Abstract: The invention relates to a device for mounting printing heads for depositing fluids on a printing surface. The invention more particularly relates to a printing head mounting for improving the deposition precision and properties for a plurality of fluids. In order to do so, the present invention provides a printing head mounting having a geometric revolution axis about which are provided at least two means for maintaining printing heads. To this end, the invention provides a printing head holder that comprises at least two means (4) for maintaining printing heads (6) as well as anchoring means (10) for an observation module (12), characterized in that it comprises a geometric revolution axis (1) about which are provided the means (4) for maintaining the printing heads (6).

Abstract: The disclosure relates to a method for making multi-material three-dimensional components providing a mechanical link between thin layers. To this end, the disclosure provides a method for making a multi-material three-dimensional component that includes at least first and second materials. The method includes making at least two superimposed printed layers along discrete space routes of a printing travel, the printed layers being made by the contactless deposition of localised impacts of printing droplets, and a homogenous printed layer includes at least the first material, with the second material being excluded, while at least one mixed printed layer includes the first material, and at least the second material.
