Abstract Scope |
Printing 2D features (e.g., circuits, antennas, or images) onto non-developable surfaces requires that the 2D feature distorts to some degree. UV mapping typically segments the surface, flattens it, maps the feature onto the segments, then reconstructs the surface. Continuity of features across boundaries of the segments can be a challenge. An algorithm will be described that does not segment the surface, but instead uses minimization of distances in a plane versus distances along the curved surface to distort the 2D feature as little as possible. The algorithm for remapping the 2D coordinates to new 3D coordinates for printing onto the surface will be described. Wrapping of the printed features around a surface using a user-defined preferred axis will also be described. Triangulation of the STL surface can present challenges when printing depending on the printing technique. A method of smoothing the surface via local curvature estimation will be discussed. |
