Australian researchers are using 3D printing to create a new generation of fish tags made of titanium
The aim is to use the tags to track big fish such as marlin, tuna, swordfish, trevally and sharks for longer periods.
CSIRO is printing the tags at its 3D printing facility, Lab 22, in Melbourne. The tags are printed overnight and then shipped to Tasmania where marine scientists are trialing them.
Tags are made of titanium for several reasons: the metal is strong, resists the salty corrosiveness of the marine environment, and is biocompatible (non-toxic to living tissues).
