Abstract

Apparatus for creating scaled three-dimensional physical models of characteristics of microscopic objects, includes a transducer apparatus including a transducer for creating first electrical signals representative of the magnitude of a physical characteristic of the microscopic object at a selected point within a selected area thereof, the first electrical signals having a first component defining said selected point and a second component related to the magnitude of the physical characteristic, a material shaping apparatus configured to create a physical model in a workspace, the workspace having an area related to the selected area of the microscopic object by a first selected scale factor, the material shaping apparatus including apparatus responsive to second electrical signals representing x, y, and z co-ordinates in the workspace for directing the formation of the physical model; and control apparatus, connected to the transducer apparatus and the material shaping apparatus, for converting the first electrical signals from the transducer to the second electrical signals and supplying the electrical signals to the material shaping apparatus, the control apparatus processing the first electrical signals according to the first and second selected scale factors.
