A 3D printing system build material supply unit includes a tray with an opening that defines a spreading plane in which a recoater spreads build material. A double vane is rotatably mounted inside the tray with the rotation axis extending along the tray below the spreading plane and with each vane having convex front and rear sides. A controller controls rotation of the double vane such as to supply a dose of build material with the front side of one vane to the spreading plane by rotating the double vane into a trimming position in which the front side of the one vane approaches the spreading plane such that the dose of build material is enclosed between the front side of the vane and the spreading plane. Excess build material to be trimmed by the recoater accumulates on the other vane rear side and is lowered into the tray.
