Our MJF 3D Printing Service
Our industry-leading HP Multi Jet Fusion 3D printing services company, offering volume production and prototyping. We have 5 HP MJF machines instead of the more common SLS 3d technology as it is a 3d printing device designed for industrial scale additive manufacturing.
With these machines, we are able to provide the fastest turnaround time, the lowest possible unit price, and more accurate and stronger parts than SLS alternatives. Whether you need one-off prototypes or high-volume end-use parts, our manufacturing facility can deliver strong, precise and durable parts, primarily in nylon PA12.
What is MJF?
MJF stands for Multi Jet Fusion, which is a 3D printing technology developed by HP. It uses a combination of thermal energy and inkjet printing to create parts with high accuracy and detail.
In MJF 3D printing, a layer of powder material is spread onto a build platform, and then an inkjet array selectively applies a fusing agent to the areas of the powder that will become the part. Next, thermal energy is applied to the powder bed, causing the fusing agent to melt and fuse the powder particles together, forming a solid layer. This process is repeated for each layer until the part is complete.
MJF 3D printing is capable of producing parts with high surface quality and fine details, as well as complex geometries and internal structures. It is particularly well-suited for producing small- to medium-sized parts, and is used in a variety of industries including aerospace, automotive, and healthcare.
Advantages of MJF 3D Printing Process
While there are many benefits to MJF printing, a few truly stand out. For starters, the standard build parameters are optimized for the best density. The result is that Multi Jet Fusion parts are watertight.
If you like SLS but want to produce higher quantities for small-batch production runs, Multi Jet Fusion is the way to go. MJF printers have the ability to print multiple parts simultaneously across the entire build volume means you can print parts at rates up to 10X faster than SLS or other 3D printing processes. Also, Multi Jet Fusion delivers more balanced mechanical properties across the X, Y, and Z axes compared to SLS.
Where is MJF used ？
Prototypes
Generate iterations of working prototypes to enhance your designs during product development. Use industrial MJF PA12 nylon to verify functionality before mass production.
- complex geometry
- extremely high precision
- Prototype matching production
End Use Parts
Using industrial grade PA12 nylon and finished in natural grey or deep dye black, MJF printed parts are suited to a vast range of both indoor and outdoor applications.
- Strong and sturdy
- Repeatable properties
- Chemical resistance
Batch Production
Mass production is a core strength of Multi Jet Fusion, and the scale from single part to mass production is seamless.
- No tooling costs
- Scalable mass production
- Dimensional accuracy

Surface Finishing Options for MJF 3D Printing
Surface finishing is important if you want to make your 3D-printed prototypes or production parts stronger, last longer, look better, or even work better. Check out these different ways to finish your project, and you’re sure to find one that works for you.
| Image | Name | Description | Color | Detail |
|---|---|---|---|---|
 | As Printed | Crisp edges and almost no visible layer lines. The surface has a grainy texture, similar to an extra strong mint. | n/a | Learn more >> |
 | Black Dye | Our deep-dye process does not alter the part dimensions. MJF Black Dye 3D prints are black throughout the part. | Black | Learn more >> |
 | Vibro Polished | Remove the grainy texture of MJF parts for a smooth finish. Without additional colouring, the polished grey finish is visually uneven. | n/a | Learn more >> |
 | Dyed & Polished | Polished grey MJF parts can be dyed black. The finish is more scratch-resistant than un-polished black parts. | n/a | Learn more >> |
