Ultrafuse® PA

First BASF Filament Development Based on Ultramid®

The key features of Ultrafuse PA are the high strength and high modulus. Furthermore, Ultrafuse PA shows a good thermal distortion stability.

Buy the material


Ultrafuse® PA is the translation of BASF ́s Ultramid® to the 3D printing space. It is based on a copolyamide 6/66 grade of intermediate viscosity. With Ultrafuse® PA, it is possible to print semi-flexible thin parts; however, it is very rigid at higher thicknesses. It has a lower melting temperature than PA6 and PA66, meaning it can be printed at a lower temperature and also has better impact resistance versus PA6 and PA66, opening up a whole new application field for end-users.
