    Multi Jet Fusion is a unique type of industrial 3D printing method that

    produces nylon prototypes. The highly regarded 3D printing technology utilizes PA 12. Multi Jet Fusion technology will be ideal for excellent surface texturing.

    Let’s discuss Multi Jet Fusion 3D printing in detail.

    How It Works

    Typically, Multi Jet Fusion 3D printing uses an inkjet to apply detailing agents on nylon powder.

    The nylon powder is combined with heating elements to form a solid layer. This is followed by powder after every layer. The user repeats the process until the whole part is complete.

    It is worth noting that the powder bed is moved to a processing section specifically when the build finishes.

    In most cases, most of the loose powder is removed with a vacuum. To remove the excess residual powder, all the parts are blasted days before reaching the finishing section.

    Once the parts reach the finishing department, they are dyed. The main reason for dying the parts is to improve the overall appearance.

    Uses of Multi Jet Fusion

    For years now, Multi Jet Fusion has been used to make nylon prototypes. Multi Jet Fusion is praised for its quality surface finishes.

    In addition, it guarantees consistent mechanical properties compared to other popular processes such as laser sintering.

    The most notable thing about Multi Jet Fusion is that it can produce complex and other detailed features.

    Keep in mind that proto labs will provide you with commercial-grade nylon material. Furthermore, this technology offers users advanced ways to produce parts on demand.

    The Future of Multi Jet Fusion 3D Printing

    There is no doubt that 3D printing is creating a new world of manufacturing. People can now come up with complex parts with precision.

    Reasons You Should Choose Multi Jet Fusion for Your Project

    Nowadays, people prefer using this technology because it provides high-grade materials with amazing overall properties. Besides, Multi Jet Fusion offers finer features and consistent mechanical properties. With 3D printing, services such as post-machining are done professionally.

    Multi Jet Fusion plastic is still considered the perfect choice for different applications. The strength and durability of Multi Jet Fusion make it the ideal choice for RC car parts. This technology is currently being used in home décor.

    Qualities that Multi Jet Fusion Offers

    It’s a skin-friendly plastic material with a record deflection of 95 degrees Celsius. In addition, it provides good chemical resistance.

    Multi Jet Fusion Applications

    It is no secret that Multi Jet Fusion is an excellent fit if you want to build a durable part with complex details.

    Living hinges and end use production are currently some of the most popular uses of Multi Jet Fusion applications. Durable end-use products are being made with 3D printing. Additionally, it is used in games and eyewear.

    Functional parts that need extra strength and high accuracy are made with 3D printing. Research has also shown that applications such as drones and housing cases utilize Multi Jet Fusion technology.

    Difference between Multi Jet Fusion and Selective Laser Sintering

    The two processes have a lot in common. While selective laser sintering relies on laser, Multi Jet Fusion focuses on inkjet heads. Unlike selective laser sintering, a detailing agent is used in Multi Jet Fusion. The only comparable thing about the two processes is actual print time.

    Another crucial thing to note is that the Multi Jet Fusion has fine print heads compared to selective laser sintering. This means that Multi Jet Fusion results in fine details and sharp edges.

    Last but not least, selective laser sintering is white which allows the dying of finished parts. Multi Jet Fusion on the other hand is gray in color. The finished options must be gray and black.

    All in all, selective laser sintering and Multi Jet Fusion are used in building durable and functional parts. The biggest difference between the two processes is the mechanical properties.

    The Types Of 3D Printing

    1. Stereolithography (SLA) 
    2. Selective Laser Sintering (SLS): (check out the best SLS 3D printers)
    3. Digital Light Processing (DLP)
    4. PolyJet 3D printing
    5. Multi Jet Fusion (MJF)
    6. Electron Beam Melting (EBM)
    7. Direct Metal Laser Sintering (DMLS)
    8. Binder Jetting (BJ) Technology
    9. Drop on Demand (DOD)
    10. Fused Deposition Modelling (FDM)

    Final Thoughts

    Multi Jet Fusion is type of 3D printer– it’s technology that has been developed by HP. It is a unique type of industrial 3D printing method that produces nylon prototypes. The highly regarded 3D printing technology utilizes PA 12, which is known for its excellent surface texturing and high strength-to-weight ratio.

    Multi Jet Fusion printers are designed to work with an array of colors and materials, including metals, composites, and translucent plastics. This will allow businesses to create a variety of products using one machine – from functional parts and medical devices to eyewear and car parts.

    After reading the above article, you can see that the 3D printing technology is accurate and durable. The manufacturing method was made and invented by HP Company. Multi Jet Fusion produces high-quality and precise 3D objects.
