Methods, systems, and apparatus, including medium-encoded computer program products, for designing three dimensional lattice structures include, in one aspect, a method including: obtaining a lattice within a 3D lattice design space for a 3D model being created with a 3D modeling program; identifying junctions in the lattice that are potential sources of particle traps at an interface between the 3D lattice design space and a surface present in the 3D model; and removing the potential sources of particle traps by modifying cell space defined between the identified junctions and the surface. In addition, the surface can be a surface of a solid region defined in the 3D model, and the method can include: identifying beams in the lattice having junctions lying on the surface; and extending each of the identified beams by a length amount to cause overlap between the identified beams and the solid region.

Lattice structure interfacing

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.

Three-dimensional design and manufacturing systems

A collaborative method of generating a design representation of an object between a first user and a second user is described. The method comprises: designating, at a first user terminal, a set of design object variables relating to different aspects of the design representation; specifying, at the first user terminal, constraints for the set of design object variables, the constraints comprising a range of first user designated values for each of the designated object variables of the set; receiving at a second user terminal, the set of design object variables, the constraints for the set and the design representation via a communication network; enabling, at the second user terminal, manipulation of the design object representation, the enabling step comprising enabling selection of a particular value of at least one of the designated object variables only within the constrained value range specified by the first user; and presenting on the second user terminal a graphical representation of the design object representation as specified by the second user selection.
