What is MJF 3D Printing?
MJF 3D printing, or Multi Jet Fusion, is an industrial additive manufacturing technology developed by HP that uses a powder bed fusion process to build parts layer by layer. It’s known for producing strong, detailed, and functional plastic parts with excellent speed and surface quality.
The process works by spreading a thin layer of nylon powder across the build platform. Then, an array of inkjet nozzles selectively applies fusing and detailing agents to define the part. A heat source then passes over the layer, causing the treated areas to fuse. This is repeated layer by layer until the object is fully formed.
MJF is commonly used for:
- Automotive and aerospace components.
- Medical devices and custom orthotics.
- Functional prototypes and end-use parts.
- Consumer products and housings.
