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.

Apparatus with a module for the layered manufacture of a product

A three-dimensional printing system for manufacturing a three-dimensional article includes a chassis, a door, and a plurality of latches. The chassis defines an internal process chamber and a vertical opening for accessing the internal process chamber. A peripheral seal surrounds the vertical opening. The plurality of latches are arranged around the peripheral seal. The latches individually include a hook. The vertical door is mounted to the chassis by a linkage. The door includes a plurality of laterally extending pins individually corresponding to the latches. The pins have locations along the door to be individually engaged by the latches when the door is positioned in the closed position. The latches are individually configured to rotate the hooks around a second lateral axis (Y) when the door is positioned in the closed position with the door closing over the opening to secure the door with respect to a first lateral axis (X).

Three-dimensional printing system with improved process chamber

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.
