Benefits of technology

The present inventors have created a modeling material that can absorb high amounts of water and has high impact resistance and thermal resistance. This material can be used in 3D printing to create objects with improved performance.

Problems solved by technology

Yet, a trade-off exists between HDT and toughness, since materials that exhibit high HDT typically exhibit low impact resistance, and materials exhibiting high impact resistance typically exhibit low HDT.

Abstract

Formulations and methods employing these formulation for fabricating an object by additive manufacturing, such as three-dimensional inkjet printing are provided. The formulations comprise at least 50 weight percents of hydrophilic curable materials, and upon curing, provide a material that is characterized by water absorbance of at least 5%, and by high HDT and impact resistance values. Objects containing cured material made of these formulations are also provided.

Description

RELATED APPLICATION[0001]This application claims the benefit of priority from U.S. Application No. 61 / 937,773, filed on Feb. 10, 2014, the contents of which are hereby incorporated by reference as if fully set forth herein.FIELD AND BACKGROUND OF THE INVENTION[0002]The present invention, in some embodiments thereof, relates to Additive Manufacturing (AM) of an object, and, more particularly, but not exclusively, to a composition and method for additive manufacturing of an object which exhibits desirable mechanical properties.[0003]Additive manufacturing is generally a process in which a three-dimensional (3D) object is manufactured utilizing a computer model of the objects. Such a process is used in various fields, such as design related fields for purposes of visualization, demonstration and mechanical prototyping, as well as for rapid manufacturing (RM).[0004]The basic operation of any AM system consists of slicing a three-dimensional computer model into thin cross sections, trans...
