MJF 3D Printing Service
Our MJF (Multi Jet Fusion) production line delivers high-precision, end-use polymer parts using advanced HP additive-manufacturing technology. It’s designed for customers who need accurate, repeatable, and production-ready components straight off the printer.
At RYSE 3D, we run HP PA11 and PA12 materials to suit a wide range of functional applications:
- PA 11 (Bio-based Nylon 11) – High ductility, excellent impact resistance, and superior fatigue performance. Ideal for automotive interiors, snap-fit parts, protective housings, and flexible clips.
- PA 12 (Nylon 12) – Outstanding dimensional stability, fine surface finish, and durability under load. Perfect for enclosures, manifolds, tooling, and low-volume production parts.
Our in-house finishing options include bead blasting, dyeing, vapour fusing, machining, and inspection, ensuring every component meets production standards.

💬 MJF 3D Printing FAQs
What is MJF 3D printing and how does it work?
MJF (Multi Jet Fusion) is an advanced powder-based 3D printing process developed by HP. It uses precision inkjet arrays and infrared fusing energy to build parts layer by layer, creating dense, isotropic components with consistent mechanical properties in all directions. It’s ideal for functional prototypes and end-use production parts.
What makes MJF different from other 3D printing technologies?
MJF (Multi Jet Fusion) delivers exceptional accuracy, detail, and consistency, making it ideal for production-grade polymer parts. It uses a unique powder-bed fusion process to create dense, isotropic components with smooth surface finishes and fine feature resolution.
What materials can RYSE 3D print with MJF?
We offer PA11 and PA12 as standard — two high-performance nylons used across automotive, aerospace, and consumer industries.
- PA11: flexible, sustainable, and impact-resistant.
- PA12: strong, rigid, and highly dimensionally stable.
Both are perfect for functional, production-grade applications.
How accurate are MJF 3D printed parts?
MJF delivers exceptional dimensional accuracy, typically within ±0.2 mm, and an extremely consistent surface finish. The process produces parts that are ready for use straight off the build, with minimal post-processing required for most applications.
How quickly can MJF parts be produced and delivered?
At RYSE 3D, we can produce and ship MJF parts in as little as 1–3 days. Our in-house production workflow is optimised for rapid turnaround while maintaining repeatable, production-grade quality at any scale.
