Zusammenfassung:	The metering type feeding mechanism for 3D printing comprises a sand storage box, a pressing plate is movably arranged in the sand storage box, first connecting plates are fixedly connected to the two sides of the upper surface of the pressing plate, limiting boxes are arranged on the two sides of the sand storage box, and second connecting plates are connected into inner cavities of the limiting boxes in a sliding and penetrating mode; connecting pipes are fixedly connected to the tops of the two sides of the sand storage box, first through holes are formed in the tops of the second connecting plates, and second through holes are formed in the tops of the two sides of the sand storage box. By means of the arrangement mode that the pressing plate is matched with the second connecting plate, the first connecting plate is driven by the pressing plate to move downwards together, the pressing plate moves to the bottom of the inner cavity of the sand storage box, and the second connecting plate does not have the b
