What is Multi Jet Fusion / MJF?

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.

Multi Jet Fusion (MJF) Technology

How does MJF work and what is the benefit?

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.

Lower Production 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.
