Internal structure of the lungs, 3D printed plastic

Internal architecture of the trachea and lungs, 3D printed in Frosted Ultra Detail plastic. This image shows the internal structure of the lungs. The trachea (windpipe) divides into two branches called bronchi, which each divide further to produce smaller branches called bronchioles. After a number of further subdivisions, the bronchioles terminate into alveoli, which are the air sacs of the lungs where gas exchange occurs. An extension of a previous project, the lungs belong to Caroline who was diagnosed with Hodgkin lymphoma cancer. The 2D data contained in her CT scans were converted into 3D renders by the artist who was then able to export them to a printable format. The size of the original artwork is 15cm (h) x 10cm (d) x 15.6cm (w). Wellcome Trust photography by Ben Gilbert.
