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.

These powder-bed fusion nylon parts also offer good fatigue resistance and dimensional stability, making them practical for long-term load-bearing structures and moving assemblies. For low volumes they deliver performance close to injection-molded parts without tooling costs. Compared with SLS, the process generally provides better isotropy and denser surface quality.
Complex Geometry in a Single Build
Because the surrounding powder supports the part, MJF needs no support structures. Internal channels, lattices, thin walls (recommended minimum 0.8–1.0 mm), freeform surfaces, and other geometries that are difficult or impossible to produce in one step with injection molding or CNC can be built as a single monolithic piece. This reduces or eliminates assembly steps.
The absence of tooling shortens prototyping to a few working days and keeps low-volume custom production far more economical than traditional mold development. Common applications include connector housings, fluid fittings, custom brackets, parts with internal cooling channels, and lightweight structural components.
Material Options
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.
post-processing
After printing we offer a complete set of finishing options so parts meet both functional and aesthetic requirements:
Dyeing / coloring - primarily deep black (standard for MJF), with uniform penetration and better abrasion resistance than surface painting
Surface treatments - bead blasting to remove residual powder and even the surface, polishing, and vapor smoothing for improved sealing and finish
Secondary operations - thread tapping or inserts, pad printing or silkscreen marking, airtightness treatment, and simple assembly
Handling dyeing, blasting, and finishing in-house reduces the need to coordinate multiple suppliers and shortens overall lead time.

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.
