Multi Jet Fusion (MJF) is a type of 3D printing technology that uses a process called Masked Photopolymer Jetting (MPJ) to create 3D objects. In this process, a special inkjet print head with a masking layer applies layers of photopolymer resin to a build platform, and a UV light is used to cure the resin layer by layer.
One of the advantages of MJF printing is that it is fast and cost-effective, making it a popular choice for high-volume production runs. It is also capable of producing a wide range of materials, including polyamides (nylon), glass-filled polyamides, and polyphenylsulfones (PPSU). MJF is known for producing parts with good mechanical properties and a slightly rougher surface finish than some other 3D printing technologies, such as PolyJet.
MJF is commonly used in a variety of industries, including automotive, aerospace, and consumer goods, for the production of functional prototypes, end-use parts, and low-volume production runs.
MJF, or MultiJet Printing, is a type of 3D printing technology that uses a bed of powder material as the build platform and jets inkjet printheads to deposit droplets of binding agent on the powder. The binding agent fuses the powder together, creating a solid part layer by layer.
There are several benefits to using MJF in 3D printing:
High accuracy: MJF has a high level of accuracy, making it suitable for producing parts with tight tolerances and fine features.
Good surface finish: MJF produces parts with a smooth and high-quality surface finish, making it suitable for producing parts that will be visible or will require a high level of finish.
Dimensional stability: MJF parts have a high degree of dimensional stability, making them suitable for applications where precision is important.
Wide range of materials: MJF can be used with a wide range of materials, including plastics, metals, and composites.
Fast production speeds: MJF has fast production speeds, making it suitable for high-volume production of parts.
Easy post-processing: MJF parts do not require extensive post-processing, such as sanding or finishing, making it a more efficient process overall.
Overall, MJF is a good choice for those looking for a high-quality and efficient 3D printing process for producing parts with a high level of accuracy and surface finish.
MJF can be used with a wide range of materials, including:
Plastics: MJF can be used with a variety of plastic materials, including nylon, polystyrene, and polypropylene.
Metals: MJF can be used with metal powders, such as aluminum, steel, and titanium, to produce metal parts with high accuracy and surface finish.
Composites: MJF can be used with composite materials, such as glass-filled nylon, to produce parts with enhanced mechanical properties.
Ceramics: MJF can be used with ceramic powders to produce ceramic parts with high accuracy and surface finish.
Overall, the choice of material for MJF will depend on the specific requirements of the application, including the desired strength, durability, and cost of the finished part.

The cost of using Multi Jet Fusion (MJF) 3D printing technology can vary significantly depending on a number of factors, including:
- Material: Different materials have different costs, and the cost of the material will be a significant factor in the overall cost of the parts.
- Size and complexity of the parts: Larger and more complex parts will generally be more expensive to produce than smaller, simpler parts.
- Quantity: The cost of producing parts using MJF tends to decrease as the quantity increases, so producing a large number of parts can result in a lower overall cost per part.
- Post-processing: The cost of post-processing, such as cleaning, debinding, and sintering, can also impact the overall cost of the parts.
Overall, the cost of producing parts using MJF will depend on the specific requirements of the project, and it is difficult to provide a general estimate without more information. It is generally advisable to obtain quotes from multiple 3D printing service providers to get a sense of the cost for your specific project.
