PEEK (Polyether ether ketone) is an exceptionally strong, biocompatible, chemically
resistant thermoplastic. This makes it ideal it ideal for use in biological implants, as well
as many other applications. PEEK implants are currently produced through CNC,
injection molding, and SLS due to the material's high melting point (343C). These
processes are expensive due to PEEK's high material cost. 3D printing using PEEK will
vastly decrease cost while allowing personalization of each implant to each patient.
Additive manufacturing using high performance polymers like PEEK and ULTEM has
enormous potential in multiple industries. Lighter aircraft parts made from high
performance polymers will mean lower fuel consumption and emissions – two pressing
challenges in commercial aviation. In ground transportation, on demand production of
spare parts will reduce down time and inventory costs.
Additive manufacturing with PEEK presents substantial challenges. PEEK's high melting
point, tendency to shrink, and semi-crystalline nature demand rigorous thermal control.
The presentation discusses these challenges and PEEK’s enormous potential in additive
