Abstract
Methods for additive manufacturing include depositing a printing material in suspension within a printing tray containing a stressed medium, to form a three-dimensional object. This deposition of printing material is performed via at least one step of injecting the printing material using a nozzle of a printing head, which nozzle is immersed in the stressed medium and is able to move within the stressed medium in the three dimensions in space. This method comprises at least a step of modifying the level of the stressed medium in the printing tray. Additive manufacturing devices includes a stressed medium disposed in a printing tray, a printing head designed to dispense a printing material, and a device for modifying the level of the stressed medium of the printing tray. The printing head has a nozzle displaceable within the stressed medium in three spatial dimensions.
