Abstract (en)

[origin: WO2016096417A1] The invention provides a method (1) for the additive manufacturing of a workpiece (2) from a raw material (14), comprising at least one metal, wherein a geometric model (10) of the workpiece (2) is produced and the model (10) is divided into a plurality of individual parts (12a-12f), wherein each individual part (12a-12f) is manufactured in stages from the raw material (14), in that in a manufacturing step (32), a respective amount (34) of the raw material (14) is locally fused to an already manufactured part (13b-13e) of the respective individual part (12a-12f) using localized application of heat, and solidified in the same place, and wherein the individual parts (12a-12f) are joined by a diffusion process using the application of pressure (20a, b) and the local application of heat at the contact surfaces (24a-d), and in this way the finished workpiece (2) is joined. The invention additionally provides a workpiece (2) manufactured from a raw material (14) by means of a method (1) of this type.
