1. A material unit for an additive manufacturing device (AM) having a resin vat and a reservoir, wherein the resin vat comprises a base which is transparent at least in sections, wherein the resin vat is connected to a holder for the reservoir, and wherein the holder is configured such that resin (R) emerging from an outlet of the reservoir held by said holder can flow into the resin vat, wherein the holder comprises an actuating device for actuating a valve of the reservoir accommodated therein, wherein the actuating device actuates the valve for a pivoting movement over a limit angle (β), wherein the limit angle (β) corresponds to a substantially perpendicular arrangement of the holder and/or the reservoir with respect to the resin vat.
