Multi Jet Fusion 3D Printing Services
Get 1 to 1000+ custom production parts and prototypes using HP’s multi jet fusion (MJF) 3D printing technologies.
How MJF 3D Printing Works
Multi jet fusion (MJF) — using HP’s 3D printers — fuses nylon
powder layer-by-layer using infrared energy and fusing and
detailing agents to deliver strong, repeatable parts with fine
feature resolution and excellent surface uniformity.
This method creates isotropic mechanical property parts unique
to 3D printing, giving you powder-bed printing with higher
resolution, smoother surface finish, and superior production
throughput.
Common MJF Applications

Housings & Covers
Ducts & Manifolds
Snap-Fit Clips & Living Hinges

Production Parts
Mass Customization & High-Mix
At a Glance: When to Choose
MJF vs. Other Processes
A3D offers application-first guidance. If another process (such as CNC, SLA, SLS, FDM, urethane casting, or sheet metal) will outperform MFJ on cost, weight, or schedule, we’ll recommend it – so you work with one partner from prototype to production.
Comparison
MJF vs. SLS 3D Printing.
MJF vs. FFF/FDM 3D Printing.
MJF vs. SLA 3D Printing.
MJF vs. CNC Machining.
Reason
MJF typically offers smoother as-printed surfaces and faster turnarounds for production parts.
MJF offers better feature resolution and isotropy. FDM may win on ultra-large builds or
specific materials.
MJF offers functionality, durability, and productivity. SLA wins on ultra-smooth cosmetics and hard and soft tooling masters.
MJF accommodates complex geometries without tooling. CNC wins on metals and tight tolerances.

Material
- Nylon PA 12 – Gray or White: General-purpose strength, good dimensional stability, smooth surface. Great for enclosures, brackets, and fixtures.
- Nylon PA 12 – Full-Color: Cosmetic models and prototypes with labeled features, icons, or color-coded part states.
- Nylon PA 12 – Smooth: Same mechanical properties as PA 12, but with a smoother finish fresh off the printer. Better final finish when coupled with other finishing options.
- Nylon PA 12 – GB (glass bead): Stiffer parts and improved wear resistance. Great for jigs and housings.
- Nylon PA 11: Higher flexibility and impact resistance. Great for living hinges, clips, and snap-fits.
- TPU/TPA: Elastomeric or rubber-like materials. Great for parts like gaskets, grips, and energy absorption.
- Polypropylene (PP): Chemical resistance and flexibility. Great for things like fluid-handling components.
Max Part Size
- 380 x 284 x 380 mm (≈ 15.0 x 11.2 x 15.0 in)

Yes, we offer PA 12 Full-Color for visual models and TPU/TPA for elastomeric parts.
We offer standard bead blast, mechanical smoothing, vapor smoothing, black dye and premium dye, drill or
tap, inserts, bonding, and select coatings like Cerakote or paint for certain use cases.
Nope, there are no minimums. You can build 1 to 1,000+ parts and scale how and when you want.
Absolutely. Our guidance is application-first and process-agnostic. We’ll recommend MJF, CNC, or a hyrbrid
approach based on performance and risk, not convenience.
