Multi Jet Fusion (MJF) 3D Printing in Los Angeles
Multi Jet Fusion is HP’s industrial nylon process: dense, consistent, production-grade parts with no support structures. When a project moves from prototype to a real production run — fifty enclosures, two hundred brackets — MJF is usually the technology that gets it there, printed and finished at our Glendale studio.
How MJF Works
MJF builds parts in a bed of nylon powder. An inkjet array deposits a fusing agent onto each cross-section, a detailing agent sharpens the edges, and infrared energy fuses the treated powder into solid material — layer after layer. Because the surrounding powder supports the build, no support structures are needed, and parts come out with uniform density and consistent mechanical properties in every direction.
What MJF Is Best For
- Production runs — tens to hundreds of identical nylon parts with repeatable quality
- Functional prototypes that must behave like the final product
- Complex geometries — internal channels, thin walls, and snap fits without supports
- End-use parts — housings, brackets, clips, drone and robotics components
Like SLS, MJF pricing is driven by how much of the build chamber your parts occupy — so nesting many parts in one run drops the per-part cost quickly. Parts commonly start around $40; see the 3D printing cost guide.
MJF vs Other Technologies
Versus SLS: both print support-free nylon; MJF parts are typically denser and more uniform, with faster throughput on batches. Versus FDM: MJF is stronger and more isotropic, at a higher price. For smooth visual surfaces choose SLA; for metal, DMLS.

MJF 3D Printing FAQs
What material does MJF use?
Primarily PA12 nylon — tough, chemically resistant, and suitable for end use. Parts print gray and are commonly dyed black for a uniform finish.
Is MJF good for production quantities?
Yes — that’s its sweet spot. Dense chamber nesting and fast cycle times make MJF the most economical way to 3D print tens to hundreds of nylon parts.
MJF or SLS — which should I pick?
MJF for production consistency and batch economics; SLS as an excellent all-rounder. Send your file and quantity and we’ll quote the better option — usually the same day.
How accurate is MJF?
Typical tolerance is around ±0.3% (with a lower bound of a few tenths of a millimeter), which suits most functional applications. Tell us your critical dimensions and we’ll advise.
