Industrial nylon parts with isotropic strength and fast throughput.
Multi Jet Fusion (MJF) applies fusing and detailing agents across a powder bed, then uses infrared energy to fuse each layer. The result is durable PA12 or TPU parts with fine feature definition and mechanical properties suited to serial production.
Multi Jet Fusion jets fusing and detailing agents onto a nylon powder bed, then an infrared pass melts the slice. Parts come out dense and fairly isotropic, which is why MJF is a common choice for clips, enclosures, and short-run end-use plastics.
AIHFABS nests many part numbers in one cake to drop unit cost. Dye and vapor smooth are the usual finish steps; inserts are added when the same hole will be assembled more than once.
The listed envelope is the planning box. Instant quote still depends on nest density and finish.

±0.3 mm or ±0.3%
380 × 284 × 380 mm
Fine grain; dyeing and vapor smoothing available
Powder bed — no separate support structures
PA12 is the workhorse. TPU and glass-bead filled PA12 are quoted when flex or stiffness needs them.
Natural MJF gray is fine-grained. Black dye is the usual customer-facing step.
Fine as-fused grain, typically gray PA12. Good for internals and shop trials.
Immersion dye for a uniform dark skin that hides the open grain.
Chemical smooth for a less chalky feel on grips and consumer-facing covers.
MJF and SLS share the no-support nylon idea. FDM is cheaper for bulky mock-ups; SLA is smoother for show models.

A carriage jets fusing and detailing fluids onto the powder surface.
Infrared energy fuses the selected regions; the bed lowers and new powder is deposited.
Nested parts share one build for efficient manufacturing lots.
Parts are cooled, depowdered, and finished with dye, tap, or vapor polish as specified.
We pack the cake for a stable fuse and a sane cool-down. Escape holes and even walls are checked in DFM.
Depowder, blast, then dye or vapor smooth only if the order lists them. Thread inserts are fitted after the cake, not printed as a hope.
Uniform walls and a powder exit keep both strength and cosmetics predictable.
| Feature | Recommended practice |
|---|---|
| Walls | Keep thickness even on large PA12 panels to limit sink and warp. |
| Threads | Specify inserts or helicoils when the joint will be assembled often. |
| Nesting | Combine part numbers in one cake when you can — that is how unit cost drops. |
| Escape holes | Open closed volumes so powder can leave after the fuse. |
Selective Laser Melting (SLM) is a powder-bed metal additive process. A high-power laser scans each cross-section of your CAD model, melting metal powder that solidifies into a dense part.

Yes, flexible TPU grades for grips, gaskets, and living features — confirm the durometer on the quote.
No separate support trees. Powder holds the part; you still need escape holes.

查看完整工艺说明Use these process-specific checks when preparing your model, drawing and quote request. The confirmed quotation and approved drawing define the requirements for your part.
Choose the exact supported grade for stiffness, impact behavior and service environment. Avoid assuming that all PA12 parts share identical properties across processes. Thin walls, ribs and abrupt mass changes need review for cooling behavior and dimensional stability.
Build packing and orientation are manufacturing decisions that can affect the schedule and part behavior. Define cosmetic faces and the required color before selecting dyeing or smoothing. Leave access for powder removal in ducts and internal volumes.
Confirm grade, color, surface treatment and finished-part tolerances. For repeat orders, keep the approved revision and acceptance sample, and identify fit-critical dimensions that need measurement.
