Multi Jet Fusion (MJF) is quickly becoming a popular choice for 3D printing prototypes and production parts. Ideal uses for MJF are enclosures, electronics housings, complex ducts, lattice structures, and functional assemblies. The technology is capable of 3D printing parts with high detail, as well as suitable for applications that require durability (e.g. snap fits). It is common for designers and engineers to choose this material for short production runs because the MJF process allows for nesting in the z direction.
Offering this technology further expands FATHOM’s all-ready comprehensive 3D printing and additive manufacturing services. To learn more about MJF, read a featured FAQ blog post by a FATHOM Applications Engineer.

How does it work? Multi Jet Fusion, or MJF, builds parts by laying down a thin layer of powder on a print bed over and over. The inkjet array in the print carriage sweeps over the print bed, jetting two agents downward—a fusing agent, printed where the powder will fuse together, and a detailing agent that is used to reduce fusing at the part boundary to achieve greater detail.
Nylon 12 is a commonly used thermoplastic that is strong enough for functional prototyping and production parts, small to medium in size—ideal for complex assemblies, housings, enclosures, and watertight applications. Achieve smooth surfaces and fine details with this durable material. It provides excellent chemical resistance to oils, greases, aliphatic hydrocarbons, and alkalies. Parts produced are a non-uniform light gray and can be dyed a darker color for a uniform appearance.
