Abstract
A laser 3D printer presents a tubular compartment; a lifting platform engaged in a sliding manner in the tubular compartment; a dispenser for feeding a given amount of powdered material onto the lifting platform; a distributor for distributing the powdered material over the lifting platform; and a laser printing head for sintering the powdered material laid on the lifting platform; the dispenser being defined by two pipes, which are coaxial, are mobile with respect to one another about a rotation axis, and have respective openings configured for facing each other radially so as to define an outlet for the powdered material from the dispenser itself.
Claims9
A laser 3D printer comprising a substantially vertical tubular compartment (8), which extends downwards starting from a plane (P);
- a lifting platform (12) engaged in a sliding manner in the tubular compartment (8);
- a feeding unit (19) mounted above the plane (P) for feeding a powdered material (3) onto the lifting platform (12);
- and a laser printing head (4) for sintering the powdered material (3) laid on the lifting platform (12);
- the feeding unit (19) comprising a dispenser (23) for feeding a given amount of powdered material (3) onto the lifting platform (12) and a distributor (30) for distributing the powdered material (3) over the lifting platform (12) itself;
- and being characterized in that the dispenser (23) comprises an inner pipe (24) and an outer pipe (27), which are coaxial, are mobile with respect to one another about a rotation axis (25), and have respective openings (26, 29) configured for radially facing one another following upon their relative motion about the rotation axis (25) so as to define an outlet for the powdered material (3) from the dispenser (23).
