Multi Jet Fusion FAQs

What is the surface quality of parts produced by the MJF process, and do they require post-processing?

When designing, consider the limitations related to support structures and minimum wall thickness. It is recommended to avoid excessive overhangs and large horizontal surfaces.
What is the surface quality of parts produced by the MJF process, and do they require post-processing?

Parts produced by the MJF process typically have high precision and detailed features. The surface quality is relatively good, but post-processing may be required depending on the design orientation to further improve it.
What are the advantages of the MJF process?

The MJF process is characterized by its fast manufacturing speed and efficiency. It can produce complex internal structures, and the manufactured parts generally have superior surface quality and mechanical properties.
What applications are suitable for the MJF process?

The MJF process is suitable for rapid prototyping, small-match production, and applications requiring complex internal structures. For example, intricate mechanical parts and industrial components.
What materials are suitable for the MJF process?

The MJF process typically uses nylon and other plastic materials. These materials have good strength and flexibility, making them suitable for mechanical parts, prototype production, etc.
What are the differences between MJF and SLS?

- Both MJF and SLS are high-precision industrial technologies that do not require support structures, suitable for one-time 3D printing of complex movable samples. MJF offers a better overall appearance due to its inkjet heads operating at 1200 DPI (about 0.022mm per unit) compared to SLS's laser spot of about 0.3-0.4mm.

- The detailing agent used in non-printing area of MJF helps enhance the 3D printing features and sharp edges, but MJF is more prone to warping compared to SLS.
What is the principle of MJF process?

The MJF process involves spreading a layer of powder on the print bed, then selectively spraying a fusing agent in the areas to be printed and a detailing agent in the non-print areas to prevent sintering. Infrared light then fuses the material in the desired areas. This process is repeated layer by layer to complete the 3D print.
