3D printing is used in various areas: in addition to inexpensive and fast prototypes, more complex functional components are also manufactured for low loads. Another area of application is the manufacture of components for trade fair construction, currently the complete hull model of the sailboat for a demonstrator of the boat to show the sailing behavior of the finished boat.

PET-G material with high dimensional stability optimal for hull model

For this project, the German RepRap X1000 3D printer was used primarily with the PET-G material, as this is much more stable against slow thermal deformation than other materials. The PET-G impresses with its high breaking strength and dimensional stability at a temperature up to about 80 ° C. The material can be processed just as easily as PLA and also has an extremely high surface quality, which, when used appropriately, makes reworking of the objects unnecessary. The material also adheres very well to the standard PET film and is characterized by the fact that there is almost no warping or warping. The PET-G is classified as flame retardant according to fire protection regulation B1, which is important for the use of the electrical system in the case of the sailing team. PLA filament was also used for the gearbox and various smaller installation parts.

WDS Software & Service GmbH from Pulheim near Cologne, a verified partner of German RepRap, has made itself available for the project with the Sailing Team at TU Darmstadt.

In 2008 the project of the Sailing Team of the TU Darmstadt was launched, so that extensive experience in the field of autonomous navigation development has been gained within the past nine years. In the meantime the team has grown to 40 members.

As part of the World Robotics Sailing Championships 2013 in Brest, France, the first, 110 cm prototype of the sailing team sailed 7 km unmanned across the Atlantic. The boat sailed to predetermined GPS coordinates and mastered all the tasks for which a person usually has to be on board. Since 2015, work has been ongoing on a larger successor model, which will then cross the Atlantic. (yup)
