Item Fast and Simple Printing of Graded Auxetic Structures(University of Texas at Austin, 2019) Carton, M.A.; Ganter, M.One of the great promises of additive manufacturing is the ability to build parts with volumetrically graded parameters that would be difficult or impossible with traditional manufacturing. This paper presents a method of procedural generation and unsupported fabrication of 2D objects patterned with functionally graded auxetic (negative Poisson’s ratio) cellular structures using commercially available FDM printers. Several types of two-dimensional auxetic pattern are fabricated. The resulting printed objects exhibit a graded response to load, deforming corresponding to local patterning. Deformation is studied using imaging of loaded structures and applications in several areas are considered.
