In this blog, we delve into the intricacies of HP Multi Jet Fusion technology, exploring its capabilities, applications, and the impact it has had on the commercial 3D printing services sector.

Understanding HP Multi Jet Fusion Technology

HP Multi Jet Fusion technology represents a leap forward in 3D printing. Unlike traditional methods that build objects layer by layer, MJF employs a unique approach known as voxel-level printing. Voxel, short for volumetric pixel, refers to the smallest unit of a three-dimensional object that can be manipulated independently. By precisely controlling each voxel, MJF enables the production of parts with exceptional detail, accuracy, and Understanding the intricacies of MJF is essential for grasping its transformative impact on modern manufacturing. Let’s delve into the core components and processes that make HP Multi Jet Fusion technology a game-changer in the world of HP Multi Jet Fusion 3D Printing:

Powder Deposition

The MJF process begins with the deposition of a thin layer of powdered material onto the build platform. This powdered material serves as the foundation for building the desired object layer by layer. HP Multi Jet Fusion technology supports a variety of materials, including nylon-based powders known for their strength, durability, and versatility.

Inkjet Printing

One of the key features of MJF technology is its high-resolution inkjet arrays. These arrays precisely deposit fusing and detailing agents onto the powdered layer according to the digital design specifications. The fusing agent plays a crucial role in selectively melting the powder to bind it together, while the detailing agent defines finer features and textures with accuracy.

Fusion and Fusing

Once the powdered layer is selectively coated with fusing and detailing agents, the entire layer is exposed to infrared energy. This exposure causes the fusing agent to selectively absorb the infrared energy, melting the powder particles in the desired areas. As a result, the powdered material fuses together, forming a solid layer that corresponds to the specific cross-section of the digital design.

Recoating and Repeat

After the fusion process, a new layer of powdered material is uniformly spread across the build platform, ready for the next cycle of printing. The inkjet arrays then deposit fusing and detailing agents onto this new layer, and the fusion process repeats. Layer by layer, the object gradually takes shape, with each layer accurately fused to the one beneath it.

Advantages of HP Multi Jet Fusion 3D Printing

One of the most significant advantages of MJF technology is its remarkable speed. Unlike traditional 3D printing methods, which can be time-consuming, HP’s MJF printers can produce parts at an accelerated rate, making them ideal for rapid prototyping and large-scale production.


With voxel-level control, MJF ensures unparalleled precision and accuracy in the fabrication of complex geometries. This level of detail is crucial for industries such as aerospace, automotive, and healthcare, where precision is non-negotiable.

Material Versatility

HP Multi Jet Fusion technology supports a wide range of materials, including engineering-grade thermoplastics and elastomers. This versatility allows manufacturers to produce parts with varying mechanical properties, opening up new possibilities in product design and performance.


Whether it’s producing a single prototype or thousands of production parts, MJF offers scalability without compromising quality. This scalability makes it a preferred choice for businesses looking to streamline their manufacturing processes and reduce time-to-market.
