How HP Multi Jet Fusion Works

Multi Jet Fusion (MJF) is a revolutionary HP additive technology that heat fuses parts at the voxel (volumetric-pixel) level and uses thermal inkjet arrays to quickly print complex and intricate parts. It’s essentially a powder bed technology that uses your CAD file to print layer by layer, adding fusing and detailing agents and high-intensity light to fuse the material wherever the ink is deposited. MJF parts can be produced with a variety of materials, including polymers and springy, durable elastomers.

Here’s how our MJF solutions can help you:

  • Create layers of highly accurate parts with intricate details and aesthetics, in a single piece or sub-components.
  • Simplify design and manufacturing processes to reduce processing time and costs while ensuring precision.
  • Produce rubber-like parts with advanced materials like the new production-ready elastomeric, Thermoplastic Polyamide (TPA).
  • Build parts that perform well in cold and warm environments with multiple color and surface finishing options.
  • Get the superior isotropic properties and exceptional mechanical performance you need from HP MJF parts.
