EOSINT P 800

The first laser-sintering system world-wide processing high performance polymers.   

These elevated process temperatures enable the creation of parts with extremely good performance. The process characteristics known from traditional laser-sintering are comparable, but the material used, the temperatures required and the resulting product characteristics are completely different.  

High-performance polymers are very interesting due to their excellent material properties for a number of applications and industries. However until now they could not be used in the laser-sintering process due to their melting point between 220°C (428°F) and 380°C (716°F) degrees. Due to its capability for process temperatures up to 385°C (725°F) the new EOSINT P 800 is the world's first system which enables the laser-sintering production process for this highly interesting group of materials. It builds on the proven and mature design of the EOSINT P 730. Through a number of completely redesigned components such as the processing chamber and a removable frame it has now been advanced to the level of requirement necessary for a high-temperature processes.

Establishing a temperature level that is around 200°C (392°F) higher than with ordinary laser-sintering applications presents new challenges regarding long-term stability, managing thermal expansion and temperature distribution within the system. As a consequence EOS applies new materials that haven’t previously been used in laser-sintering system design. The patented deployment of glass ceramics for the removable frame serves as a good example here. As such, the design not only fulfils the process requirements of temperature distribution but also the mechanical accuracy requirements, taking into account as well the thermal expansion.  

The modular setup of the new components prepares the system for future improvement innovations to be added through upgrades. Highly efficient insulation means that the energy consumption of the EOSINT P 800 is only slightly increased compared to the EOSINT P 730, although the process operates at a much higher temperature level than conventional polymer laser-sintering processes. The process control of this newest layer building process differs significantly from the traditional process. For example heating-up and cooling-down is performed in a parameterised manner due to the higher level of temperature to be bridged. The system contains an optional OnlineLaser-PowerControl (OLPC) which measures in real-time the actual laser output-power and optionally does also a closed loop control of the laser power.
