Volume Production of High Performance End-Use Parts
Multi-Jet Fusion (MJF) is an advanced manufacturing technology that provides designers unparalleled production flexibility, allowing for cost-efficient customization and batch production at high volumes using 3D printing.
What is Multi-Jet Fusion (MJF) 3D Printing?
Multi Jet Fusion (MJF) is a industrial 3D printing technology that chemically melts powder together to create strong, precise and detailed parts. Primarily used for end-use manufacturing, it is a highly cost-effective solution for low to medium volume production of functional 3D printed parts. MJF eliminates the need for expensive tooling and enables production flexibility, allowing for cost-efficient customization and batch production at high volumes.
This advanced additive manufacturing technology delivers excellent dimensional accuracy and the ability to achieve intricate and fine details. By utilizing detailing agents, MJF enhances the resolution of printed parts, resulting in sharp edges, thin walls, and small features. This level of precision is crucial for designers seeking high-quality, intricate designs, and complex geometries with consistent mechanical properties throughout the the entire part.

HP PA12 Natural Grey
Tough and DurableHP High Reusability PA12 is a highly durable nylon 12 material with excellent surface resolution. PA12 produced using Multi Jet Fusion is very high density (98%) makes the parts highly durable and ideal for creating parts that need to withstand heavy use or exposure to harsh environments. Its high strength-to-weight ratio also makes it a great option for lightweight parts that require a high degree of strength and durability. Parts produced with this material have consistent and reliable quality. This is particularly important for complex parts or assemblies that require a high degree of precision. Parts are watertight and capable of meeting USP Class I-VI and US FDA guidance for biocompatibility.

Why Use Multi-Jet Fusion?
Multi-Jet Fusion builds parts by spreading a thin layer of powdered material across a build platform. Multiple jets then apply two types of liquid agents onto the powdered bed: the fusing agent and the detailing agent. The fusing agent is selectively applied to the areas where the part is to be formed. It helps bind the powder particles together during the subsequent heating process. The detailing agent is applied to the areas requiring fine details and features, enhancing the resolution of the printed part. After the agents are applied, a heating unit passes over the powdered bed causing it to melt and bond the powder particles together. The build chamber is then rapidly cooled to solidify the fused powder and maintain its shape and integrity. This process is repeated for subsequent layers, with a new layer of powder spread and the agents applied according to the digital design specifications.
One of the key benefits of Multi-Jet Fusion is its speed. Unlike other power bed fusion 3D printing methods, MJF utilizes an array of jetting nozzles that simultaneously deposit fusing and detailing agents onto a powder bed. This parallel processing enables rapid manufacturing, reducing production time compared to other techniques. The speed of MJF makes it ideal for quickly iterating and testing designs, accelerating product development cycles as well as producing large volumes of parts for production.
Design Guidelines
HP Multi-Jet Fusion is an new additive manufacturing technology that bridges the gap between 3D printing and injection molding. This design guidelines covers specific design parameters, which will need to be followed to prevent build failures from occurring. We have set the minimum allowed tolerances specified by the engineers from the manufacturer which will need to be followed or your parts may not meet the specific tolerances required or may cause the entire build to fail.
Maximum Build Volume

Layer Height
80 MicronsThe layer height is the overall Z resolution of the part; we avoid stepping artifacts on important features of your models by orienting the part(s) along the Z plane or at a 20 degree angle on all sides. Unless otherwise specified, all SLS parts are printed at a 100 micron layer height.
