PEEK Filament
Polyether Ether Ketone
C
Niche or outclassed
Also known as:Polyether Ether KetonePEEK (superpolymer)
Family:PEEK-familyWhy Use PEEK?
- Exceptional mechanical/thermal/chemical resistance; self-extinguishing; near metal alternative
- Extreme heat resistance, chemical resistance, and strength
Things to Consider
- Extremely expensive and very difficult to print; warping/curling issues (pricing varies widely by brand, so verify current pricing)
Safety & Ventilation
- Print PEEK in a well ventilated area. Higher-temperature materials like this can release fumes and fine particles while printing. An enclosure improves print quality and helps contain fumes, but it is not a substitute for fresh air, so vent the enclosure or run an air filter and avoid an unventilated occupied room.
Frequently Asked Questions
What is PEEK filament?
