HP® 3D HR PA 12 FR, enabled by Evonik

HP® 3D High Reusability PA 12 FR is a flame-retardant polyamide 12 designed for Multi Jet Fusion (MJF) 3D printing. It combines the mechanical durability, chemical resistance, and process reliability of standard HP PA 12 with enhanced fire-retardant properties, making it suitable for parts that must meet safety regulations in automotive, electronics, and industrial applications. This material is ideal for functional prototypes, housings, and enclosures where compliance with flammability standards is required, without compromising the excellent dimensional stability and reusability typical of HP’s High Reusability PA 12 family.
