Design advice
1/ Hollow Thick SectionsMJF needs no support structures, but solid areas thicker than 20 mm hold heat and can sink or warp. Core out heavy sections, keep walls uniform and add powder escape holes around 5 mm wide.
2/ Plan Clearances for Moving PartsLeave at least 0.5 mm between mating surfaces, and 0.7 mm or more for print-in-place hinges and assemblies, so neighboring features do not fuse together during the build.

MJF 3D Printing Materials

Our MJF materials are HP-certified engineering thermoplastics chosen for real service conditions. PA 12 offers balanced strength, PA 11 adds ductility and impact resistance, glass bead PA 12 adds stiffness, and TPU covers flexible, elastomeric parts.
HP PA 12 Nylon
The workhorse of Multi Jet Fusion. PA 12 produces dense, low-porosity parts with strong resistance to oils, greases and many chemicals. It is the default choice for housings, brackets, clips and functional assemblies.

3D Printing/01
Move from CAD to physical part in days. Validate form, fit and function with MJF, SLA, DLP and other additive processes, then iterate quickly before committing to tooling.
3D Printing Solution
Vacuum Casting/02
Need 20 to 50 production-quality parts? Vacuum casting from silicone molds gives near-molded surfaces and a wide range of urethane properties for pilot runs and market trials.
Vacuum Casting Solution
Injection Molding/03
When volumes reach the thousands, injection molding delivers the lowest unit cost and tight repeatability. We help you move from printed parts to production tooling without redesign surprises.

What's MJF 3D Printing ?

Multi Jet Fusion (MJF) is an HP powder bed fusion process. A thin layer of nylon powder is spread across the build area, and an inkjet array deposits fusing and detailing agents. Infrared energy then fuses each layer. Unfused powder supports the part, so complex geometry prints without support structures.

✓Material traceability
✓Batch consistency for production runs
✓In-process quality control
✓Dimensional inspection before shipment
✓Tolerances up to ±0.1 mm
✓Final inspection before delivery

Pros and Cons of MJF 3D Printing

Pros of MJF 3D Printing

Nearly Isotropic Properties

Nearly isotropic mechanical properties across the X, Y and Z axes.

No Support Structures

No support structures, so internal channels, interlocking parts and dense nesting are possible.

Economical Batch Production

Low cost per part for batches from 10 to 1,000+ units.

MJF 3D Printing Process

Cons of MJF 3D Printing

Grainy Surface Finish

The natural finish is grey with a slightly grainy texture, so cosmetic colors need dyeing or painting.

Not for Thin/Clear Parts

It is not suitable for transparent parts or walls thinner than 0.5 mm.

Warpage Risk on Large Flats

Large flat or very thick sections can warp without design adjustment.

Frequently Asked Questions
What is the difference between MJF and SLS?

Both fuse nylon powder without supports. MJF fuses whole layers using agents and infrared energy, while SLS uses a laser. As a result, MJF usually builds faster, gives finer detail and more consistent properties, and costs less at batch volumes.
