A method for manufacturing a shaped body, comprising creating a mixture of a metal powder and binding agent, compacting the mixture to form a green compact, heating the green compact to a debinding start temperature T, debinding the green compact by controlled heating of the green compact from start temperature Tto end temperature Tat a heat-up rate R, presintering the debindered green compact to the presinter end temperature Tat a heat-up rate R, cooling the green compact from the presinter end temperature Tat a cool-down rate R, whereby at least the heat-up rate R, the presinter end temperature T, and the cool-down rate Rare tuned relative to each other in such a way that the presintered green compact forming a blank has a surface porosity of 16% to 22% after presintering, and machining and sintering of the blank to form the shaped body.
