The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 μm. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.

The disclosure relates to a methods and devices for producing three-dimensional objects by a beam acting on and selectively solidifying a construction material applied layer by layer. The devices include at least one process chamber, which has a building platform on which the three-dimensional object is created, a radiation source for producing the beam, at least one beam guiding element, and a process assisting device movable above the building platform and having a first and second module with a beam guiding portion arranged between for the beam that is directed onto the building platform. Each module has at least one application device for discharging construction material and a monitoring device with at least one sensor element for sensing the applied and solidified layer of construction material.
