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.

Abstract: A device is provided for layered manufacture of at least a three-dimensional product by an additive manufacturing technique based on a powder. The invention therefore relates to a device for the layered manufacturer of a product based on a powder, in particular a metal powder.This device is fitted with a build chamber with a vertically movable build platform on which said product is manufactured and contains a powder dispenser for application of the successive powder layers on the build platform in a horizontal build surface. The powder dispenser can be moved back and forth over the build surface along a horizontal dispensing direction in order to apply said powder layers.Moreover, the device contains a hopper that must contain said powder in order to supply powder to the powder dispenser. This hopper has a bottom with a dosing opening that lets out into the build chamber and that works in combination with a dosing valve. More specifically, the dosing valve enables a measured quantity of powder to flow out of the hopper.

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.
