Multi Jet Fusion is an advanced industrial 3D printing technology that creates functional nylon prototypes and production-ready parts in as little as one day. This process delivers high-quality surface finishes, precise feature details, and more consistent mechanical properties compared to methods like selective laser sintering.
Typical applications of Multi Jet Fusion include:
Our fundamental guidelines for Multi Jet Fusion highlight key design factors to optimize manufacturability, improve aesthetic quality, and minimize production time.
| US | Metric | |
| Maximum Part Size | 11.1 in. x 14.9 in. x 14.9 in. | 284mm x 380mm x 380mm |
| Layer Thickness | 0.00315 in. | 80 microns |
| Minimum Feature Size | 0.020 in. | 0.5mm |
| Wall Thickness | 0.020 in. | 0.5mm |
Tolerances: Well-designed parts can generally achieve tolerances of ±0.012 in. (0.30mm), with an additional 0.1% of the nominal length per inch. However, tolerances may vary depending on part geometry.
Warpage: Larger parts (over 7 inches) and those with thin features are more prone to warping. To enhance stability, we recommend maintaining a consistent thickness of at least 0.125 in. (3.175mm).
PA 12 Black
PA 12 Black is a durable nylon with high tensile strength. The final parts are dyed black, offering high-quality surface finishes and more isotropic mechanical properties compared to SLS materials. PA 12 provides finer feature resolution (0.02 in) compared to SLS (0.03 in), making it ideal for parts requiring detailed precision. It is also the optimal material choice for designs that include living hinges.
Key Advantages
PA 12 40% Glass-Filled Black
PA 12 40% Glass-Filled Black is a nylon material reinforced with 40% glass content, and the final parts are dyed black. Its main advantage is its heat deflection capability, which reaches 347°F (at 66 psi), making it the second-best option after PA 12 Mineral-Filled in terms of heat resistance.

These values are approximate and may vary based on several factors, including machine settings and process conditions. As such, the provided information is not definitive or certified. For critical performance requirements, we recommend conducting independent lab testing on the additive materials or finished parts.
| Standard | A bead blast removes all powder and leaves a consistent overall texture. Parts are then dyed a standard black color. |
| Vapor Smoothing | Significant reduction of surface roughness from 250+ μin RA (as-printed) to 64 – 100 μin RA after smoothing. Available for PA12 Black. |
| Custom | Secondary options include a primer that can be applied as well as taps and inserts. |
We utilize HP Jet Fusion 3D 4210 and 5210 machines, which offer faster build speeds compared to other powder-based additive manufacturing technologies. These HP 3D printers produce high-quality commercial-grade parts, featuring superior surface finishes and enhanced mechanical properties when compared to other 3D printing technologies.
Discover why Multi Jet Fusion 3D printing is perfect for creating functional prototypes and end-use production parts.
Multi Jet Fusion employs an inkjet array to precisely apply fusing and detailing agents onto a bed of nylon powder. These agents are then fused into solid layers using heating elements. After each layer is formed, more powder is spread across the bed, and the process repeats until the part is fully built.
Once the build is complete, the entire powder bed containing the parts is transferred to a processing station, where most of the loose powder is removed using an integrated vacuum system. The parts are then bead blasted to eliminate any remaining powder before moving to the finishing department, where they are dyed black for enhanced cosmetic appearance.
