Process overview

MJF Capabilities

Each 3D printing process page follows the same review path: choose a process, upload part data, confirm material and finish needs, then lock the submitted quote snapshot before order confirmation.

Batch Production

Parts can be nested efficiently for low-volume production and repeat manufacturing runs.

Nylon Performance

PA12 and PA11 options support durable, functional parts with practical chemical resistance.

Fine Feature Resolution

Good edge definition and feature quality for clips, text, threads, and small interfaces.

Finish Options

Grey as-built parts can be dyed black or finished for more consistent presentation.

MJF Materials

PA12 Standard

Tough, chemical-resistant nylon for functional prototypes and end-use parts.

PA12 Natural

Lighter grey nylon suited to dyeing and appearance control.

PA11

Bio-based nylon with improved elongation and impact resistance.

PA12 Glass-Filled

Increased stiffness and dimensional stability for selected applications.

Common questions

Questions about HP Multi Jet Fusion (MJF)

How does MJF compare to SLS?

MJF is often faster and cost-effective for PA12 batches, while SLS has broader material options and different part-size constraints.

Are MJF parts suitable for end-use?

Yes. PA12 MJF parts are commonly used for functional housings, clips, covers, and small production runs after fit and load review.

Can MJF parts be dyed?

Yes. Black dyeing is common, and selected custom appearance requirements can be reviewed before quote submission.
