### What is Multi Jet Fusion (MJF)?

HP **Multi Jet Fusion (MJF)** technology is an advanced additive manufacturing (3D printing) process that uses a combination of fusing and detailing agents, heat and energy, to produce parts and components with exceptional precision and superior mechanical properties.

![Multi Jet Fusion - What is MJF - Ineo](https://www.ineo.es/media/com_sppagebuilder/placeholder/technologies-multi-jet-fusion-ineo-what-is.jpg)

### How does it work?

Starting from the 3D geometry, with the HP 3D printing preparation software, the file is loaded and prepared for printing, adjusting the orientation of the model, and the printing parameters are configured.

The powdered thermoplastic material that the HP Multi Jet Fusion uses as a base for printing is loaded into the build unit and then loaded into the printer.

The printing process begins by applying a thin and uniform layer of powder over the building area. Next, a fusing and detailing agent is applied defining the printing area of the layer.

After applying the fusing and detailing agent, an infrared light applies temperature fusing the defined printing areas in the powder layer, bonding the particles together and allowing them to solidify into the desired shape.

When the current layer fusion is complete, the process is repeated by applying a new layer of powder over the upper top, applying the fusing and detailing agent, and fusing the specific areas. This cycle is repeated layer by layer until the entire printed object is completed.

The construction chamber is then allowed to cool, or the cooling process is accelerated in a controlled manner, to subsequently continue with the extraction and cleaning of the unfused powder, eliminating excess material. Anything not used can be recycled and reused in future prints.

Depending on the design requirements and the end use of the printed object, some additional post-processing may be performed, such as sanding, fitting, painting, or coating.

### Advantages of Multijet Fusion

Some of its advantages are:

- High printing speed
- Excellent dimensional resolution
- Ability to print on a wide range of thermoplastic materials
- Ability to produce parts with superior mechanical properties
- Parts with excellent mechanical resistance
- Finished surface that facilitates post-processing
- Complete design freedom: no supports, dust supports the piece
- Option to nest pieces (one inside another)
- Material structure is “watertight” therefore, no need for post-processing surface treatment

### Aspects to consider

Some considerations regarding this technology:

- Limited building size compared to other technologies
- Slightly rough surface appearance
- Need for a cooling and cleaning process for parts
- Possible deformations in very large pieces
