    How does MJF technology work?

    1. The recoater carriage travels across the build area despositing a uniform thin layer of powder material.

    2. The printer’s ink heads selectively eject a fusing agent, drawing the layers of the parts as they pass, and detalling agent around the edges of the objects to increase their resolution.

    3. Aheat lamp solidfies and consolidates the areas where the agents are present.

    4. The build plate descends slightly and the powder recoater applies another thin layer of powder on top of the layer.

    Q&A

    What are the advantages of MJF 3D printing?

    MJF is known for its high-speed printing capabilities. It can build parts at a faster rate compared to some other 3D printing technologies. MJF supports a range of materials, including nylon-based powders. This versatility enables the production of parts with different mechanical and thermal properties, expanding the range of applications for MJF-printed components.

    What materials are used in MJF technology?

    In MJF, the materials used are typically powders that are selectively fused together layer by layer to create 3D-printed objects. The primary materials used in MJF technology include: Polyamide (PA) 12, HP 3D High Reusability PA 11, HP 3D High Reusability TPA enabled by Evonik, Ultrasint®  TPU01 for HP Jet Fusion Printers, HP 3D High Reusability PP enabled by BASF.

    What the Multi Jet Fusion 3D printing process looks like

    The recoater carriage travels across the build area despositing a uniform thin layer of powder material. Than The printer’s ink heads selectively eject a fusing agent, drawing the layers of the parts as they pass, and detalling agent around the edges of the objects to increase their resolution.The next step is Aheat lamp solidfies and consolidates the areas where the agents are present. The build plate descends slightly and the powder recoater applies another thin layer of powder on top of the layer.

    What are the characteristics of the prints in the MJF?

    MJF can achieve fine layer resolutions, typically in the range of 80 to 120 microns. This allows for detailed and precise prints. MJF can achieve fine layer resolutions, typically in the range of 80 to 120 microns. This allows for detailed and precise prints.

    What are the applications of Multi Jet Fusion?

    MJF allows designers and engineers to quickly iterate and test designs before moving into full-scale production. MJF is suitable for low to medium volume production of customized or specialized parts, automotive industry, aerospace industry, medical applications, consumer goods, MJF is utilized in the production of jigs and fixtures used in manufacturing processes.
