  • Apparatus for 3D printing of bottom-up photo-curing type, with independent elastic membrane system and tilting reference and relative methods of use
    Patent number: 11673327
    Abstract: The present invention concerns an apparatus for 3D printing of bottom-up photo-curing type, comprising a light source (26) above which a tank (10) containing a photo-curing liquid material (24) is placed inside which it is immersed an extraction plate (25), which is equipped with moving means with alternating rectilinear motion, along a direction perpendicular to the bottom of said tank (10) from a position at a distance from the bottom of said tank (10) equal to the thickness of a layer obtainable by photo-curing of said photo-curing liquid material (24), the bottom (14) of said tank (10) being constituted by an elastic membrane (23) transparent to the radiation of said light source (26), said tank (10) being positioned in correspondence with a hole (13) of a support plate (12), said hole being provided with a rigid support (11), transparent to the radiation of said light source (26), wherein said rigid support (11) is provided with means for displacing with respect to said hole (13), from a position in whic
