In an interview, Edward Jay described his invention:
“My concertina is almost entirely fabricated on a 3D printer, meaning that it’s made of mostly plastic. In the prototype, only the reeds and bellows are made in the traditional way, though I am quite close to fabricating these on a 3D printer too.”
“3D printing has been around for a while actually, but only recently has it become more accessible and affordable. For example, the printers I am using now cost £800 each. But 3D printers aren’t exactly quick; to give you some idea of speed, each part on my instrument can take between 1 and 12 hours each to print. So having a farm of printers beavering away can speed things up significantly.”
“That said, it takes just 2 days for 3 printers to print all the parts for a single instrument, which I think still is a significant edge on the time required to fabricate all the parts using traditional methods. Actually, I understand it takes something close to 3 months to make a new traditional concertina—as long as my entire prototype development period.”
“Interestingly, I’ve somehow managed to create a concertina sound, I believe, due to my material choice, because 3D plastic is hollow! If you didn’t know, early concertina insides were made of balsa wood, or similar woods, woods that were chosen rather for their lightness than their integrity, which I believe in part gave traditional concertinas their signature sound.”
“This is not a toy at all. Every part of it is engineered properly; the stresses and strains, the tension forces, and so on, everything has been accounted for. So it won’t break. This concertina is very solid.”
