The present disclosure relates to a method of 3D printing a 3D printed object. The 5 method comprises printing a layer of a build material composition comprising a solution of a metal salt and a liquid carrier. An interconnected metal network is formed by reducing the metal salt in the printed build material composition. A further layer of the build material composition is printed over the interconnected metal network, and the metal salt in the further layer is reduced to form a further 10 interconnected metal network over the underlying interconnected metal network to provide a porous structure to the 3D printed object. By layering and joining interconnected metal networks one on top of another, porous regions may be constructed within the 3D printed part.
A method of 3D printing a 3D printed object, said method comprising
The method as claimed in claim 10, wherein the presence of oxygen causes at least some of the metal in the interconnected metal network to oxidise as or after the metal salt is reduced.
The method as claimed in claim 11, which further comprises thermally treating the interconnected metal network to reduce any metal oxide to metal.
A build material composition comprising a metal salt;
