Music to His Printer Music to His Printer Music to His PrinterLaurent Bernadac has two passions engineering and playing the violin. Both require a sharp concentration and are an art to be respected. However, for most of his life, he assumed he could not combine the two.But now he has, with his 3D-printed violin.The 3Dvarius was born in 2012, he says. I was a student in a mechanical engineering university called INSA and based in Toulouse. Im also a professional violinistI began the violin at four. I decided to create an electric violin that was corresponding to my playing style.But at first, he didnt know to design it. I searched about it and based my design on the planes of a real Stradivarius, says Bernadac, who previously worked for a hydropower firm in dienstgrad of restoring a hydropower factory. And after three prototypes, and many different 3D models, I reached the final model, which is fully playable. The third prototype utilized a stereolithography 3D printer.Laurent Bernada c spent years designing 3Dvarius. Image 3DvariusDesign ChallengesAccording to Bernadac, the biggest challenge in the process was to ensure the solidity of the neck of the violin against the strength of the four chords stress. Then I had to keep the mandatory shapes of a classical violin to keep it fully playable for a classical violinist, he says. The weight of the violin is very important, too. It has to be as light as possible. So I had to design a lattice on the back of the violin to keep it strong and light.To design this lattice, he had to check the mechanical solidity of the violins body. He accomplished this with RDM6 software, which computes the deformation of the piece against the stress of the chords, he says.A classical violinist can play it because all of what he deems the mandatory shapesneck, chinrest and bridgeare present, he says. But, as a conventional electric violin, it has no soundboard, he says. The sound goes directly from the chords to the bridge without losin g its power. But electric violin is not really like a classical violin. Its like electric and acoustic guitars. You have to play it differently according to the sound and the effect you want to obtain.Listen with PatienceBernadac says 3D printing objects are used by musical instrument producers to create only prototypes, but he believes it will eventually lead to creating final instruments. And maybe totally new instruments with totally new sounds, he adds.He says electric violins cant be used like you would a conventional violin and easily insert it into a symphony orchestra. But I think that all actual instruments will be 3D printable in a few years, he says, And maybe we will be able to listen to fully 3D printed musical bands.Eric Butterman is an independent writer.Learn mora about the latest trends in 3D printing at AM3D Conference and Expo.
