MJF - Multi Jet Fusion — 3D Printing Process

Fast, strong nylon printing for functional parts and end-use products.

HP Multi Jet Fusion applies fusing and detailing agents onto a nylon powder bed, delivering fast print speeds, consistent mechanical strength and excellent dimensional stability for end-use parts.

Engineering parameters

MJF - Multi Jet Fusion parameters
Layer Height	0.08 mm — Fast build speed with good surface quality.
Minimum Wall Thickness	1.0 mm — Recommended 1.2 mm for functional parts.
Minimum Feature Size	0.5 mm — Fine textures and engraved details supported.
Tolerance	+/-0.3 mm — For most standard geometry.
Support Structure	Not required — Powder bed self-supports the part.
Max Build Size	380 x 284 x 380 mm — Larger parts can be split and assembled.
Lead Time	From 48 h — Batch lead time depends on quantity and finish.

How to order custom 3D printing

Samples start from 1 piece so the print can be approved before a bulk run.
Bulk pricing tiers start at 10 pieces and step down again at higher quantities.
A proof is sent for approval before the batch is produced.
Upload STL, STEP, STP, OBJ, 3MF, GLB or GLTF. Up to 20 files per request, 100 MB per file.
Keep walls above 1.2 mm and never below 0.8 mm for a reliable, printable part.
Your files stay confidential and are used only to quote and print your order.
Printed in our own factory, so no tooling is required and MOQ stays low.
Shipped worldwide by express courier, air or sea freight with tracking.
