Multi Jet Fusion is an industrial 3D printing technology that produces functional nylon prototypes and end-use production parts in as little as 1 day. The final parts exhibit superior surface quality, higher feature resolution and more consistent mechanical properties compared to technologies such as SLS.
Multi Jet Fusion technology is a 3D printing technology based on inkjet technology as in 2D printers. In this technology, which provides layer-by-layer production, powder material is used on the production table. Multi Jet Fusion is a powder-based technology but does not use lasers.
HP MultiJet Fusion uses a fine-grained material that allows ultra-thin layers of 80 microns. This enables parts with high density and low porosity to be produced compared to parts produced by Laser Sintering. It also provides an exceptionally smooth surface straight out of the 3D printer and requires minimal 3D printing post processing for functional parts. This means short lead times and what’s more, it is ideal for functional prototypes and small parts.
Multi Jet Fusion 3D Printing Process
MJF 3D Printing
The production process starts as in other 3D printers, the 3D model is displayed in the relevant software program and made ready for printing. The powder bed of the HP jet fusion 3D printer is preheated and the polyamide material is laid as a thin layer from the powder bed to the production chamber. According to the selection of the particles, a fusion agent is sprayed at the place that needs to be melted, and a detailed agent is thrown around the contours to increase the resolution of the part. As the lamps pass over the surface of the powder bed, the sprayed material captures the heat and helps distribute it evenly. Thus, layer-by-layer production begins and this process continues until the 3D model is completed. Made of 3D Printer, this model is left to cool and is protected from warping. With the help of vacuum air, the cooled part is purified from dust.
