What is MJF 3D printing, or Multi Jet Fusion?

Complex three-dimensional models may be printed very quickly and accurately using this method of 3D printing. In this article, we will examine the benefits of MJF 3d printing service and how it compares to similar methods.

Guidelines for 3D Printing with MJF Files

MJF 3D printing is a Powder Bed Fusion (PBF) method, like SLS (Selective Laser Sintering), that employs a heat source to fuse particles inside a build chamber filled with thermoplastic powder (often nylon or TPU). However, unlike SLS, Multi Jet Fusion does not need a laser to complete its process. Instead, infrared radiation and a fusing agent are used to create the individual layers of the component. With layer heights of about 80 m, MJF 3d printing service is somewhat quicker than SLS while maintaining mechanical qualities and surface finishes on par with SLS. After the build plate has been coated with powder by a recoated, the printer’s ink heads may begin laying down the first layer. They achieve this by drawing the layers of the components as they move through the powder and selectively jetting a fusing agent onto the powder. 

For even more sharpness, a detailing compound is sprayed around the perimeter of the objects. The magic occurs when the print heads deposit the fusing and detailing agents, and then a heat light freezes and consolidates the regions where the agents are present. The build platform moves downwards a short distance, and powder is reapplied in a thin layer over the previously applied powder. All layers must be built up in this manner. After printing, the operator must transport the components to a post-processing unit, which will undergo semi-manual cleaning. The leftover powder may be reused in future construction projects. Bead blasting follows the depowering procedure to clean the components further. A high-pressure stream blasts Fine glass beads onto the components to enhance the surface quality and remove any leftover powder.

How Does It Work

By applying fusing and detailing chemicals selectively over a bed of nylon powder, the 3D printing method known as multi jet fusion 3d printing bonds the powder into a solid functional component in thousands of layers using heat. Allows for the rapid production of complex pieces made from powdered thermoplastics with high accuracy and detail.

The items produced using this technology are stronger and lighter than those produced using traditional 3D printing. In addition, it’s more accurate than other forms of 3D printing, so it’s great for generating things like complicated tools or detailed sculptures.

Which Advantages Are There?

  • Compared to traditional 3D printing methods, avail of robust MJF 3d printing services offers many benefits. One advantage is that it can mass-produce different parts without lowering quality or precision.
  • Unique structural components or functional prototypes may be made by fusing and detailing ink on the powder bed. MJF is an excellent engineering thermoplastic for producing long-lasting, chemical-resistant, and functional components.
  • MJF is a flexible printing method that may create intricately detailed items with complicated geometry. Printing several components at once makes this technology ideal for industrial-scale manufacturing.


MJF technology 3d printing is set to change manufacturing shortly as its number of uses grows.
