HP Multi Jet Fusion (MJF) is a powder bed fusion 3D printing process akin to Selective Laser Sintering (SLS). Rather than using a laser as the heat source like in SLS, MJF employs HP’s proprietary ink jet technology to fuse layers of powder. This advanced 3D printing technology selectively applies fusing and detailing agents to transfer and control thermal energy from infrared heat lamps. The build process is repeated for each layer of powder until the part is printed. Powder from each previous layer acts as the support, so there is no need for support structures to produce complex parts with lattice structures, overhangs and undercuts.
After the build cycle is completed, parts are moved to a processing station for cooling and the majority of loose powder is extracted using an integrated vacuum.
Parts are then bead blasted to remove any residual power. Post-processing techniques can then be employed to improve visual appearance and performance of MJF parts, such as chemical smoothing, engineered coatings, and inserts for assembly.
MJF produces resilient end-use parts and functional prototypes with outstanding resolution, surface finish, and edge definition. With speeds up to ten times faster than Selective Laser Sintering, HP Multi Jet Fusion 3D printing makes production-level manufacturing and customization possible without expensive tooling.
