The selective production of exotic species (SPES) project aims to construct at Legnaro National Laboratories (LNL) a new facility for the production of radioactive ion beams (RIBs) according to the isotope separation on-line (ISOL) technique. In the specific case of the SPES facility, a uranium carbide Target is impinged by a $40 {MeV}$, $200 \mu A$ proton beam produced by a cyclotron proton driver. Under these conditions, a fission rate of approximately $10^{13}$ fissions per second is expected in the Target. Radioactive isotopes produced in this way are then ionized, extracted at low energy and post-accelerated through the existing ALPI accelerator complex. In this context, both the Target and the Ion Source play a crucial role in the definition of the radioactive ion beams, deeply affecting intensity and purity. In this contribution the SPES Target-Ion Source unit is presented and described in detail, with a specific focus on the last developments introduced by Additive Manufacturing technologies.
