1. A method comprising 3D printing a 3D item, the method comprising
depositing during a printing stage 3D printable material and an optical fiber, to provide the 3D item with the optical fiber at least partly embedded in 3D printed material,
wherein the 3D printable material during at least part of the printing stage comprises a light transmissive material, the method further comprising providing during the printing stage a light escape part comprising 3D printed material comprising the light transmissive material, where visible light propagating through the optical fiber can escape from the optical fiber via the 3D printed material comprised by the light escape part to external of the 3D item, and
wherein during the printing stage the light escape part is further provided by providing an outcoupling feature to the optical fiber for facilitating light escape from the optical fiber via the outcoupling feature.
