Abstract: The invention relates to a system for the layered manufacture of a three-dimensional product starting from a powder, in particular a metal powder. More specifically, the invention relates to a system in which selective laser melting is applied to manufacture a product. Here, successive powder layers are covered by an energy beam, such as a laser beam, in order to melt the powder in this layer in whole or in part and subsequently to solidify or sinter it and to create successive layers of the product in this way.

Abstract: An apparatus for layered manufacture of a three-dimensional product includes a build chamber having a window, a build platform within the build chamber, a calibration device that is physically separated from the build chamber, an optical system including a beam source and a scanning apparatus, and a mobile base. The mobile base is configured to position the scanning apparatus at two spaced part positions including a (1) production position and a (2) calibration position. At the production position the scanning apparatus is configured to receive an energy beam from the beam source and to reflect and scan the energy beam through the window and to a build surface over the build platform to create a layer of the three-dimensional product. At the calibration position the scanning apparatus is configured to reflect the energy beam to the calibration device but not through the window.

Abstract: The invention relates to an apparatus for layered manufacture of a three-dimensional product, in particular for application of an additive manufacturing technique such as selective laser melting. This apparatus has a build chamber in which said product is constructed and an optical system that extends outside of the build chamber. The optical system has at least a beam source to generate an energy beam and contains corresponding scanning means to move this beam. Here, a control unit is provided that controls the scanning means to move the beam so that it strikes a selected position. The wall of the build chamber features a closed window that is transparent for the beam so that it passes through the window and enters the build chamber.

Abstract: A device is provided for cleaning and/or replacement of a laser window of a process chamber, enclosed by an outer wall, containing a modified atmosphere, in particular a process chamber for layered printing of a 3D object by a technique such as Selective Laser Sintering (SLS), where this device features an opening in the outer wall that is fitted with the laser window and where this laser window allows a laser beam from a laser source located outside of the process chamber into the process chamber, where an external sealing ring is provided that extends between the outer wall and this laser window.A method is also provided for cleaning and/or replacement of the laser window in the opening of the outer wall of the enclosed process chamber.

Abstract: A three dimensional printing system includes a build module, a powder storage module, a powder transport conduit, a vertical powder transport module, and a powder layering apparatus. The build module has a lateral side. The powder storage module is located at least partially below the build module. The powder storage module has a lateral side and defines an internal volume for holding powder. The powder transport conduit transports the powder to a lateral location that is laterally offset from the lateral side of the powder storage module. The vertical powder transport module is laterally offset from the lateral sides of the build module and the powder storage module and includes a lower end for receiving powder from the lateral location and an upper end having a laterally extending powder outlet. The powder layering apparatus receives the powder from the laterally extending powder outlet.
