A binder component for a feedstock compound for use in a shaping and sintering process comprises b-i) 3 to 70% by volume of at least one first thermoplastic and/or wax-type material, and b-ii) 30 to 97% by volume of at least one second thermoplastic and/or wax-type material, based on the total volume of the binder component b). The first thermoplastic and/or wax-type material and the second thermoplastic and/or wax-type material differ in at least one property which property is selected from (1) solubility in a solvent, (2) degradability induced by heat and/or a reactant, and (3) volatility. The first thermoplastic and/or wax-type material is less soluble, less degradable or less volatile than the second thermoplastic and/or wax-type material. Tcross is higher by not more than 60 K than TP, wherein TP is the DSC melt peak temperature of the binder component b), and Tcross is the temperature at the intersection between the storage modulus G? curve and the loss modulus G? curve in a dynamic viscoelasticity measurement of the binder component b). The feedstock compound containing the binder component and non-organic sinterable particles is used in an additive manufacturing process, an injection molding process, a pressing process or a casting process.
