Freeform Construction: Mega-scale Rapid Manufacturing for construction

Rapid Manufacturing with Fdm in Jig & Fixture Construction

The weight of a device is an ergonomic criterion as well. Devices that are carried and operated by people may not exceed a weight of 5 kg (11 lbs.). Previously, this was achieved by using lowdensity materials, such as aluminum or polyamide. An additional weight reduction, however, can be obtained through the use of ABS plastics and the FDM process. The density differences of ABS and polyamide d...

Efficient Voronoi diagram construction for planar freeform spiral curves

We present a real-time algorithm for computing the Voronoi diagram of planar freeform piecewise-spiral curves. The efficiency and robustness of our algorithm is based on a simple topological structure of Voronoi cells for spirals. Using a Möbius transformation, we provide an efficient search for maximal disks. The correct topology of Voronoi diagram is computed by sampling maximal disks systema...
