Utilizing a Microscribe 3d digitizer, many kinds of physical models can be accurately translated into three-dimensional data. Although models made of rigid materials between the sizes of 10 to 36 inches are optimal for most work, almost any kind of model can be used. Models made of air-dried clay, wax, and plaster have all given acceptable results.
Unless the model possesses highly intricate or irregular surface texture that needs to be precisely captured, manual contact digitizing is often the most cost effective method of digitizing available. This will be true whether the model is a small, rough maquette that needs to be refined, or a large, detailed sculpture that is to be replicated with CNC techniques.
