Applications for HP MJF
Vapor Smoothing HP Multi Jet Parts
Vapor smoothing is a post-processing technique used to enhance the surface finish of parts created with HP Multi Jet Fusion (MJF). This process helps achieve a smoother, more polished appearance by using chemical vapors to interact with the surface of the printed parts. The vapor dissolves the outermost layer of the material, resulting in a glossy finish and reducing the appearance of layer lines.
Advantages of HP Multi Jet Fusion
- Speed: Faster production times, especially for medium-to-large volumes.
- High-Quality Parts: Excellent mechanical properties, surface finish, and resolution.
- Customization: Highly suitable for creating custom, one-off, or small batch parts.
- Material Variety: A diverse range of materials with different performance characteristics.
- No Supports: The use of powder as support material eliminates the need for post-print support removal.

Overview: What is HP Multi Jet Fusion?
HP Multi Jet Fusion (MJF) is an advanced 3D printing technology that utilizes inkjet printing combined with thermal energy to produce highly accurate, functional, and durable parts. Unlike traditional additive manufacturing methods like Fused Deposition Modeling (FDM) or Stereolithography (SLA), MJF uses a powder bed fusion process to selectively fuse powdered materials, primarily polymers, to create complex geometries and end-use parts.
Developed by HP (Hewlett-Packard), MJF is recognized for its speed, precision, and versatility, making it ideal for industries requiring rapid prototyping, low-to-medium volume production, and functional components.
Key Benefits of HP Multi Jet Fusion
- MJF produces parts faster than traditional 3D printing methods. The ability to print full layers in one pass enhances throughput, making it ideal for high-volume production and rapid prototyping.
- MJF offers high accuracy and the ability to print fine details, making it suitable for parts requiring tight tolerances and complex geometries.
- Unlike other 3D printing methods that focus mostly on prototypes, MJF produces durable, functional parts with excellent mechanical properties, including strength, flexibility, and heat resistance.
- MJF supports a wide range of materials, mainly nylon-based powders, such as PA12, PA11, and PA12+. It also supports reinforced materials (e.g., glass-filled nylon) and high-performance polymers for demanding applications.
