What is MJF 3D Printing?

Multi-Jet Fusion (MJF) is a type of 3D printing technology that uses a combination of heat and pressure to produce parts from powder-based materials. MJF works by depositing a layer of fine powder material on a build platform and then fusing it together using a thermal print head. The process is repeated layer by layer until the entire part is built.

MJF is known for its ability to produce high-quality parts with consistent, water-tight, properties, making it a good choice for a wide range of applications, including functional prototypes, end-use parts, and low-volume production runs. The technology can produce parts with high accuracy, good surface finish, and excellent mechanical properties. It’s also capable of producing parts with complex geometries and internal structures, which can be difficult to produce with other 3D printing technologies.

MJF is typically used with engineering-grade materials, such as PA 12 (nylon), which offer high strength and stiffness, good wear resistance, low moisture absorption and excellent chemical resistance to oils, greases, hydrocarbons, and alkalis.

Why using MJF over SLS?

Speed and Efficiency -MJF surpasses SLS with multiple print heads, perfect for intricate projects on tight schedules.
Sustainable Printing - MJF and SLS recycle powder, but MJF's higher reuse ratio boosts sustainability and cost-efficiency over SLS.
Smoother Surface Finish - Choose MJF for a superior, smoother surface finish, surpassing SLS print quality.
Consistent Part Quality - MJF ensures consistent quality and precise dimensions, surpassing SLS variations.
Expansive Material Selection - MJF offers versatile materials, like low-moisture & robust PA 12 (nylon), surpassing SLS.
Cost-Effective - MJF materials are often more affordable than SLS, ensuring cost-effectiveness for specific applications.
