one embodiment described herein is a sheet of material 200 formed into accurate and high value structures by implementing a plurality of elongated slots 202 that are obliquely placed along a fold line 204 which create one or more strips 206 consisting of a length w , a width s and an angle f to said fold line 204 . the strips 206 are put into a state of plastic deformation through torsion which is controlled via the combination of said length w , width s , and angle f elements to create accurate , unique , complex and high value products or forms . the embodiments described allow for a greater degree of freedom of sheet material types , a greater degree of sheet material thicknesses , while simplifying implementation . this and other embodiments are also enclosed .
