Abstract: A computer-implemented method of generating one or more variable stiffness structures includes determining a thickness of a first portion of a variable stiffness structure; determining a pressure that is to be applied to a surface of the first portion; selecting a first predetermined value for a stiffness attribute based on the thickness of the first portion and the pressure; and generating a model of at least part of the variable stiffness structure that includes the first portion, wherein the first portion has the predetermined value for the stiffness attribute.

Abstract: Embodiments relate to printing a three-dimensional (3D) article from a 3D design file describing a 3D design. A computer processor receives the design file in an encrypted format. The design file includes a design file identifier and a 3D printer identifier identifying a 3D printer capable of printing a 3D article in accordance with the design file. The processor constructs an authentication request for authenticating use of the design file with the printer and transmits the authentication request to an authentication server. The processor receives a response from the authentication server enabling printing of the article from the design file on the printer. The processor uses a decryption key included in the response to decrypt the design file including 2D contour data. The processor sends the decrypted design file to the printer associated with the printer identifier. The printer prints the article in accordance with the decrypted contour data.
