A system comprising: a substrate (6); a fixture (34) for receiving the substrate (6); and four fasteners (60a-d). The substrate (6) has two axes (56, 58), and a build surface (14). The substrate (6) comprises four slots (54a-d) through the substrate (6) from the build surface (14) to an opposite surface. Lengths of first and second slots (54a, b) are aligned along a first axis (56). The first and second slots (54a, b) are at opposite sides of the build surface (14) to each other. Lengths of the third and fourth slots (54c, d) are aligned along the second axis (58). The third and fourth slots (54c, d) are at opposite sides of the build surface (14) to each other. The fasteners (60a-d) fit through respective slots (54a-d). The lengths of the slots (54a-d) are greater than diameters of portions of the fasteners (60a-d) that are positioned through the slots (54a-d). L'invention concerne un système comprenant : un substrat (6) ; un dispositif de fixation (34) permettant de recevoir le substrat (6) ; et quatre éléments de fixation (60a-d). Le substrat (6) comporte deux axes (56, 58), et une surface de construction (14). Le substrat (6) comprend quatre fentes (54a-d) à travers le substrat (6) de la surface de construction (14) jusqu'à une surface opposée. Les longueurs de la première et de la deuxième fente (54a, b) sont alignées le long d'un premier axe (56). La première et la deuxième fente (54a, b) se trouvent sur des côtés opposés de la surface de construction (14) l'une par rapport à l'autre. Les longueurs de la troisième et de la quatrième fente (54c, d) sont alignées le long du second axe (58). La troisième et la quatrième fente (54c, d) se trouvent sur des côtés opposés de la surface de construction (14) l'une par rapport à l'autre. Les éléments de fixation (60a-d) s'adaptent à travers des fentes (54a-d) respectives. Les longueurs des fentes (54a-d) sont supérieures aux diamètres de parties des éléments de fixation (60a-d) qui sont positionnés à travers les fentes (54a-d).
