Polyether Ether Ketone (PEEK) is a high-performance, colorless polymer thermoplastic. It is semi-crystalline, is resistant to many chemicals, and has excellent mechanical properties. PEEK is used in medical implants, aerospace, and motorsports. PEEK melts around 662º F.
Polyether Ether Ketone (PEEK) in 3D Printing
PEEK has been used to 3D print violins by the University of Exeter’s Centre for Additive Layer Manufacturing (CALM). Selective Laser Sintering (SLS) is used to create PEEK parts.
How Polyether Ether Ketone (PEEK) Works
A layer of PEEK powder is deposited onto the print bed and a laser fuses the powder together. A fresh layer of powder is deposited and fused. Unsintered powder surrounds the part as support material. The process of layering the powder and fusing it with a laser is repeated until the part is complete. The part is then removed from the powder and cleaned.
