Abstract
Plastic powder for use as building material for additively manufacturing a three-dimensional object by selectively solidifying the building material at the positions corresponding to the cross-section of the three-dimensional object in the respective layer, in particular by exposure to radiation, wherein the plastic powder comprises a mixture of polymer-based particles and particles of a particulate additive and wherein the particulate additive is selected such that the crystallization point of the mixture of the polymer-based particles and the particulate additive is substantially not increased compared to the crystallization point of a mixture of the polymer-based particles without the particulate additive.
