What Is Multi Jet Fusion?

Multi Jet Fusion is a new 3D printing technology, offering you more possibilities for complex, lower-cost parts.

Whether used in serial production for single parts or batch manufacturing by shipsets of multiple part numbers, Multi Jet Fusion offers a faster, more cost-effective process for 3D printed parts.

Multi Jet Fusion is ideal for hidden applications like complex thin-wall ductwork, connectors, non-cosmetic housings, brackets, covers, wiring clips, guides and grommets.

Industries like transportation can take advantage of the higher volumes possible with this technology, especially for limited run, pre-production and spare parts.

How Multi Jet Fusion Lowers Costs 

The Multi Jet Fusion process is ideal for building in batches to achieve lower unit pricing, while adding increased functional design complexity. Material costs are associated with part volumes, not part extents volumes, saving costs when compared to Laser Sintering or CNC Machining.

Manufacturing cycle-time for Multi Jet Fusion is driven by the height of the particular batch of parts being printed. Nesting parts together in a single batch is the way to reduce the average cycle-time per unit.

 

Improved Performance with Multi Jet Fusion

Multi Jet Fusion delivers repeatable, isotropic mechanical properties with greater strength and higher accuracy than Laser Sintering.

How Does Multi Jet Fusion Work?

The Multi Jet Fusion process starts with a layer of material applied to the work area.

In the opposite direction, in one continuous pass, the machine prints fusing and detailing agents across the full working area.

This pass combines the printing with the fusing energy, and the process is completed.

The innovative technology prints quickly along the bed width, enabling extreme precision and dimensional accuracy.

Multi Jet Fusion Materials

Multi Jet Fusion currently offers Nylon 12 (PA 12), a strong thermoplastic material well-suited for high-volume functional prototyping and low-volume production applications.

PA 12 is just the beginning of what promises to be an extensive suite of material offerings. Stratasys Direct Manufacturing will be at the forefront of introducing new Multi Jet Fusion materials to our customers.

Frequently Asked Questions About Multi Jet Fusion

What geometries are best suited for MJF?

MJF is ideal for components with complex geometries, including parts with internal cavities. Parts that are produced with MJF remain encased in powdered material, which is self-supporting.

What level of detail can be obtained with MJF?

Typical Multi Jet Fusion layer thickness is 70 microns (0.003 inch). We recommend all Multi Jet Fusion parts have a minimum wall thickness (or feature resolution) of 0.020”.

What is the largest part size you can make with MJF?

The build envelope for the Multi Jet Fusion machine is 16” x 12” x 16”.

Because of the need to scale parts larger to compensate for in-process material shrinkage and also add a buffer around parts for printing agents, the maximum part size is 14.96” x 11.25” x 14.96”.
