MJF Nylon PA12 Parameters
MJF works by using a series of inkjet printheads to selectively apply flux and refiners to a bed of powdered material (usually nylon). Infrared energy is then used to fuse the material layer by layer. MJF is known for its high print speeds, making it suitable for rapid prototyping and production applications. The inkjet printhead in the MJF accurately deposits flux and detail agents, resulting in accurate and detailed prints. Nylon PA12 provides the parts with the required mechanical properties such as strength, toughness and flexibility. It is suitable for producing functional prototypes and end-use parts across a variety of industries, including automotive, aerospace, consumer goods, and more.
