Advantages of the MJF 3D printing process

The MJF 3D printing process is ideal for manufacturing components that are used in the automotive, electronics and mechanical engineering industries, for example. With the ability to print complex parts without the need for support structures, MJF offers time and cost savings over traditional manufacturing methods.

Procedure of the MJF process

  1. Transmission of the 3D data: The customer sends the 3D model data to be printed to the service provider. This data is checked for printability using software and, if necessary, adapted for optimum production.
  2. Preparation of the printing process: The printer is prepared with the selected powder material, such as polyamide or alumide. The powder is applied evenly to the print bed.
  3. Printing process: The SLS printer heats the powder material to just below the melting point. A laser then sintered the powder particles together at the specified points based on the 3D data. This process is repeated layer by layer until the component is complete.
  4. Removal and cleaning: After printing, the finished component is removed from the powder bed. Excess powder is carefully removed to clean the part.
  5. Post-processing (optional): Depending on the customer’s specific requirements, post-processing can be carried out, for example to achieve a higher surface quality or to improve additional properties of the component.

This process offers a flexible and efficient way to manufacture complex components, minimizes material waste and reduces the need for extensive reworking.

Popular process for product development

Who is the MJF procedure suitable for?

HP’s Multi Jet Fusion (MJF) process is ideal for a wide range of users looking for a fast, flexible and high-quality solution for the production of prototypes through to final products. Ideal for:

  • Innovative companies and start-ups that need fast iterations and accelerated product development to secure a competitive advantage.
  • Industrial designers and engineers who want to realize complex components with fine details and high mechanical strength.
  • Manufacturers in the automotive, aerospace and medical technology sectors who require robust, functional parts with specific material properties, such as high temperature resistance or biocompatible materials.
  • Small batch manufacturers looking for a cost-effective solution for the production of small quantities without the need for expensive tools.

Requirements for the MJF procedure

  • 3D model data: The basis for every print job is digital design data, preferably in a format optimized for 3D printing such as STL or OBJ.
  • Understanding of material properties: A basic understanding of the different materials used in MJF and their properties is crucial in order to select the right material for the specific requirements of the project.
  • Design customization: Adapting the design to the 3D printing process, including consideration of wall thicknesses, overhangs and part orientation, maximizes the quality and functionality of the printed object.

With PROTEC3D as your partner, you benefit from comprehensive support and advice to fulfill these requirements and successfully implement your projects using the MJF process.

Frequently asked questions about MJF

HP Multi Jet Fusion (MJF) is an advanced 3D printing technology developed by Hewlett-Packard that produces high-precision, functional parts at speeds that are often faster than other 3D printing processes. This technique enables the production of objects with uniform mechanical properties, a high level of detail and an excellent surface finish. MJF is particularly suitable for the production of prototypes and end parts in small to medium series and can process a wide range of materials, including various plastics.

  • The printing time depends on the size and complexity of the component and the utilization of the pressure chamber. In general, however, MJF enables faster production compared to other 3D printing technologies, especially when manufacturing large quantities.

Multi Jet Fusion works by selectively applying fusion and detailing agents to a powder bed of thermoplastic material. The basic process involves applying a thin layer of the powder material to the work surface. A print head, similar to those used in conventional inkjet printers, then applies the agents to the specific areas of the powder bed. A fusing agent promotes the fusing of the powder, while a detailing agent is used to define the contours and details by preventing fusing in the areas treated with it. The application of the agents is followed by a heat treatment that melts the material where the fusing agent was applied, thus building up the objects layer by layer. This precise and controlled application of the agents and subsequent heat treatment enables MJF to produce parts with complex geometries, high density and excellent surface quality.

  • MJF is characterized by an efficient use of materials, as the powder can be recycled and reused, which reduces the amount of waste. However, the energy efficiency and carbon footprint of the process depend on the specific application and the scale of production.
