Design Tips for Multi Jet Fusion 3D Printing
Multi Jet Fusion (MJF) is an additive manufacturing, or 3D printing, process that builds parts layer-by-layer with infrared heating alongside fusing and detailing agents to create 3D models in powdered material.
The Multi Jet Fusion process begins with a layer of material applied to the build platform area. In the opposite direction, in one continuous pass, the machine applies droplets of fusing and detailing agents across the full working area. This pass combines the printing with the fusing energy. The process continues until all of the layers have been built. After the print is finished, the build unit with the material and parts are rolled to a processing station for cooling and powder excavation. Leftover powder is recycled with new material for use in future builds.
This layer by layer manufacturing process allows for the direct fabrication of complex parts that would be cost-prohibitive, if not impossible, to produce through traditional manufacturing processes. For example, interior features, undercuts and negative draft are not an issue for Multi Jet Fusion.
Multi Jet Fusion offers expanded possibilities for 3D printed production parts. Create complex geometries in durable nylon faster and more cost-effectively than ever before. Parts made from Multi Jet Fusion have:
- Improved mechanical properties due to greater process and operation controls
- Higher isotropic characteristics from the technology's enhanced build method
- Faster turn-arounds from build speeds that are five times faster than the other 3D printing technologies
As with any manufacturing process, a number of issues can impact the performance of a particular design. In many ways, designing parts for Multi Jet Fusion is very similar to designing parts for Laser Sintering (LS), with a few key differences.
