MJF 3D Printing


Create dimensionally stable, repeatable parts with Purple Porcupine’s Multi Jet Fusion (MJF) 3D printing services.

Multi Jet Fusion

Why MJF?

MJF technology provides repeatability and dimensional stability.

The method allows us to print functional, geometrically complex parts, with a layer thickness of 0.003 inches (or 0.08 mm).

MJF is ideal for designs with complex geometries, including parts with internal cavities.

This cost-effective method of 3D printing is perfect for quantities greater than 30 pieces.

PA 12 is strong thermoplastic with excellent chemical resistance and low moisture absorption. PA 12 is ideal for complex assemblies, enclosures, lattice structures, and connectors.

PA 12 GB, also known as PA 12 GF, is a dimensionally stable thermoplastic that is 40% filled with glass beads, allowing it to produce stiff, functional parts. PA 12 GB is ideal for functional parts, like jigs, fixtures, housings, and enclosures.


From batch production for testing and validation to end-use parts, MJF 3D printing applications are nearly endless. Some of the common design applications include: connectors, brackets, covers, thin-wall ductwork, non-cosmetic housings, grommets, wiring clips, and guides. MJF is ideal for designs with complex geometries, including parts with internal cavities.

The Process

Multi Jet Fusion is a powder-based technology that uses an inkjet array to selectively apply fusing agents across a layer of nylon powder. The nylon powder selection is fused by heat into a solid layer.

After a layer is created, powder is distributed on top of the bed again. The process repeats until the part is complete. To learn more, contact our team today!

At Purple Porcupine, you can depend on our 3D printing & rapid prototyping service to be exceptional, and our 3D printed models to hold tight tolerances with premium finishes. We use only the best of rapid prototyping technologies that will provide optimal solutions to change the way you design and create products.
