Zusammenfassung:	In some examples, a system determines, based on a representation of an object to be formed by an additive manufacturing machine, locations in a layer of build material where a liquid agent is to be applied. As part of an edge adjustment at a greater control than a control provided by a dispensing assembly for the liquid agent, the system controls a location of an edge of the layer of build material relative to a location of the edge of the layer of build material specified by the representation of the object, the controlling of the location of the edge comprising adding a pattern of dry voxels in digital data representing locations of the layer of build material where the liquid agent is to be applied. Dans certains exemples, l'invention concerne un système qui détermine, sur la base d'une représentation d'un objet à former par une machine de fabrication additive, des emplacements dans une couche de matériau de construction où un agent liquide doit être appliqué. Dans le cadre d'un ajustement de bord à une commande supérieure à une commande fournie par un ensemble de distribution pour l'agent liquide, le système commande un emplacement d'un bord de la couche de matériau de construction par rapport à un emplacement du bord de la couche de matériau de construction spécifié par la représentation de l'objet, la commande de l'emplacement du bord comprenant l'ajout d'un motif de voxels secs dans des données numériques représentant des emplacements de la couche de matériau de construction où l'agent liquide doit être appliqué.
