These 3D printed mobiles were made by Marco Mahler, a kinetic sculptor specializing in mobiles, and Henry Segerman, a research fellow in the Department of Mathematics and Statistics at the University of Melbourne. Marco (living in Portland, Oregon) and Henry (from Melbourne, Australia) met each other via Twitter. Segerman was looking for suggestions for one of his 3D printed kinetic sculptures. Several conversations ensued about the possibilities of making 3D printed mobiles, and these beautiful creations are the result of their collaboration. They are made of detached loose pieces connected to each other. The balance points for these mobiles were calculated to 1/1000th of a millimetre. The artists utilize scripts to create the designs that would be very time consuming to be made by hand.
