Abstract
A method of additive manufacturing of a three-dimensional object is disclosed. The method comprises: extruding from a tip of an extruder contours of a modeling material to form on a supporting platform a plurality of layers corresponding to slice data of the object; and establishing a vertical relative movement between the tip and the supporting platform while the material is extruded.

A method of additive manufacturing of a three-dimensional object, the method comprising:
- extruding from a tip of an extruder contours of a modeling material to form on a supporting platform a plurality of layers corresponding to slice data of the object;
- and
- establishing a vertical relative movement between said tip and said supporting platform while said material is extruded.

A system for additive manufacturing of a three-dimensional object, the system comprising:
- a supporting platform;
- a modeling material extruder;
- a drive for establishing relative motion between said modeling material extruder and said supporting platform;
- and
- a controller operatively associated with a computer and being configured to receive slide data of the object from said computer and to control said drive and said extruder to extrude contours of a modeling material thereby to form on said supporting platform a plurality of layers corresponding to said slice data, wherein a vertical relative movement between said tip and said supporting platform is established while said material is extruded.

A method of processing a data file for extrusion additive manufacturing, data file having slice data including three-dimensional contour coordinates, the method comprising:
- identifying closed planar contours in the data;
- for each of at least some of said closed contours, updating vertical coordinates of at least a segment of said contour, such that, following said update, said segment is tilted at an angle relative to a plane engaged by said contour prior to said update, thereby processing said data file;
- and
- storing said processed data file in a medium readable by a controller of an extrusion additive manufacturing system.
