The invention relates to a method for coating particles of a plastic, metal and/or ceramic powder material for producing an adhesive-containing coating material, in particular for producing appropriate particles by compressing a 3D binder. Said coating is applied to fluidized particles in a gaseous phase by means of a coating solution, at least the particles and/or coated particles being exposed to ionized particles. A method for producing bodies or sintered bodies from organic liquid binders by compressing the 3D binder and the use thereof are also disclosed.
