So here are the details.

* the kinect is connected to a linux system using libfreenect

* the opensource Kinect Fusion (KinFu) implementation by pcl is used -> pointclouds.org/news/kinectfusion-open-source.html

* the hard part: PCLs KinFu runs with CUDA supported by a Nvidia Tesla C2050 (not a usual household graphicscard)

* the pointcloud postprocessing is done with meshlab, have a look on one of the many howtos you will find regarding meshlab and solid modeling eg. -> edutechwiki.unige.ch/en/Meshlab_for_RapMan_tutorial

* for alignment and scaling i use NetFabb because its easy to handel dimensions and position -> netfabb.com/

* finally the stl is printed on a shapercube with ABS plastics shapercube.com/start/index

The example is about 10cm high, and can stand for its own. Atm the foodprint is very small so it is tricky to print. I'll send updates when the 175mm tall print is done .)
