Peek is part of the family of polyaryletherketone super polymers. They are polymers that, processed with FDM technology, can have different microstructures: amorphous as well as product and semi-crystalline if subjected to a subsequent heat treatment. The amorphous is characterized by greater ductility and resistance to impacts, while the semi-crystalline for resistance to temperatures, chemicals and greater mechanical properties. It can be added with short carbon fibre to emphasize its thermal properties that reach really high values and to make the components more rigid.
