Procedure of the MJM process

  1. The Multi Jet Modeling (MJM) process, also known as PolyJet technology, is characterized by a precise and detailed printing process. The process is structured as follows:

    • Preparation of the 3D model data: Digital designs are segmented into thin layers in software to prepare them for printing.
    • Printing process:
      • Applying the resin: An MJM printer applies liquid photopolymer resin to the build platform in layers.
      • Curing by UV light: Immediately after application, the resin is cured by UV light, making each layer solid.
      • Build up layer by layer: This process is repeated for each layer until the object is completely built up.
    • Multi-material printing: MJM enables simultaneous printing with different materials to produce objects with varying properties in a single printing process.
    • Post-processing: Post-processing often follows in order to optimize the surface quality and remove support structures that were required for printing complex geometries.

    This process enables the production of prototypes and end products with exceptional attention to detail and a variety of material properties.

Multi Jet Modeling (MJM) in detail

Who is the MJM procedure suitable for?

  • Designers, engineers and manufacturers: Ideal for creating high-precision prototypes with fine details and smooth surfaces.
  • Industry-specific use:
    • Medical technology: For customized medical devices and implants.
    • Automotive engineering: development of complex components and prototypes.
    • Aerospace: production of lightweight, high-strength parts.
    • Consumer goods sector: production of customized, detailed products.
  • Projects with specific material selection: Suitable for flexible, transparent or multi-colored components within a component.
  • Research and development teams: Developers of innovative products with special mechanical, optical or thermal properties benefit from the flexibility and high precision offered by MJM.

Requirements for Multi Jet Modeling

  • High-quality 3D data: A detailed digital representation of the object to be printed, ideally in a high-resolution format, is essential for the success of the printing process.
  • Understanding the materials: A sound knowledge of the available printing materials and their specific properties helps to select the right material for the respective project.
  • Design adjustments: Designs may need to be adjusted to meet the requirements of the MJM printing process, particularly in terms of support structures and minimizing material usage.
  • Post-processing capacities: The ability to carry out post-processing operations such as removing support structures and polishing surfaces is necessary to achieve the desired end product quality.

By meeting these requirements, users can take full advantage of the MJM process and produce high-quality, customized parts and products.

FAQ about Multi Jet Modeling

MJM is a 3D printing process that applies fine layers of liquid photopolymer resin and cures immediately with UV light to create precise and detailed models.

In contrast to processes such as FDM or SLS, which melt or sinter material layer by layer, MJM enables printing with multiple materials in a single process and achieves very smooth surfaces and complex geometries with fine details.

The cost can vary depending on the size, complexity of the part and materials used. In general, MJM prints are in the higher price segment due to the high-resolution level of detail and the possibility of using different materials.

Designs for MJMs should take into account the ability to create complex geometries and cavities, while also considering the need to remove support material and material properties.
