Systems and methods for controlling the transfusion pressure in an additive manufacturing system are described. The system has a layer transfusion assembly that can include a build platform. The layer transfusion assembly is configured to transfuse the layers at a transfusion pressure in a layer-by-layer manner onto the build platform to print a three-dimensional part, and a controller is configured to set the transfusion pressure, wherein the transfusion pressure can vary along the x-direction of the build platform in a controlled manner. Des systèmes et des procédés de régulation de la pression de transfusion dans un système de fabrication additive sont décrits. Le système comprend un ensemble de transfusion de couche qui peut comprendre une plateforme de construction. L'ensemble de transfusion de couche est configuré pour transférer les couches à une pression de transfusion d'une manière couche par couche sur la plateforme de construction pour imprimer une partie tridimensionnelle, et un dispositif de commande est configuré pour régler la pression de transfusion, la pression de transfusion pouvant varier le long de la direction x de la plateforme de construction de manière contrôlée.
