.

An inkjet print head selectively applies a fusing agent where the part should solidify. A heat source then melts and fuses the powder together. This is repeated layer by layer until the final part is complete.

Layer thickness can be adjusted to meet your design’s strength, resolution, and surface finish requirements.

Thanks to its precision and repeatability, Multi Jet Fusion is ideal for Functional prototypes, End-use parts, Low-volume manufacturing, Medical device components and Engineering-grade applications.

With its fast build speed, fine detail, and consistent results, MJF 3D printing is a powerful solution for demanding industries.

MJF vs SLS

Speed and Efficiency -MJF surpasses SLS with multiple print heads, perfect for intricate projects on tight schedules.
Sustainable Printing - MJF and SLS recycle powder, but MJF's higher reuse ratio boosts sustainability and cost-efficiency over SLS.
Smoother Surface Finish - Choose MJF for a superior, smoother surface finish, surpassing SLS print quality.
Consistent Part Quality - MJF ensures consistent quality and precise dimensions, surpassing SLS variations.
Expansive Material Selection - MJF offers versatile materials, like low-moisture & robust PA 12 (nylon), surpassing SLS.
Cost-Effective - MJF materials are often more affordable than SLS, ensuring cost-effectiveness for specific applications.

Advantages of MJF printing

Multi Jet Fusion (MJF) offers a fast, scalable, and cost-effective solution for both prototyping and production parts.

Unlike other 3D printing methods, MJF prints entire layers at once, not point by point. This makes it significantly faster — ideal for tight deadlines, rapid prototyping, and high-volume production. With no tooling costs and short setup time, you can move straight from design to production.

Key Benefits of MJF Printing:

  • Fast Turnaround – Full layers are fused at once, speeding up print cycles
  • Cost-Effective – Low input cost, no tooling required, high material efficiency
  • Production-Grade Nylon – MJF uses PA12 and PA11, tough thermoplastics with strong mechanical properties
  • High Precision – Fine detail, excellent surface finish, and tight dimensional tolerances
  • Functional Prototypes & End-Use Parts – Durable, isotropic properties for working components
  • Complex Geometries – Supports internal channels, snap fits, and fine features without supports
  • Scalable – From one-off prototypes to low-volume or batch production

Engineered for Performance

Whether you’re validating a design, building a robust prototype, or scaling up to volume manufacturing, MJF delivers production-quality parts fast, without compromising on performance.
Our MJF 3D printing service delivers parts that are:

  • Strong and Durable
  • Chemically Resistant
  • Repeatable and Consistent
  • Ready for Testing or End-Use
