If only harmonica players had three hands, they would be able to easily hold a microphone while using their other two hands to play. Just ask Dror Adler from the world renowned Adler Trio. Fifty years after he started performing, Adler came up with an idea to develop a unique microphone enclosure that would attach to the harmonica and accommodate all the necessary electronics for a wireless mike.
The first prototype was produced by Israel-based Erez RP on a PolyJet-based Stratasys 3D Printer. Several design iterations were created until a perfect prototype was produced and Dror was in harmonica heaven. After other musicians saw the Adler Trio performing live, and asked where they could buy their own microphone holder, Dror began to consider producing them in small commercial quantities.
Again, Stratasys 3D printing was music to his ears. This time Erez RP used a silicone molding process, where a mold is created by pouring liquid silicone rubber over a Stratasys 3D printed part, for economical production of about 10 to 15 parts in each run. The silicone mold is used over and over, every time Adler receives a new order.
