Abstract: A method for manufacturing a part layer-upon-layer using Additive Manufacturing technology, the method including: printing the part together with an elastomeric enclosure shaped thereto leaving a gap free of material therebetween, the elastomeric enclosure including at least one opening; heating the ensemble of the printed part and elastomeric enclosure or keeping an operating printing temperature; applying vacuum by the at least one opening of the elastomeric enclosure so that the elastomeric enclosure deflates thus exerting pressure to the printed part; and maintaining the printed part under vacuum and heat during a predefined time.

Abstract: An impression chamber (1) for a 3D printer (6) adapted to receive a high performance plastic filament (19) and including a print head (7) and a printing bed (8), wherein the impression chamber (1) includes a thermally insulated plate (2) and a polyimide film (3) attached to the plate (2) for delimiting a printing space (20). The plate (2) is dimensioned to have a surface (2a) equal or larger than the major surface of the piece (5) to be printed, and the film (3) is dimensioned to surround the printing bed (8). The plate (2) is provided with a first through-hole (15) for allowing the passage of at least part of the print head (7), so that the plate (2) is moved by the movement of the print head (7) and the film (3) is dragged by said movement providing a flexible impression chamber (1).
