Designers using ArcGIS for example can export VRML files which contain colour information. So any of the information in the software model can be exported and 3D printed as a physical colour model. This should present opportunities for engineers working in all of the fields where ArcGIS is used and where communication to a wider audience is required.

geometry can be 3D printed.
Last time I received a file exported from ArcGIS the exporter was not working properly and required some manual editing to complete the work. Which leads me on to the second reason why 3D printing is underused in many sectors and that is that software vendors have not built coherent export features to enable 3D printing from their software. Too often it is a plugin or an extension that needs to be bought or downloaded. What is needed here is vision and leadership within software companies to get the most out of their software.
A great many of the mature design products like MicroStation and ArcGIS have VRML export capabilities, not to enable colour 3D printing, but because 15 - 20 years ago developers thought that VRML would enable them to create dynamic 3D models on the web. However this does mean that many kinds of 3D software are able to export colour 3D models that with a bit of work can be made in to physical 3D models.
Exporting VRML from ARCGIS requires ArcGIS for Desktop with 3D Analyst extension.
