Description

This model shows the structure of dengue virus, which causes dengue fever.

Dengue virus is a mosquito-borne virus that causes dengue fever in humans. This virus has an RNA genome surrounded by a capsid, or protein shell, with icosahedral (20-sided) symmetry. The capsid is made up of glycoproteins arranged in geometric patterns with two-, three-, and five-fold symmetry.

The 3D model can be viewed and rotated in the online 3D Viewer. The accompanying downloads provide other ways to display and interact with the model. The “3D Preview” contains an image of the model that can be viewed and rotated within Adobe Acrobat. The “3D Movie Loop” is a short looping animation that shows the model being rotated. The “3D Printing Data” STL file allows the model to be printed on a 3D printer.

Note that the STL file can be viewed with the free MakerWare software from MakerBot, but MakerWare will print only to a MakerBot printer. Please use the software provided with your 3D printer to print the STL file.
