What is Multi Jet Fusion?

Multi Jet Fusion (MJF) is a 3D printing technology that produces functional nylon prototypes and production parts in as fast as 24 hours. MJF 3D printing utilizes powdered thermoplastic material to create highly detailed, accurate parts with consistent mechanical properties.

The MJF 3D printing process begins with a layer of fine powder spread across the build platform, onto which a fusing agent is selectively deposited by an inkjet printhead to define the part’s geometry. A detailing agent is then applied to enhance precision, followed by the application of heat to fuse the powder, resulting in highly detailed parts with smooth surface finishes. MJF 3D printing is ideal for small to medium production runs because of its rapid build speed and high repeatability.

Collaborating with Industry Leaders

A Blend of Quality and Precision

MJF 3D printing offers a range of advantages that make it a top choice for precise, efficient, and high-quality additive manufacturing including:

High Precision and Detail: MJF ensures excellent surface quality and intricate detailing, achieving layer thicknesses as fine as 80 microns and dimensional tolerances of ± 0.012 in, ensuring high accuracy.

Fast Production Speed: With a high throughput, MJF 3D printing can produce parts up to 10 x faster than SLS 3D printing, making it ideal for rapid manufacturing and serial production.

Consistent Quality: MJF provides consistent mechanical properties across builds with a repeatability of ±0.3%, ensuring reliable and repeatable results.

Efficient Material Usage: MJF 3D printing with TPU material utilizes up to 80% of the material, significantly reducing waste and making it a cost-effective solution.

Less Shrinkage and Warpage: MJF utilizes a standalone cooling process, reducing the temperature gradients that cause internal stresses relating to shrinkage and warpage.

No Supports Needed: MJF eliminates the need for supports during the printing process, giving designers greater flexibility to create complex geometries and streamlining the post-processing phase.

Layer Thickness

0.08 mm (0.003 in)

Tolerances: For well-designed parts, tolerances of +/- 0.012 in. (0.30mm) plus 0.1% of nominal length for each additional inch can typically be achieved. Note that tolerances may change depending on part geometry.

Warpage: Larger part sizes (>7 in.) and parts with thin features are the most susceptible to warp. We recommend maintaining a uniform thickness of 0.125 in. (3.175mm) to ensure stability.
