Multi Jet Fusion
The HP Difference
Multi Jet Fusion (MJF) is the next level of industrial additive manufacturing technology. SLS production parts are built layer by layer by sintering thermoplastic material. The HP difference is the energy source, SLS requires a laser to scan and sinter each cross section, MJF dispenses a fusing agent onto the powder that is absorbed under infrared light.
The technology in more detail
A layer of powder is spread across the build platform and warmed, close to sintering temperature. Step two draws from experience in the 2D sector – a carriage with HP ‘Pagewide’ inkjet nozzles passes over the bed, releasing fusing agent onto the whole layer of powder in less than 7 seconds. A high powered energy source passes over the bed and sinters the areas where the fusing agent was dispensed. This process repeats until the printed part is complete.
Once the build finishes, the entire powder bed containing the encapsulated parts is transferred to the processing station. Just like the SLS process, completed parts are encapsulated in powder and need to cool down before they can be removed and finished.
– Shorter lead times
Unlock production additive manufacturing opportunities with improved build times, greater reliability and greater throughput. Many thousands of parts can be manufactured in just one 12 hour print build, making it ideal for volume production runs of ‘end-use’ parts.
– Stronger parts
The HP Jet Fusion build process is self supporting and therefore negates the need for complex support structures during the build process. Highly detailed parts, with complex internal geometries can be built with ease.
