The present invention is directed to an improved method for supporting an object made by means of stereo lithography or any other rapid prototype production method. The generation of the support begins by determining the region that requires support in each layer of the object and defines a number of support points in this region. In a next step, a support mesh is generated connected to the object using these support points. The present invention also discloses different techniques that reduce superfluous edges to further optimize the support mesh. Finally, a support is generated from this support mesh. The present invention may facilitate the generation of supports data by employing more automation and less user analysis.

In one embodiment of the present invention, a support structure generator creates support structures designed to buttress three-dimensional (3D) digital models during 3D printing. In operation, the support structure generator incrementally constructs a support graph that connects overhanging points included in the 3D model with support points on a horizontal ground plane or relatively flat surfaces in the 3D model. After generating the 3D model, the support structure generator translates the connections between the nodes into support posts sized to sufficiently support the connected surfaces with the minimum amount of support material. Advantageously, the support structure is noticeably sparser than conventional support structures that fill a given support region with a solid volume of support material. Consequently, the time necessary for 3D printers to fabricate the support structure of interconnected support posts is less than the time required for 3D printers to fabricate conventional support structures.

In a method for the flight control of a plurality of aircraft flying in formation with respect to one another, correction signals are generated for an autopilot system or a command display in order to allow one or more following aircraft within the formation to follow a lead aircraft in the formation in a predeterminable relative position.
