“FDM/FFF 3D printers, we typically picture a gantry style Cartesian-based machine, or a Delta robot style printer. These machines are capable of 3D printing objects based on three axes: X, Y, and Z. The X and Y axes make up the two-dimensional plane, while the Z axis is the third dimension, allowing for objects to be built up one layer at a time. For one University of Oslo Master’s student, named Øyvind Kallevik Grutle, this just wasn’t enough.”
