Abstract
An arrangement for additive manufacturing by selective fusion of layers of a three-dimensional product from a powder bed including successively formed powder layers is provided. The arrangement includes a heating element having a powder layer facing surface, arranged in a powder layer heating position above a powder layer, in such a way that heat radiation emitted from said heating element heats at least a part of the powder layer before the selective fusion of a layer of the three-dimensional product from the powder layer.
