The traditional porcelain and ceramic toilet bowls could be on the way out, if a new 3D-printed design from scientists at the Huazhong University of Science and Technology in China catches on – with the key benefit being the ultra slippery surface.Poop that clings to the toilet bowl is not only unpleasant for bathroom visitors and cleaners alike, it actually wastes a significant amount of water as more flushes are required to dislodge the stuff.It was this problem that the scientists wanted to tackle by making a non-stick toilet bowl. They used a mixture of plastic and hydrophobic sand grains for their material, fused together with laser-based 3D printing techniques, in a design that was around a tenth the size of a standard toilet bowl.
