Abstract
The present disclosure provides three-dimensional (3D) printing methods, apparatuses, systems and software that comprise rotating a partially formed 3D object during the formation of a requested 3D object. The requested 3D object may comprise a cavity, an intrusion, or a protrusion. The rotation may be along an axis other than a vertical axis.
Claims20
A method for printing a three-dimensional object comprising:
- (a) modifying a first model of a requested three-dimensional object to form (i) a second model of the requested three-dimensional object from which a segment is omitted, and (ii) a third model of the segment;
- (b) printing a modified three-dimensional object above a platform according to the second model, which printing comprises a first three-dimensional printing methodology;
- (c) rotating the modified three-dimensional object relative to the platform about an axis that is not perpendicular to the platform;
- and
- (d) printing the segment according to the third model by using a second three-dimensional printing methodology, which printing comprises attaching the segment to the modified three-dimensional object to form the requested three-dimensional object.
2 more elements
A system for forming a three-dimensional object comprising:
- a platform above which at least a section of the three-dimensional object is printed;
- a first processor configured to accommodate a first model of a requested three-dimensional object;
- a second processor configured to accommodate a second model of the requested three-dimensional object from which a segment is omitted;
- a third processor configured to accommodate a third model of the segment;
- and
- at least one controller that is operatively coupled to the platform, the first processor, the second processor, and the third processor, which at least one controller is programmed to direct performance of the following operations:
- operation (i) direct the second processor, the first processor, the third processor, or any combination thereof, to modify the first model of the requested three-dimensional object to form the second model and the third model, operation (ii) direct a first printing of the modified three-dimensional object above the platform according to the second model, which first printing comprises a first three-dimensional printing methodology, and operation (iii) direct a second printing the segment according to the third model, which second printing comprises a second three-dimensional printing methodology, which second printing comprises attaching the segment to the modified three-dimensional object that has been rotated relative to the platform, to form the requested three-dimensional object.
