Sintratec supports construction of the first Swiss Supersonic Rocket
A Swiss student project is shooting for the stars: As part of the student association for space, the team of project EULER is building the first supersonic rocket of Switzerland. For their construction, the students also make use 3D printing technologies such as Selective Laser Sintering.

Reaching supersonic with project EULER
One specific goal of ARIS is to win the annual Spaceport America Cup (SPAC). Every year, this competition attracts several hundred student teams from all over the world to the desert of New Mexico where their rockets compete against one another in various categories. For 2020 the corresponding rocket project of ARIS is named EULER – after the Swiss mathematician and astronomer Leonhard Euler – and is under the technical lead of physics student Michael Kerschbaum. «The aim of the project is to develop ARIS’ first supersonic rocket and fly it to an altitude of almost 10,000 meters» Michael states. And even though the Cup could not be held this year due to the COVID-19 pandemic, Michael’s team of 35 motivated students is still committed to this endeavor.
More flexibility thanks to 3D printing
Sintratec sponsors laser-sintered components
In the case of ARIS, 3D printed parts are usually located inside of the rockets, where material requirements are comparatively low. Components on the outside of the rocket on the other hand need to be aerodynamically optimized, as they affect the drag, while being robust enough to withstand the extreme forces during lift-off. FDM printers quickly reach their limits in such applications, which is why Team EULER looked for sponsors in the field of selective laser sintering. As the only Swiss manufacturer of SLS 3D printers, Sintratec was quickly found to be the right partner to produce the required work pieces on the Sintratec S2 system free of charge. The parts sintered with durable PA12 nylon powder are so-called Launch Lugs. «This is a very crucial part for the rocket’s flight – if the launch lug does not hold in the first few moments, the rocket cannot lift off the launch rail safely,» emphasizes Michael Kerschbaum.
First supersonic – then Orbit?
“The Sintratec technology allows for a high degree of flexibility in manufacturing combined with low weight – both important advantages for the aerospace sector.”
