EOSINT P 770

EOS P 770 – 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.

Overview

Efficency

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*

Flexibility

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

Quality

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 color stability.
Continuous and accurate temperature control enabled by the spot pyrometer
