Industry-leading in-house production services
Operated from our dedicated production facility, our HP Multi Jet Fusion 3D printing service offers both volume production and prototyping services. We chose the HP MJF machine over the more common SLS 3D technology because it was designed from the outset for the huge growth in 3D printing manufacturing, providing speed and efficiency for industrial-scale additive manufacturing.
With in-house production facilities, we are able to offer the fastest turnaround, lowest unit price, and more precise and stronger parts than SLS alternatives. Whether you need a one-off prototype or a high-volume end-use part, our manufacturing facility can deliver strong, precise, and durable parts, primarily in Nylon PA12.
Alternatively, our team of engineers can guide you through the deployment of your additive design from concept to final production, providing you with highly personalized guidance. By providing engineering support, we can create new design options to improve performance and efficiency or reduce weight.

What is Multi Jet Fusion
HP Multi Jet Fusion (MJF) is a powder bed fusion 3D printing process similar to Selective Laser Sintering (SLS). Instead of using a laser as a heat source (like SLS), MJF uses HP’s proprietary inkjet technology to fuse layers of powder. This advanced 3D printing technology selectively applies fusing and detailing agents to deliver and control the thermal energy of infrared heating lamps. The build process is repeated for each layer of powder until the part is printed. Each layer of powder acts as support, so complex parts with lattice structures, overhangs, and undercuts can be produced without support structures.
After the build cycle is complete, the part is moved to a machining station to cool and an integrated vacuum is used to extract most of the loose powder. The part is then sandblasted to remove any residual powder. Finishing and post-processing techniques can then be applied to improve the appearance and performance of MJF parts, such as surface smoothing, DeepDye coloring, engineered coatings, or heat-set inserts.
MJF produces resilient end-use parts and functional prototypes with excellent resolution, surface finish, and edge definition. HP Multi Jet Fusion 3D Printing is ten times faster than Selective Laser Sintering, enabling production-grade manufacturing and customization without expensive tooling.
Increased Competitive Advantage Throughout Product Life Cycles
The high speed and low cost of Multi Jet Fusion 3D printing makes it possible to add value at every stage of your product life cycles. Beginning with product development, MJF can quickly print functional prototypes and proofs of concept, allowing you to take your product through more iterations in less time and get to market even faster. This developmental advantage also translates to other manufacturing technologies: MJF can create durable tooling for thermoformed or cast urethane parts in a fraction of the time and cost of traditional methods.
It’s not just prototypes—MJF is an excellent choice for initial production runs or other low-volume manufacturing. Because of their unique design possibilities, 3D printed parts allow manufacturers a variety of opportunities to decrease cost and improve functionality, whether by combining multi-piece assemblies into single parts, reducing part weight with internal lattice structures, or using just-in-time manufacturing to reduce inventory and overhead.
HP MJF Build & Design Guidelines
HP MJF offers amazing part details, but each 3D printing technology ranges on what size features it can build see below for best standard practices
- Build Layers = 80 microns (0.003”)
- Minimum Walls Thickness & Feature = 0.5mm or 0.020”
- Standard Finish = Level 2 Finish with bead blast (available custom finishes)
- Standard Lead Time = 3-5 days
- Tolerances = +/- 0.010” for first inch then +/- 0.003” per inch thereafter
- Inserts = Install in post-processing
- Holes = Drill, Ream, and Tap (Print threads then chase or ream in finishing)
The Fastest 3D Printing
Don’t let its size fool you: the HP Multi Jet Fusion is the fastest 3D printer on the block, with industry-leading production speeds up to 50 times faster with printing materials than other 3D printing technologies land cost reductions of up to 50% in comparison to SLS and FDM.
In addition to being cheaper and faster, HP Multi Jet Fusion 3D printing offers superior surface finish, detail resolution, and strength when compared to ColorJet, selective laser sintering (SLS), fused deposition modeling (FDM), and stereolithography (SLA).
Whether you are in product development, Low volume manufacturing, or product maintenance Elimold and HP Multi Jet Fusion printing with fusion technology will provide measurable benefits to your production on the first run.
