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.

Methods for the additive manufacture of components in layers, and corresponding computer program products

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.

Cover arrangements for machines for manufacturing three-dimensional components

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for switching between different operating modes on a processing machine. The operating modes are different from one another in respect of operator intervention requirements of an operator of the processing machine, One of the methods includes switching from a first operating mode to a second operating mode, looking up stored operating settings specific to the second operating mode and related to one or more potential operator interventions, changing operation of the processing machine in accordance of the stored operating settings specific to the second operating mode, and providing feedback to the operator of the machine, indicating whether a switch to the second operating mode is complete or whether at least one of the potential operator interventions is required.
