With the new Laser Pro Fusion technology, EOS is introducing a new development aimed to maximize productivity. To this end, the interaction between powder material and laser was optimized. In contrast to previous laser-sintering methods, however, it is not one CO₂ laser that runs along the entire construction area, but up to one million diode lasers are used. These lasers can achieve a maximum total output of up to 5 kW.

For each component layer, only the lasers at the points where the CAD data of the component specifies the points for melting the powder are activated to the exact pixel. The new technology significantly shortens the exposure time, regardless of the number of components and their geometries.
