Before training your dragon, print a 3D tail for him

3D printing (or additive manufacturing, AM) describes any of the various processes used to make a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. While its limitless potential in manufacturing, the construction industry, transportation and human health has been widely recognized, 3D printing also plays a significant role in animal protection and conservation.

Several cases of using 3D printing for animal assistance have been reported during the past few years. Although artificial limbs have been used to help poor dogs and other animals who lost their legs, 3D printing makes the design and manufacture of the limbs far easier. And, thanks to the well developed 3D-scanning technology, the printed limbs are more efficient and comfortable for animals. Just see how happy this dog is.

Birds also benefit from 3D printing. This bald eagle and Costa Rican toucan both received printed beaks which will hopefully improve their chances of survival. And a tortoise has even been given a new shell thanks to 3D printing technology.

3D printing can be also applied to animal conservation in the wild. For example, the Wildlife Conservation UAV Challenge uses 3D printed drones to save endangered animals from poachers. 3D printing has also been used to build animal habitats including hives for bees, artificial reefs for fish, and nests for birds.

For the sake of scientific education, 3D printed models of skulls, organs and muscles can be used for demonstrations and detailed observations. In research, the technology can play an important role in studies of animal behavior and physical ecology. For example, 3D printed birds and fish can be used to explore how animals adapt to hydraulic resistance.

The wide-ranging potential for using 3D printing in animal protection and conservation seems limitless!

Could the ‘drone’ be a new technology to survey African wildlife?

journal.pone.0054700.g001

Nazinga Game Ranch is a protected area in southern Burkina Faso, dominated by clear shrub and woody savannah and home to one of the most important elephant populations of the Western Africa.

Researchers from the University of Gembloux Agrobiotech in Belgium tested one of the first unmanned aerial surveys to study the wildlife of Nazinga. They achieved this study using ‘drone’ technology i.e. a small Unmanned Aircraft System (UAS) (pictured). This technology was shown to have the potential to be a valuable alternative to current walk and light aircraft survey techniques.

The Belgian researchers tested different aspects of this new technology on the wildlife and more particularly on elephants. Firstly they wanted to know if the animals reacted when the UAS passed over and found no animal flight or warning reactions were recorded when the plane passed over at a height of 100 meters. Secondly they flew the UAS at different heights (from 100 meters to 700 meters) and showed that only elephants are visible at these heights (while the medium and small sized mammals are not). The pictures taken at a height of 100 meters do however allow easy observation of the elephants.

In the light of this information one elephant survey has been completed in Nazinga Game Ranch so far. This UAS aerial survey has revealed several advantages in comparison to the traditional plane based surveying: (1) an easier flight implementation as a very short airfield is needed, (2) low safety risks as there is no pilot on board, (3) higher reliability in rough weather conditions, and (4) a lower global cost. However, to be able to cover hundred kilometres at a time it is important to improve the flight time of the small UAS as for the moment it is quite low.

Technological improvement of some aspects of the drone will make it more efficient and in the future could compete the light aircraft to monitor the wildlife in Africa.
