Regardless of the area out of which we produce a digital 3D model, we can create the CAD file in such a way that it can eventually be converted into a physical object using so-called 'rapid prototyping' technology.

This is useful for those who may want to keep the option of generating a physical model open.

Clients may find the combined cost of procuring a Zmapping model and deriving a physical model from it less than the single expense of commissioning a conventional physical model done by a model maker.

Conversion to physical is done by exporting the digital model, in a specific file format, to a three dimensional printer. Three dimensional printers create physical objects of any geometric complexity by layering suitable materials. This is known as an 'additive' printing technique.

As a whole range of machines and materials are available, the final physical model can be produced in a number of ways. It can be hollow or massive, coloured or transparent and impregnated with a variety of materials, all ready for further painting and texturing.

Models can also be produced using subtractive 'milling' techniques.

Either of the two methods can be used to produce blocks that can be pieced together indefinitely to make an entire physical model of any size.

Having been derived using photogrammetric technology, the dimensions of these types of physical models will - although scaled down - be geographically accurate.
