Overview of the MJF Technology
The Multi Jet Fusion (MJF) 3D printing process is a state-of-the art powder-based printing technology. The MJF process
produces high-quality, functional parts and is ideal for manufacturing prototypes and end use products.
Multiple inkjet arrays pass over a build plate, depositing a fusing agent and a detailing agent onto each 80 µm layer of powder. High heat then melts the powder where the fusing agent is applied, allowing for parts with complex geometries with fine details to be manufactured. The MJF platform provides a build space of 380 × 284 × 380 mm, where unfused powder supports other parts as they are printed, eliminating the need for any support material. The printer can manufacture multiple parts at once, making it an efficient process for volume production. The final parts are strong, durable, and biocompatible for skin contact, making this technology a great option for the prosthetics and orthotics field.

Material Properties
PA 12 (Polyamide 12)
PA 12 is a robust thermoplastic that can produce high-density, strong and complex parts. It can withstand high levels of stress and strain making it a good choice for producing parts that need to withstand heavy loads, impacts, or wear and tear. It provides excellent chemical resistance and it’s biocompatibility certifications meet USP Class I-VI and US FDA guidance for skin surface devices.
