Multi Jet Fusion or MJF 3D printing is preferred over other 3D printing technologies like SLS, etc. because it can produce highly precise, accurate, and durable products at much lower cost. From prototypes to end-use parts- MJF is used for the production of a wide variety of products.

MJF technology 3D printing is extensively employed for small-batch to mid-sized production series. Rigid plastics like nylon PA11, nylon PA12, and PP, while flexible plastics like TPU M95A and Estane 3D are used in multi jet fusion 3D printing.

Though there are several other 3D printing technologies, MJF is unique as it proposes some distinct advantages. We will come to that, but let us first understand how the process works.

Understanding the MJF Printing Process

Multi jet fusion 3D printing uses polymers to produce objects. The process involves:

  1. A thin layer of the powdered material is spread evenly on the build platform.

  2. An inkjet head deposits a fusing agent and detailing agent on the powdered material.

  3. A UV light source moves across the build platform. The layer with the fusing agent melts and forms a shape, while the layer with the detailing agent remains as loose powder.

  4. The build platform lowers, and the process repeats.

  5. Once the process is completed, the final product is removed from the printer.

  6. Removal of excess powder is the final step in the procedure. This powder can be reused further.

Thus, MJF technology 3D printing is a simple yet efficient process to build functional parts and prototypes possessing excellent mechanical properties. 

Benefits of Multi Jet Fusion 3D Printing

MJF 3D printing has enumerated remarkable benefits, proposing it as one of the most unique technologies. Here they are:

  • No Support Structures Required- MJF is an additive manufacturing technology where a product is built layer-by-layer. However, the process does not require additional support structures. All the empty spaces are filled with loose powder while printing, eliminating the need for extra support.

  • Enable Full-Colored Parts Production- A multi jet fusion 3D printer can print parts in full color. It uses engineering standard plastics, enabling the printing of parts in the full-color spectrum without optimizing mechanical properties.

  • Impressive Price-Quality Ratio- The products obtained pose excellent mechanical properties and dimensional accuracy. In most cases, there is no need for post-processing since the parts have a superior surface finish and are already colored. Therefore, the cost of production is low.

  • High-Density Products- With outstanding mechanical and physical properties, you get high-density and low-porosity products. Hence, they are ideal for functional prototypes and end-use products.

  • Minimum Wastage- When speaking of the advantages of multi jet fusion 3D printing, you cannot miss out on its minimal environmental footprint. More than 50% of the material can be reused after production, reducing material consumption.

  • Faster Production- Lastly, MJF has a shorter lead time, making it suitable to produce large volumes. You can print several parts at a go!

So, don’t you think MJF is ideally an exclusive 3D printing technology?
