lightweight, fluid design... and of course music !
Laurent Bernadac is an INSA Toulouse engineer, and a virtuoso musician as well (Medal at the Conservatoire de Toulouse, Jazz Guitar & Violin Section). Laurent had a challenge: design an electric violin which wouldn't weigh more than a classic, wooden acoustic one. After several trials, he found the solution: a 3D Printed Violin. He named his concept 3Dvarius.
The promise is now a success:
Let's come back on this success story with an interview with Laurent Bernadac.
-"Not every musician designs his own instrument. Tell us about yourself and what motivates you."
-"I’m 28 years old, I live in Toulouse and I’m a mechanical and energy engineer, as well as a professional violinist. I play the electric violin, and I was seeking a unique way to play it that differed from the classical violin, which I play as well. I wanted to take the electric violin in a new direction. I love to discover and invent new things, and I’ve always tried to improve details that bothered me in every violin I’ve tried, to add more lightness. I try to reproduce the feeling of a classical violin on an electric violin, which has a more powerful, pure sound. This violin was really a personal project, driven by passion, to create an instrument that reflects who I am. I spent three years designing it, because I wasn’t in a hurry and didn’t have any orders to fill, since the violin was for me. My training as an engineer at INSA Toulouse was obviously helpful."
-"What are your sources of inspiration?"
-"I’m inspired by all of my experiences, and when I am able to produce through precision and effort, by analyzing what works and what doesn’t. Aerospace and space technology were a major inspiration, in particular for the design aspects. The violin is quite sleek – I wanted it to be as inconspicuous as possible, so that it almost disappears behind the musician. Light, yet with a strong identity. That’s why it’s clear and has a few curved shapes similar to aerodynamic designs. In aerospace, we try to achieve solidity and strength, as well as reliability and lightness. I sought to do the same with my violin – the instrument had to have the least amount of material possible, with all the requisite characteristics in terms of strength."
-"How did the creation process unfold?"
-"I used all sorts of digital resources. I did a lot of drawings, a lot of testing, and a lot of research on mechanics and sound waves. My school and former professors helped me a great deal and opened a lot of doors for me. I had originally wanted to make an aluminum violin, but the machining process used at that time unfortunately wasn’t able to produce the design I was looking for. I was also looking for transparency and aluminum was not suitable. In the end, I opted for polycarbonate. The 3D printing technique used is stereolithography, which offers precision as fine as ten microns. This technology uses a UV laser to polymerize photosensitive liquid resin. And I of course designed it on your amazing software: CATIA !"
An alternative to the drifts of the programmed obsolescence. L’increvable is the idea of changing the way we design and consume products. Let’s take the example of a product you can find in quite every house: the washing machine. A washing machine average cost is 350€. It decreased across time, but the repair cost of the washing machine increased by 125% the last 20 years.
Each musician aims to cultivate his art in order to be unique. Its aesthetic sound constitutes its identity.Is the answer to customize an instrument for each artist ? Can an instrument’s design influence its sound identity ?And can we industrialize custom-made instruments to make them accessible to every musician?
Our daily usage of connected objects, smartphones and other devices requires more and more energy. Some studies show that there will be 41.6 billion connected IoT devices, or "things," in 2025.. The scale factor makes everyday a new challenge for the network to provide this overload of energy.
Persons with disabilities have physical difficulties to practice a sport. That’s a fact. But at Splashelec, we began to wonder if technology could change that. So we decide to use mecatronics to build a control system which will allow disabled people to easily pilot a sailboat. After some R&D, we came back with a joystick servo system which take control of the rudder and the sails.
Do you think your project is the next big thing?
