These speakers were designed at Autodesk by Evan Atherton as a showcase of what current 3D printing technology can achieve. They not only sound great they also look great as they contain an audioreactive LED system from LumiGeek
The speakers were 3D printed using an Objet Connex 500 multi-material printer to take advantage of its ability to seamlessly print a rubber material, Objet TangoBlackPlus, and a clear plastic, Objet VeroClear. The rubber base helps reduce the speaker’s resonance and also holds in place the clear crystals.
To demonstrate the possibilities offered by 3D printing Evan designed the speakers so that they could only be produced by additive manufacturing. The project also explored how 3D design tools worked in the 3D printing world and how they could be used in new ways to produce unique objects.
Each speaker takes around 40 hours to produce and equates to about $2,200 worth of Objet printer material. Combined with the fact that you’ll need an Objet Connex printer this puts them out of reach of most home 3D printing hobbyists.
The Lumigeek LED lighting is a Bluetooth-programmable system that uses an Arduino-compatible microcontroller which allows the listener to choose how the LED strip within the speaker reacts to the music being played. LumiGeek started as a Kickstarter project and they intend to move to full production of the light controlling boards soon. A pair of these speakers has been donated to the LumiGeek team as a giveaway for their highest backer level on Kickstarter.
The 3D model of crystal part of the speaker enclosure was designed using Autodesk 3ds Max and exported as an .STL (StereoLitho) file. The .STL mesh was then converted into a solid model using the Autodesk Labs plugin Mesh Enabler for Autodesk Inventor.
If you want to have a go at creating your own speakers you can find a guide at Instructibles.
Here is a video of the speakers in action, and the second video gives you an insight into how the speakers were developed.
