Multi Jet Fusion is a powerful industrial 3D printing process that enables the rapid production of highly accurate durable parts, offering many advantages over processes such as selective laser sintering. Multi-jet fused parts are ideal for end-use applications, small and medium series production, rapid prototyping or as a link in injection molding.
MJF technology uses two separate thermal inkjet arrays to create full-color 3D objects. When printing, one of them moves from side to side, ejecting material, causing one to move up and down, spraying, coloring and depositing to give the finished product the desired strength and texture. The two arrays then change direction to maximize coverage and productivity. A refiner is then sprayed onto the already formed structure. After that, the outside heats up the parts that have been and are being deposited. These steps are repeated until the entire object is printed in layers.
How does multi jet fusion work ?
The multi jet fusion process begins by coating the working area with a layer of material. In the opposite direction, the machine prints fuses and refiners across the entire work area in one continuous scan. This pass combines the printing and fixing energy, and the whole process is complete. This innovative multi jet fusion 3d printing technology allows rapid printing along the width of the bed, allowing for extremely high precision and dimensional accuracy.
Multi Jet Fusion Design Guidelines
Our multi-jet fusion includes design guidelines that focus on improving part manufacturability, enhancing appearance, and reducing overall production time.
Vapor Smoothing -AMT's chemical vapor polishing technology
The principle of Vapor Smoothing is not complicated. After contact with solvent vapor, the surface of the MJF printed part will dissolve, and the micro-convex part of the surface will dissolve preferentially, and the dissolution rate is higher than that of the concave part. The surface of the dissolved liquid is affected by tension and tends to shrink as much as possible. The raised part will flow downward to the concave part, and a uniform and smooth surface will be produced after solidification.
Dyed a standard black color
Sand blasting removes all powder and leaves a consistent overall texture. Then the parts are dyed standard black.

Advantages of MJF 3D Printing Process
1. The MJF process can simplify workflows and reduce costs, enabling rapid prototyping to achieve groundbreaking economic parts manufacturing.
2. An open materials and software innovation platform that lowers barriers to use and supports new applications across industries.
3. MJF 3D printing can produce end-use parts with near-isotropic characteristics on demand, and the performance of the products is better. Manual finishing is rarely required. This makes it ideal for mass production of functional parts.
4.The printing speed for small batch orders is fast and the comprehensive cost is competitive.
