Previously, different materials were used for printing on 3D-printer: glass, organics, synthetic fibers, and more. Now students from McGill University in Canada have been able to apply the most common liquid on Earth: water.
They modified a relatively old Fab@Home Model 1, having replaced the extruder with liquid feed system. To prove the efficiency of technology, the team produced a gigantic mug and a few smaller ice sculptures. The official purpose of the project is to explore alternative ways of creating complex architectural models. But why making architect models that melt? However, the tourism might be the area with a good opportunity to earn money: imagine such machines in public places, selling soft drinks, bottled in icy mugs, shape of which customer could choose. Interesting, huh?
