This paper presents the development process of a new porous titanium panel made by Spark Plasma Sintering (SPS) for laminar flow control by suction. First, the development process of the porous panel is detailed. Small samples are produced by partial sintering in SPS. Then, they are characterised in permeability and surface roughness. Based on these data, the sample with the most interesting characteristics is chosen to be upscaled and make a full suction panel of $300\times275$\si{\milli\meter}. Afterwards, this new SPS panel is mounted on an academic flat plate model equipped with suction chambers to delay the boundary layer transition by applying wall suction. It is ensured there is a bidimensional with zero pressure gradient grazing flow in a low disturbance wind tunnel, leading to a modal boundary-layer transition scenario. Then, the transition position is determined using hot-wire anemometry for three configurations: a smooth reference case, a case with the SPS panel without suction and a case with the SPS panel and wall suction. These results are then compared with a previous study led in the same flow conditions with microperforated titanium sheets as porous panel.
