Abstract: Particles each having a sinterable core and a polymeric coating on at least a part of the core, wherein the polymeric coating includes a polymer that can be removed via decomposition by heat, catalytically or by solvent treatment, and wherein the polymeric coating is present in an amount of 0.10 to 3.00% by weight, relative to the total weight of the particles, as well as the use of these particles in an additive manufacturing process such as a powder bed and inkjet head 3D printing process. The particles and the process are able to provide a green part having improved strength and are thus suitable for the production of delicate structures which require a high green strength in order to minimize the risk of structural damage during green part handling.
