Abstract

Dispositif destiné à faire varier le volume de l’enceinte chauffée d’une imprimante 3D. Le volume de l’enceinte, dans laquelle est fabriquée la pièce par ajout successif de matière, augmente avec le nombre de couches fabriquées. Ainsi le volume chauffé afin de permettre ou d’optimiser la fabrication additive, est adapté aux différentes phases du processus de fabrication additive. Il est réduit lors des phases de préchauffe et de chauffe du plateau et de l’enceinte, ce qui permet un gain en énergie et en temps de chauffage. Il est au maximum fonction de la hauteur maximale de la pièce fabriquée. La variation du volume de l’enceinte chauffée est réalisée par l’utilisation d’une enceinte télescopique dimensionnée pour supporter les contraintes de hautes températures. L’enceinte télescopique se déploie par simple gravité et peut être soulevée pour retirer la pièce en fin de fabrication.Device intended to vary the volume of the heated enclosure of a 3D printer. The volume of the enclosure, in which the part is manufactured by successive addition of material, increases with the number of layers manufactured. Thus the volume heated in order to allow or optimize additive manufacturing, is adapted to the different phases of the additive manufacturing process. It is reduced during the preheating and heating phases of the plate and enclosure, which saves energy and heating time. It is at most a function of the maximum height of the manufactured part. The variation in the volume of the heated enclosure is achieved by the use of a telescopic enclosure sized to withstand the stresses of high temperatures. The telescopic enclosure unfolds by simple gravity and can be lifted to remove the part at the end of manufacturing.
