Design features of additively-manufactured multi-hole probes

The multi-hole probes are popular tools of velocity measurement, appreciated if the flow direction changes in a wide range. The universality of application areas implies a variety of design parameters of the probe - a configuration, length, tip shape, pressure taps diameter etc. Number of possible configurations increases especially if modern manufacturing methods are utilized, so some technological limitations are eliminated or at least reduced. The paper gives an overview of the quality of additively manufactured probes in different conditions, to eventually assess the impact of crucial design parameters of the probe on its performance.
