Abstract: In a method for producing a three-dimensional workpiece (12), a first raw material powder (50) is applied to a substrate (18) in order to produce a raw material powder layer consisting of the first raw material powder (50). The raw material powder layer consisting of the first raw material powder (50) is selectively irradiated with electromagnetic radiation or particle radiation in order to produce a solidified first workpiece layer portion (52) from the first raw material powder (50). Non-solidified first raw material powder (50) is then removed from the substrate (18). In the next step, a second raw material powder (54) is applied to the substrate (18), in order to produce a raw material powder layer portion consisting of the second raw material powder (54) adjacent to the first workpiece layer portion (52), The raw material powder layer portion is selectively irradiated with electromagnetic radiation or particle radiation in order to produce a solidified second workpiece layer portion (56) from the second raw material powder (54) adjacent to the first workpiece layer portion (52). The non-solidified second raw material powder (54) is heated in order to produce a continuous porous sintered layer portion (58) from the second raw material powder (54) adjacent to the first workpiece layer portion (52) and the second workpiece layer portion (56).
