ProtoCAM: Additive Manufacturing, 3D Printing and Rapid Prototyping.

Multi Jet Fusion

ProtoCAM utilizes HP’s Multi Jet Fusion (MJF) technology to produce quality, functional parts at a production speed that is up to 10 times faster than competing processes. Unlike the slower point processes of some other current technologies, MJF technology processes parts in two fast area-wide passes to achieve top-speed part production.

About Multi Jet Fusion

MJF printing technology reinvents how we prototype and produce functional parts, delivering quality output, up to 10 times faster and at reduced cost.

The process begins by applying a layer of material in a work area. In the opposite direction, in one continuous pass, we print fusing and detailing agents across the full working area. This pass combines the printing with diffusing energy and the process is then completed. HP’s proprietary architecture is capable of printing 30 million drops/second along every single inch of bed width, enabling extreme precision and dimensional accuracy.

To produce truly functional parts, it’s important to ensure that the material has been properly fused and that part edges are smooth and well-defined. To achieve part quality at speed, HP invented a multi-agent print process. In the time it takes slower point processes, like material extrusion and laser sintering, to build 1,000 parts – MJF technology would have created several thousands of parts. Using HP’s proprietary multi-agent printing, the MJF technology achieves new levels of part quality at breakthrough speeds.

In 3D design and printing, a voxel represents a value on a regular grid in a three-dimensional space. By controlling the processes of each individual voxel through agents, MJF can produce parts that can’t be made by other methods.

Though this print style has been compared to selective laser sintering, it works in a completely different way, fusing layers of powder in one pass, while SLS works by sintering each individual part. This means that MJF technology can produce more parts faster, resulting in increased throughput and higher production quantities.
