HP Multi Jet Fusion (MJF) 3D Printing Materials and Properties

With HP's introduction of Multi Jet Fusion technology, many things have changed in the 3D printing industry: the production capacity often 10 times higher than the old SLS technology, an uptime close to 100%, a very affordable production cost, but above all the production of excellent functional pieces, are greatly expanding the sectors where 3D printing has become convenient both from a technical and an economic point of view.

Let's see together what are the most used and effective materials of this technology.

The Four Main MJF 3D printing materials

1. Nylon PA12

With this material you can get robust thermoplastic high density parts with balanced property profiles and strong structures and provides good chemical resistance to oils, greases, aliphatic hydrocarbons, and alkalies.

Ideal for complex assemblies, housings, enclosures, and watertight applications. The versatility of this economical and light material makes it capable of competing in cost and quality with injection molding.

Summary: thanks to its properties, nylon PA12 make up about 80% of all MJF 3D printing production

Nylon PA12 final parts and functional prototypes (see the gallery) with fine detail and dimensional accuracy and, moreover, easy to finish with a good acrylic paint. Quote instantly your PA12 part


2. Nylon PA12 glass beads 40%

Stunning detail, the best in MJF 3D printing, and moreover stiff, dimensionally stable, top quality parts.

It greatly reduces the warping problems of pieces with large planar surfaces (see the gallery and learn more about PA12 GB 40%)

3. Nylon PA11

It provides an enhanced elongation-at-break (what are the main differences between PA12 and PA11?) and therefore impact resistance and ductility perfect for automotive interiors, prostheses, insoles, sports goods, snap fits, living hinges, and more. Learn more about nylon PA11

4. Polypropylene PP

Top chemical resistance, weldability and very low moisture absorption for prototypes and functional parts.

Ideal for a wide range of automotive, industrial, consumer goods, medical applications. What are the advantages of polypropylene?

There is no doubt that HP Multi Jet Fusion technology has revolutionized the 3D printing sector with its ability to produce not only perfectly functional prototypes but also runs in a few days and at competitive costs (and with much simpler design) compared with the injection molding.
