In order to have ensure a proper dosing of a 3D printing system, it is disclosed a feeding mechanism for feeding build material to a surface that comprises: a receptacle to receive build material; and an outlet of the build material having a substantially quadrilateral opening with a first dimension and a second dimension orthogonal to one another; the outlet further comprising a third dimension orthogonal to the first dimension and the second dimension defining the height of the outlet, and the feeding mechanism being to selectively feed build material from the receptacle through the outlet onto a surface as the feeding mechanism moves along a travel direction over the surface, being such travel direction parallel to the first dimension of the outlet, the feeding mechanism further comprising an actuator to modify the magnitude of at least one of the second dimension or the third dimension outlet.

Feeding mechanisms for 3D printers

The appliance includes a housing and a stationary internal cup for receiving an unprocessed cosmetics portion. Inner and annular pistons with seals between the two pistons and between the annular piston and the stationary cup are moved sequentially up and down to mix the cosmetic portion to a processed skin formulation, the skin formulation being presented to the user when mixing is complete and the lid removed.
