Embodiment Construction

[0068] The present invention, in some embodiments thereof, relates to additive manufacturing (AM) of objects, and more particularly, but not exclusively, to a system and method for AM of objects utilizing a combination of materials and / or scan patterns.

[0069] Before explaining at least one embodiment of the present invention in detail, it should be understood that the present invention is not necessarily limited in application to the components and / or components and / or Details of the structure and arrangement of the method. The invention is capable of other embodiments or of being practiced or carried out in various ways.

[0070] The method and system of the embodiments of the present invention manufacture a three-dimensional object in a step-by-step manner by forming multiple layers in a configuration pattern corresponding to the shape of the object.

[0071] As used herein, the term "object" refers to an entire object or a portion thereof.

[0072] Each layer is formed...

Abstract

A method of additive manufacturing of a three-dimensional object is disclosed. The method comprises sequentially forming a plurality of layers each patterned according to the shape of a cross section of the object. In some embodiments, the formation of at least one of the layers comprises performing a raster scan to dispense at least a first building material composition, and a vector scan to dispense at least a second building material composition. The vector scan is optionally along a path selected to form at least one structure selected from the group consisting of (i) an elongated structure, (ii) a boundary structure at least partially surrounding an area filled with the first building material, and (iii) an inter-layer connecting structure.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 61 / 476275, filed April 17, 2011, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention, in some of its embodiments, relates to additive manufacturing (AM) of objects, and more particularly, but not exclusively, to a system and method for AM of objects utilizing a combination of materials and / or scan patterns. Background technique [0004] In general, additive manufacturing is a process in which a computer model of an object is utilized to manufacture a three-dimensional (3D) object. Such processes are used in various fields such as design-related fields for visualization, demonstration and mechanical prototyping purposes as well as for rapid manufacturing (RM). [0005] The basic operation of any AM system involves slicing a 3D computer model into thin sections, converting the results into 2D p...
