Non-transitory computer-readable medium comprising executable instructions for use in computer devices and industrial robots used in material processing of a two- dimensional sheet like material

A non-transitory computer-readable medium comprising executable instructions for use in material processing of a two-dimensional sheet like material using a computer device, wherein the instructions, when executed by one or more processors of the computer device, cause the computer device to:

• obtain information related to a desired design of a three-dimensional object;
• obtain information related to material characteristics of the two-dimensional sheet like material;
• define a primary surface and a secondary surface of the desired design of the three-dimensional object;
• and
• define a geometrical relationship between said primary surface and secondary surface;
• wherein
• the secondary surface is a reflection of the primary surface in a two-dimensional plane, and wherein
• when said primary surface is concave said secondary surface is convex, or when said primary surface is convex said secondary surface is concave;
• and
• provide, or otherwise create, a digital instruction for a fully developed spreading and subsequent folding of a two-dimensional sheet into the obtained desired design of the three-dimensional object, wherein said digital instruction is based on the defined primary and secondary surfaces, respectively, and said obtained material characteristics.
