Abstract

In a method of providing a material amount for a generative manufacturing method, a three-dimensional object (2) is formed by selectively solidifying layers of a material at locations corresponding to the cross-section of the object (2) in the respective layers. The quality of the manufactured objects is reproducibly recorded, thus, improving the method. At least one first material amount of a powder is provided, which is characterized by at least one feature. Data is detected, which relates to the at least one feature of the first material. Then, the data is stored, which relates to the at least one feature of the first material. Thus, the method can provide an identifiable powder amount used in manufacturing each layer of the object.
