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

Abstract: A modelling head for a three-dimensional printing machine, comprising a base body having a work surface suitable for enabling the formation and adhesion of an object, a support device connected to said base body and a movement member for moving said base body, wherein the support device is adjustable so as to change the orientation of the base body and in particular of the work surface relative to the movement member and is configured to switch, in an automated manner, from an unlocked configuration, in which it allows a change in the orientation of the base body relative to the movement member, and a locked configuration in which it locks the configuration assumed by the base body relative to the movement member.
