For the purpose of producing the shaped body with extremely low tolerances and to be able to machine it using wet and dry processes without any problems, the following processing steps are suggested: creating a mixture of a metal powder and a binding agent, compacting the mixture to form a green compact, heating the green compact from room temperature to a debinding start temperature T1 , debinding the green compact by controlled heating of the green compact from the debinding start temperature T to a debinding end temperature T2 at a heat-up rate R1 in a manner that prevents damage to the green compact, presintering the debindered green compact to the presinter end temperature Tvs at a heat-up rate RHvS, cooling the green compact from the presinter end temperature Tvs at a cooldown rate Rxvs, whereby at least the heat-up rate RHvs, the presinter end temperature Tvs, and the cool-down rate RKvS are tuned relative to each other in such a way that the presintered green compact forming a blank possesses a surface porosity of between 16% and 22 % after presintering, and finally material-removing machining of the blank and sintering the machined blank to final density to form the shaped body.
