Abstract: Cover assemblies for machines are disclosed, as well as machines and methods for producing three-dimensional components by selectively solidifying a material by a beam acting on the material, including a build cylinder cover that sealingly closes an opening of the build cylinder for changing of the build cylinder, and including a process chamber cover associated with the build cylinder cover, which are detachably connected to one another via an interface, wherein the build cylinder cover and the process chamber cover are formed as a single handling unit for changing the build cylinder.

Abstract: 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.
