  The spherical proportional counter is a gaseous detector used in a variety of
applications, including direct dark matter and neutrino-less double beta decay
searches. The ACHINOS multianode structure is a read-out technology that
overcomes the limitations of single-anode read-out structures for large-size
detectors and operation under high pressure. A resistive ACHINOS is presented,
where the 3D printed central component is coated in a Diamond-Like Carbon (DLC)
layer. The production and testing of the structure, in terms of stability and
resolution, is described. Further applications in fundamental physics and
industry are also discussed.
