Abstract
An apparatus and a method are provided for manufacturing three-dimensional objects by selective solidification of a build material applied in layers. A heating element having at least two functional openings is used to improve the manufacturing process and in particular to optimize heat input. One of the at least two functional openings serves as a material passthrough and another of the at least two functional openings simultaneously serves as a radiation passthrough. An additional heating and/or cooling device serves to control the temperature of build material applied through the material passthrough.
