MJF

MJF – Multijet Fusion

MJF is a modern 3D printing technology developed by HP, specifically designed as an industrial production technology. This technology is characterized by its high speed and precision, making it suitable for producing functional prototypes, final parts, or small series of products. MJF is used in various industries, such as automotive, aerospace, healthcare, consumer goods, and electronics.

MJF Printing Process

The process begins by applying a thin layer of powder, usually plastic, onto which agents are precisely deposited using nozzle heads over the defined area. After applying the agents to the powder layer, infrared heat is used. The heat causes the areas treated with the binding agent to fuse (melt), forming a solid layer of material, while the untreated areas remain in powder form. This process is repeated layer by layer until the final part is created.

Advantages of MJF technology:

• High precision and detail: Allows the creation of complex geometries with fine details.
• High printing speed: MJF enables rapid production of parts in series, reducing overall production time.
• No need for support structures: Facilitates printing of complex shapes without additional materials.

Most common uses:

• Rapid prototyping: For testing designs and product functionality in a short time.
• Production of small to medium series: Ideal for parts with high precision and quality demands.
• Consumer goods and electronics: For manufacturing covers, grips, and other components where surface quality and detail are essential.

Available materials: 

PA11, PA12, TPU

Fun Fact:

MJF technology allows the printing of parts that are directly assembled and functional, without the need for subsequent assembly. This means you can print transmissions or other mechanical assemblies that are ready for use immediately.
