3D printing with PEEK

High Performance: chemical resistant, wear resistant and heat resistant.

PEEK is the abbreviation for polyetheretherketone, a high-temperature-resistant polymer. The material is semi-crystalline and thermoplastic and can be machined very well in the melting process from temperatures of over 372 °C. 3D printing with PEEK using laser sintering is also possible. In the case of FKM, PEEK is therefore in powder form and is specially processed in the EOSINT P 800 high-temperature system. The laser-sintered objects and workpieces achieve tensile strengths of up to 90 MPa and a modulus of elasticity of 4400 MPa. Objects made of PEEK HP3 can be used permanently at temperatures of up to 180 °C mechanically-dynamically, up to 240 °C mechanically-statically and up to 260 °C electrically. This makes PEEK predestined for use in aerospace and motor sports. Due to its biocompatibility, 3D printing with PEEK is also suitable for medical technology and prosthetics.

Possible applications for PEEK HP3

The material’s high-temperature and wear resistance as well as its chemical resistance and biocompatibility make 3D printing with PEEK HP3 interesting for the medical, aerospace and motorsport industries. In medicine in particular, parts made of PEEK can replace stainless-steel and titanium, making it easier to produce prostheses, for example. The material’s fire resistance is an additional criterion that benefits the aerospace industry. Lightness and high heat resistance are of very great importance, which is why PEEK is increasingly replacing metal components here.
