MJF
production, not prototypes
Multi Jet Fusion. HP’s industrial polymer process. Inkjet arrays lay down fusing and detailing agents on a nylon powder bed, then infrared heat fuses the lot. Strong, isotropic, and produced at up to 10× the speed of SLS.

01 Why use it
the good bits
- Production-grade properties: isotropic strength in X, Y and Z; impact and chemical resistant.
- The fastest polymer 3D process: full builds in 10 to 15 hours, thousands of parts shipped per week.
- No supports required: complex internal geometry, interlocking assemblies, captive features.
- Lowest cost per part at 10–10,000 units: the bridge between prototyping and injection moulding.
- 500 micron minimum feature, consistent grey finish that dyes deep black.
- Closed-loop thermal control: repeatable batch to batch.
02 Ideal volumes
how many?
- 10–10,000 parts: functional end-use production at medium volume.
- Bridge production: ship real parts while injection moulding tools are being built.
- Jigs, fixtures and tooling: same-day spares with no CNC programming.
- Below 10, SLA or SLS often cheaper. Above 50,000, injection moulding wins.
