This is a semi crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. The only disadvantage with PEEK is the high price, which limits its application to high value items.
The processing conditions used to mould PEEK can influence the crystallinity, and therefore the mechanical properties. It’s mechanical properties at high temperatures have led to it being used in at least two varieties of Reprap extruder as thermal insulation. This means the main mechanical structure of the extruder can be made of the same material that is being extruded, provided that the PEEK insulator prevents heat from travelling beyond the intended melt zone.
