MJF 3D PRINTING SERVICE
Multi Jet Fusion (MJF) is an industrial 3D printing technology used for the volume production of end-use parts.
Multi Jet Fusion (MJF) is an industrial 3D printing technology used for the volume production of end-use parts.
MJF is a new additive manufacturing technology that uses an inkjet printhead to jet droplets of agents onto a fine layer of nylon powder. Lamps heat the agents, fusing particles of plastic powder to build parts one ultra-fine layer at a time. MJF produces highly accurate, functional parts with fine details, sharp edges and a smooth surface. No support structures are needed enabling complex geometries.

Multi Jet Fusion (MJF) operates by spreading a fine layer of nylon powder within the build chamber. The MJF 5210 3D printer uses print heads to jet detailing and fusing agents onto the powder, creating a 2D cross-section of the desired part. Heat lamps then activate the agents, fusing the PA12 nylon powder into a solid layer. This process repeats, adding new layers of powder to build the 3D part layer by layer.
Yes, 3D prints produced using HP Multi Jet Fusion technology are nearly watertight right after printing. They typically do not require additional post-processing to achieve a high degree of water resistance.
The primary distinction between Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) lies in the method of fusing the powder material into parts. SLS employs a laser for this purpose, while MJF uses agents and heat lamps. Notable differences include the natural grey colour of MJF 3D prints compared to the white colour of SLS 3D prints. Additionally, these technologies utilise different pricing algorithms. For a more detailed comparison, you can refer to our blog post on Selective Laser Sintering (SLS) versus Multi Jet Fusion (MJF).
Multi Jet Fusion (MJF) offers several advantages over other 3D printing technologies. These include high speed, precise printing, the ability to produce functional and durable parts with excellent mechanical properties, and the capability to create parts with fine details and complex geometries. Additionally, MJF typically results in minimal post-processing requirements.
Multi Jet Fusion is suitable for a wide range of industries, including aerospace, automotive, healthcare, consumer goods, and more. It can be used to produce prototypes, end-use parts, custom medical devices, and various components in industries that require precision and durability.
The resolution and layer thickness achievable with Multi Jet Fusion can vary depending on the settings. Generally, MJF achieves a layer thickness of 0.08 millimetres (80 microns), allowing for high-quality and detailed 3D prints. At 3D People we only print on the finest layer height possible with MJF.
While Multi Jet Fusion technology is versatile and can produce parts of various sizes, there may be limitations based on the MJF printer's build volume. The maximum size of parts that can be produced are 370 x 370 x 270mm however we wouldn't recommend printing parts this size if your component requires tight tolerances, or an even surface finish.
