EOS P 770

Manufacturer: EOS
Type: Additive Manufacturing, Plastics

High Productive Laser Sintering System for Parts of up to One Meter in Length

Improved part quality with a build volume of over 150 liters

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 re-coating speed, and high-power lasers reduce 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 cooldown conditions which lead to the best properties in the final part – in particular with regard to dimensional accuracy and color 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 the definition of customized exposure parameters based on proven starting values.
