Feedstock for an additive manufacturing method, additive manufacturing method using the same, and article obtained therefrom

A feedstock comprising:

• sinterable particles P made of a metal, metal alloy, glass, ceramic material, or a mixture thereof;
• and
• a binder composition B comprising:
• 5-15% by weight, relative to the total weight of the binder composition, of a polymeric compatibilizer b1;
• and
• 85-95% by weight, relative to the total weight of the binder composition, of a polymeric binder component b2,
• the polymeric binder component b2 being selected from the group consisting of:
• a polymer mixture or polymer alloy b2-1, the mixture or alloy comprising at least a first and a second polymer, the Tg of the first polymer being −20° C. or lower and the Tg of the second polymer being 60° C. or higher;
• at least one block copolymer b2-2, comprising at least a first polymer block and second polymer block, the first polymer block having a Tg in the range of −20° C. or lower and the second polymer block having a Tg of 60° C. or higher;
• and
• mixtures b2-3 of b2-1 and b2-2,
• wherein the amount of sinterable particles P is 40 Vol.-% or more of the feedstock.
