Sochi 2014: The Paralympic athlete from Germany will compete on the skis unpacked on the 3D-printer

On Paralympic games in Sochi in 2014 German biathlonist Martin Fleyg will use the special sedentary skis designed under his personal requirements. Scientists from Institute of mechanics of materials of Fraungofer (IWM) have developed a method of optimisation of professional sedentary skis by means of the 3D-press.

 Still sedentary skis were the unique samples created by technical and gifted athletes or their assistants. Development of the sports equipment adapted for needs of athletes with physical restrictions still is in embryo.

 Biathlonist Martin Fleyg was engaged in these sports at the age of 9 years. In order that посостязаться with other athletes on the Sochi Paralympic games, 24-year Fleyg has represented itself as the volunteer for creation of an individual ski set.

 Scientists from Institute of mechanics of materials of Fraungofer, together with research and industrial partners, work over the project under the name "Snowstorm" ("Blizzard") aimed at creation of superficial, but stable design for specific needs of Fleyga.

 During competitions on biathlon, skis are exposed to every possible loadings. In addition to ability to slide on a cross-country terrain, skis should possess good resistance to torsionny loadings.

 The first three-dimensional biometric data of movements of the athlete have been used for definition of an optimum arrangement of the athlete when landing. Then, scientists of institute used various computer simulations for creation of superficial design of sedentary skis.

 «The purpose of the project is definition of ways of design of skis which can be adjusted to individual athletes, but thus will allow to reach the maximum economic efficiency of process», – professor Sherge explains.

 Scientists of Institute of Fraungofer used a method of laser agglomeration for creation of the first prototype from high-plastic polyamide 12 with the integrated sensors, allowing to measure loading levels in a usage time. Ski sticks are also equipped with sensors for measurement of the efforts enclosed during driving.

 The obtained data have laid down in a basis of the second prototype, having allowed researchers to add cavities in the places testing the maximum loadings. Addition of steel fillers in the specified cavities has allowed to increase durability of the corresponding sections.

 The new ski set has passed the first tests for endurance on routes in Notschrei Nordic Center in Schwarzwald and mountain camp in Livinyo, Italy.

 Partners in the project hope that winter Paralympic games will stimulate interest to sports among fans. «We will be glad, if Games present to people with limited possibilities new ideas and will increase their interest to sports at the expense of demonstration of possibilities of the correct application of technologies», – professor Sherge has told.
