description	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. La présente divulgation concerne un procédé d'impression 3D d'un objet imprimé en 3D. Le procédé comprend l'impression d'une couche d'une composition de matériau de construction comprenant une solution d'un sel métallique et d'un support liquide. Un réseau métallique interconnecté est formé par réduction du sel métallique dans la composition de matériau de construction imprimé. Une couche supplémentaire de la composition de matériau de construction est imprimée sur le réseau métallique interconnecté, et le sel métallique dans la couche supplémentaire est réduit pour former un réseau métallique interconnecté supplémentaire au-dessus du réseau métallique interconnecté sous-jacent pour fournir une structure poreuse à l'objet imprimé en 3D. En superposant et en joignant des réseaux métalliques interconnectés les uns au-dessus des autres, des régions poreuses peuvent être construites à l'intérieur de la partie imprimée en 3D.
