Mechanical Property Advantages
Unlike FDM or SLA, HP Multi Jet Fusion nylon parts show only minor differences in mechanical properties across the X, Y, and Z axes, delivering near-isotropic performance. This reduces the risk of interlayer failure under complex loads and makes the parts suitable for end-use functional components.

The values above are reference properties for PA12 MJF material, not guaranteed specifications for every finished component. Actual part performance depends on material grade, build orientation, geometry, processing conditions, and post-processing. For applications involving sustained loads, elevated temperatures, or repeated mechanical stress, material selection should be evaluated against the component's actual operating conditions.
PA12 MJF parts are suitable for functional prototypes and selected end-use applications where strength, dimensional consistency, and complex geometry are important. Their mechanical properties are generally more consistent across build directions than conventional FDM parts. For components exposed to repeated loading, elevated temperatures, or demanding operating conditions, the design should be evaluated using application-specific testing rather than material data alone.
Complex Geometry in a Single Build
MJF allows complex plastic components to be produced without conventional support structures. This makes it suitable for parts with internal passages, lattice structures, curved surfaces, snap-fit features, and integrated mounting details.
For assemblies that would otherwise require several separately manufactured pieces, MJF can help consolidate selected features into a single component. This may reduce fasteners, assembly operations, and potential alignment issues.
Wall thickness, internal channel dimensions, clearances, and powder removal openings should be reviewed during design evaluation. Our engineering team can check these details before production to identify potential manufacturing limitations.
MJF Materials for Different Applications
We run a range of engineering-grade materials on HP Multi Jet Fusion systems:
|
Material |
Key Characteristics |
Typical Applications |
|
PA12 (Nylon 12) |
Balanced overall performance with strong chemical resistance |
Everyday structural parts, enclosures, and functional prototypes where cost and reliability matter most |
|
PA11 |
Greater flexibility and longer fatigue life; bio-based origin |
Snap-fits, living hinges, and components that experience repeated flexing or impact |
|
TPU |
High elasticity, abrasion resistance, and vibration damping |
Seals, gaskets, grips, and energy-absorbing buffers |
|
Glass-filled Nylon (PA12 GB, etc.) |
Elevated stiffness, modulus, and heat resistance |
High-load brackets, fixtures, and structural elements that must maintain shape under sustained stress |
Selection is driven by expected loads, temperature range, and chemical exposure. Glass-filled grades are preferred when higher rigidity is the priority.
MJF Surface Finishing and Secondary Operations
MJF components can be supplied with different finishing and secondary operations depending on their functional and appearance requirements.
Bead Blasting
Removes residual powder and helps create a more uniform matte surface. It is suitable for general functional components and parts requiring a consistent appearance.
Dyeing
Black dyeing is commonly used for PA12 MJF parts. It provides a more uniform color than untreated powder surfaces and is suitable for housings, brackets, and visible components.
Polishing and Surface Smoothing
These processes can improve surface texture where the application requires a smoother finish. Their suitability depends on part geometry, wall thickness, and dimensional requirements.
Threading and Metal Inserts
Threaded holes, heat-set inserts, and other metal fastening features can be added through secondary operations where the design allows.
Printing and Assembly
Pad printing, silkscreen marking, and simple assembly can be arranged for components requiring identification or integration with other parts.
If a component has critical mating surfaces or tight dimensional requirements, these areas should be identified in the drawings before production so that suitable finishing or machining operations can be planned.

FAQ
Q: How does Multi Jet Fusion differ from SLS?
A: Both are powder-bed fusion processes that need no supports. MJF deposits fusing agents with inkjet heads and then applies infrared energy across the entire layer, which usually produces faster builds, better isotropy, and denser surfaces. SLS sinters powder point-by-point with a laser and offers a wider material selection plus advantages for certain oversized parts. When the priority is high strength, fine features, and shorter turnaround, Multi Jet Fusion is generally the stronger choice.
Q: What temperatures can these nylon parts handle in service?
A: PA12 reaches a heat-deflection temperature of about 175 °C at 0.45 MPa and 95 °C at 1.82 MPa. Continuous operating temperatures should stay lower and be verified against the specific load and environment. Glass-filled grades raise the heat-resistance ceiling further.
Q: What dimensional accuracy should I design for?
A: Typical tolerances are ±0.3 % (approximately ±0.2–0.3 mm on smaller features), depending on overall size, geometry, and build orientation. Critical mating surfaces can be brought into tighter tolerance with secondary machining when needed.
Q: How long does a typical order take?
A: Most rapid-prototype jobs finish within a few working days once the files are approved, depending on complexity and any requested post-processing. Production-volume lead times are confirmed case by case according to quantity and current schedule; expedited slots are available for urgent projects.
Q: Can metal inserts or threaded fasteners be added after printing?
A: Yes. We routinely install heat-set or ultrasonic inserts, machine threads, or press-fit metal components as secondary operations. These steps are planned during the quoting stage so the final assembly meets the required strength and alignment.
