In what's believed to be a New Zealand first, musicians have played all 3D-printed instruments in a live concert. The concert was held at Depot Artspace in Devonport, which is hosting an interactive exhibition of the instruments called Synthesis as part of New Zealand Music Month. Lynn Freeman talks to Professor Olaf Diegel from The University of Auckland's Creative Design and Additive Manufacturing Lab, and one of the musicians from the concert, Liam Barr Jones.
