Zusammenfassung:	The present disclosure relates to the field of liquid handling and dispensing systems in combination with additive manufacturing. In particular, it relates to temperature-controlled units, i.e. dispensing heads and source well holders, for receiving, holding and releasing liquid and semi-liquid material, liquid-handling and dispensing systems, apparatuses and methods for applying temperature- sensitive liquids.A temperature-controlled unit (1)comprises at least one Peltier element (3), each Peltier element having opposite first and second surfaces (4a, 4b). The unit (1) further comprises at least one cooling element (5). The at least one Peltier element (3) is arranged to have each respective first surface (4a) facing a reservoir block (2) of the unit (1). The at least one cooling element (5) is thermally connected to the Peltier element (3) and arranged to transfer heat generated by the at least one Peltier element (3) and dissipate the transferred heat away from the at least one Peltier element (3). La présente invention relève du domaine des systèmes de manipulation et de distribution de liquide en combinaison avec la fabrication additive. En particulier, l'invention concerne des unités à température régulée, c'est-à-dire des têtes de distribution et des supports de puits source, destinées à recevoir, à contenir et à libérer un matériau liquide et semi-liquide, des systèmes de manipulation et de distribution de liquide, des appareils et des procédés destinés à appliquer des liquides sensibles à la température. Une unité à température régulée (1) comprend au moins un élément Peltier (3), chaque élément Peltier ayant des première et seconde surfaces opposées (4a, 4b). L'unité (1) comprend en outre au moins un élément de refroidissement (5). Le ou les éléments Peltier (3) sont agencés pour avoir chaque première surface respective (4a) faisant face à un bloc réservoir (2) de l'unité (1). Le ou les éléments de refroidissement (5) sont reliés thermiquement à l'élément Peltier (3) et agencés pour transférer la chaleur générée par le ou les éléments Peltier (3) et dissiper la chaleur transférée à distance du ou des éléments Peltier (3).
