HP Multi Jet Fusion is a powder-based technology that doesn’t use lasers. Instead, it works with fusing and detailing agents that are jetted where particles need to be selectively molten. Take a look at the illustration below to see how it works. HP Multi Jet Fusion currently uses a fine-grained PA 12 material which is capable of ultra-thin layers of 80 microns. (If you’re curious about the material’s technical specifications, check out the datasheets for PA 12 MJF.)

So what kind of parts is HP Multi Jet Fusion best for? Giovanni Vleminckx, our research engineer who’s been working on the HP Jet Fusion 3D 4200 ever since Materialise received the first one in November, says the technology has excellent surface quality owing to the thinness of the layers.
 

“It’s perfect for projects that need surface texturing or high detail. Think in terms of functional parts, parts that need printed labeling, engraving, embossing, or just thinner walls than you’d get with other versions of PA 12.”

During our benchmarking and testing, we also found that parts produced with HP Multi Jet Fusion have high isotropy and low porosity. In many other respects, you may find the properties and applications to be similar to those of Laser Sintering.
