# PEEK (Poly-ether Ether Ketone)
- Mechanical properties massively beyond other plastics
- Close to steel
- Twice as tough as the toughest polycarbonate
- Used in missiles and is fireproof

# PEKK (Polyether Ketone Ketone)
Same building blocks as PEEK, in different levels
- Worse than PEEK mechanically, still far beyond other filaments
- Much easier to print compared to PEEK
