Multi Jet 3D printing is an additive manufacturing process enabling the production of highly precise and finely detailed objects. The consistency in the final products and the rapid production process make multi jet fusion a popular 3D printing technology.
It was in the early 90s when multi jet fusion 3D printing was introduced. But initially, it was not much in use because of the lack of production speed compared to metal stamping or injection molding. However, gradually, with technological advancements, the process became more automation-focused. Today, multi jet fusion 3D printing has become a go-to manufacturing solution.
How Does Multi Jet Fusion 3D Printing Work?
In multi jet fusion (MJF), powdered material is fused to form a solid structure using an inkjet array. Here is a detailed description of the multi jet printing process:
The build platform is placed inside the printer. It can move across the X and Y axis.
A thin layer of powder material is spread on the build platform by a recoater carriage.
The powder is preheated to promote material consistency.
The inkjet nozzles eject fusing agents on the material layer as per the geometry of the desired part.
As a layer completes, the build platform moves down for another layer formation.
The process continues until the finished product is accomplished.
Once the printer cools down, the finished object is extracted and excess powder is removed.
Therefore, multi jet fusion 3D printing technology is a hassle-free and easy operation procedure requiring no hard skills!
What are the Top Applications of Multi Jet Fusion?
The production of complex and customized objects with even isotropic mechanical properties has provoked the extensive use of MJF across multiple sectors. These include:
Rapid Prototyping- Designers and engineers rely on MJF as they can transform their ideas into functional prototypes. It reduces the production cost and the lead time exponentially.
Medical Units- For dental implants and prosthetics, multi jet 3D printing is a game changer. You can customize the parts as needed.
Automobile and Aerospace- The products are lightweight and durable, making them an ideal fit for the automobile and aerospace industries.
Architecture- Miniature objects to project models, architects rely on MJF to explore the concept designs.
Times are evolving, and so are manufacturing techniques. No sooner will we witness the dawn of Industry 4.0!
