EOS Features High Temperature System

EOS (Frankfurt / Krailling, Germany) introduced its EOSINT P 800 first high-temperature system for laser sintering of high-performance polymers at EuroMold 2008. Developed expressly for the new system is the material EOS PEEK HP3, which belongs to the polyaryletherketone family. The materials characteristics include flame retardance, lightweight, high tensile strength and biocompatibility, making them a good choice for industries such as aviation, medical devices or mechanical engineering.

High-performance polymers have not been used in the laser-sintering process due to their melting point between 220°C and 380°C degrees. The EOSINT P 800 has the ability to process temperatures up to 385°C so that it can use these polymers for the laser-sintering production process.

PEEK HP3 EOS is a high-performance polymer designed especially for laser-sintering. EOS converts the polymer into powder and processes it to be used in the production process. Laser-sintered products reach a tensile strength up to 95MPa and a Young's Modulus of 4,400MPa. These values said to be up to 100 percent higher than for the materials PA12 and PA11, which are very common on the market today. A number of redesigned components in the EOSINT P 800 such as the processing chamber and a removable frame make it possible for the system to manage high temperature processes.
