According to news on August 24, researchers from Huazhong University of Science and Technology developed a 3D printed permanent non-stick toilet. The surface of this kind of toilet is very smooth. Even after repeated use, almost nothing will stick to it, which can greatly reduce the consumption of flushing water.

3D printed permanent non-stick toilet

It is understood that the surface of the general toilet is designed to be very smooth and coated with a non-stick coating, but the coating often lacks durability and will gradually disappear after being used too many times, and it will no longer be smooth.

A research team from Huazhong University of Science and Technology 3D printed a toilet model that is 1/10 the size of an ordinary toilet. The material used for printing is a mixture of plastic and hydrophobic sand particles. When the mixture is irradiated with laser light, the internal particles fuse to form a complex structure that can hold considerable amounts of lubricant.

The researchers then applied silicone oil, which would penetrate deep into the material and stay there, making the toilet wear-resistant and super slippery.

Researchers poured murky water, milk, yogurt, honey, starch-filled gels and even synthetic feces into them, and none of them stuck to the toilet bowl.

And even after rubbing it with sandpaper more than 1,000 times and subjecting it to destructive tests with files and Stanley knives, the toilet remained as smooth as ever.
