Abstract: The present disclosure relates to a method of manufacturing a 3D printed object. The method comprises selectively applying a fusing agent onto powder bed material; and exposing at least part of the powder bed material to radiation to fuse at least part of the powder bed material to form a layer of the 3D printed object. The fusing agent and/or a detailing agent is selectively applied to the powder bed material in a predetermined arrangement to form a porous region in the 3D printed object. The 3D printed object is then treated with a modifying agent, such that the modifying agent at least partially penetrates the porous region of the 3D printed object.
