Abstract

A device (1) for manufacturing a three-dimensional object by a layer wise solidification of a building material at positions in the respective layers that correspond to the object is provided. A feed (96) that supplies the building material to a building space (10) in the device (1) and at least two filler portions (98a, 98b) that are provided at the feed (96) and are independent from one another are provided, wherein one connector (99a, 99b) is provided for each building material supply container (100a, 100b) in order to supply the building material from outside of the device (1).
