HP 3D High Reusability PA 12

HP Multi Jet Fusion (MJF)

Nylon 12 (Polyamide/PA 12) 

Ideal for producing strong, low-cost, quality parts in low to high volumes

HP 3D High Reusability PA 12 is a robust thermoplastic that produces high-density parts with balanced property profiles and strong structures. This material was designed for the production of functional parts across a variety of industries such as watertight applications without any additional post-processing.

Designed for Production

Produce strong, functional, and complex parts
at a low cost per part.

HP 3D High Reusability PA 12, also known as Nylon PA12, is a thermoplastic material that produces high-density parts with balanced property profiles and strong structures. HP 3D High Reusability PA 12 provides good chemical resistance to oils, greases, aliphatic hydrocarbons, and alkalies and is the optimal material for complex assemblies, housings, enclosures, and watertight applications. Due to the surplus powder reusability, you can minimize the waste, thus achieving a low cost per part.

Work with Proto3000’s ISO 9001:2015 quality certified manufacturing services to have parts made with HP Nylon 12.
