Zusammenfassung:	The present invention relates to an improved feedstock for a 3D manufacturing process, in particular a Fused Filament Fabrication process. The feedstock comprises (P) sinterable particles made of a metal, metal alloy, glass, ceramic material, or a mixture thereof; and (B)a binder composition comprising (b1) 5-15 % by weight, relative to the total weight of the binder composition, of a polymeric compatibilizer, and (b2) 85-95 % by weight, relative to the total weight of the binder composition, of a polymeric binder component, the polymeric binder component being selected from the group consisting of (b2-1) a polymer mixture or polymer alloy, the mixture or alloy comprising at least a first and a second polymer, the Tg of the first polymer being -20 DEGC or lower and the Tg of the second polymer being 60 DEGC or higher; (b2-2) one, two or more block copolymers, comprising at least a first polymer block and second polymer block, the first polymer block having a Tg in the range of -20 DEGCor lower and the second
