The device object of this article allows having a fine control of the thermal conditions inside the print
chamber of a 3D Plastics/Metals machine. It provides high density of thermal exchange to the
entering airstream (that has a big impact on the cooling rate of the print bed or the solvent removal
rate) but at the same averts the explosion risk through increasing the thermal exchange surface
using a heatsink element in order to reduce the necessary difference of temperature between the
airstream and the heating element. It also provides a complete differentiation of the inner and outer
volumes of the printer in this area through the use of different sealing elements.
