The EOS P 770 is a Laser Sintering System with two lasers for the production of large parts and for industrial high-throughput manufacturing. The system has the largest building volume available on the market. Thanks to its new hardware and software features, the EOS P 770 is up to 20 percent more productive than its predecessor. 

With 10 commercial polymer materials and 18 combinations of materials/layer thicknesses currently available for the EOS P 770, EOS is a benchmark in terms of material variety.


  • Optimized temperature management, improved recoating speed and high-power lasers reduces the build time and cost per part significantly
  • Well-established EOSAME feature homogenizes the energy input, thus ensuring excellent mechanical part properties and dimensional accuracy within the overall build volume*


  • Improved digital scanners for considerably higher laser accuracy. As a result the overlap area has no visible edges
  • Integrated CoolDown Station provides optimal cool down conditions which lead to the best properties in the final part – in particular with regard to dimensional accuracy and colour stability.
  • Continuous and accurate temperature control enabled by the spot pyrometer


  • 10 commercial polymer materials and 18 combinations of materials/layer thicknesses are available
  • EOS ParameterEditor allows definition of customized exposure parameters based on proven starting values

* the specified build volume depends on the material; for PA 2200 it is 700 x 380 x 580 mm (27.6 x 15 x 22.9 in)
