Title: IMPROVED CARTRIDGE FOR FEEDING A STEREOLITHOGRAPHY MACHINE AND STEREOLITHOGRAPHY MACHINE EMPLOYING SAID CARTRIDGE
Abstract:
The invention is a cartridge (1, 100) for stereolithography machines (200), which comprises a supporting structure (3) provided with connection means (10) suited to removably connect it to the stereolithography machine (200), a first reservoir (5) suited to contain a material (M1, M2) and provided with a first duct (8) and with a delivery mouth (81) which are suited to place it in communication with a container (4), a feeding unit (7) suited to feed the material (M1, M2) from the first reservoir (5) to the container (4), shutter means (9) suited to close the delivery mouth (81) of the first duct (8), and a second reservoir (12) suited to contain the material (M1, M2). The cartridge (1, 100) furthermore comprises a second duct (13) interposed between the first reservoir (5) and the second reservoir (12) in such a way as to place them in communication with each other. The feeding unit (7) is configured so that it conveys the material (M1, M2) from the first reservoir (5) to the second reservoir (12) and vice versa through the second duct (13) when the shutter means (9) are in the position in which they close the delivery mouth (81).
