In an era where every drop of water counts, a team of Chinese researchers are flushing old concepts down the drain with their revolutionary new invention – a non-stick toilet bowl. The scientists at the Huazhong University of Science and Technology have developed an innovative toilet bowl that repels almost any substance. This development could potentially render the humble toilet brush obsolete and drastically reduce the amount of water wasted in maintaining hygiene.

Their groundbreaking research involves the use of 3D printing technology to create an Abrasion-Resistant Super-Slippery Flush Toilet (ARSFT). This unique contraption demonstrates an extraordinary ability to keep itself clean, even when exposed to various liquids such as milk, yogurt, and highly sticky honey. Notably, the ARSFT still maintains its super-slippery capability even after enduring 1,000 cycles of abrasion, an advancement that could significantly impact the development of super-slippery materials and water conservation efforts.

A New Era of Toilets: Super-Slippery Surfaces to Save Water

A team of Chinese researchers at Huazhong University of Science and Technology has developed a non-stick toilet bowl that could consign the toilet brush to the annals of history. This new development could revolutionize the way we clean our toilets and save a significant amount of water in the process.

The Advent of the Super-Slippery Toilet

The researchers utilized 3D printing technology to create what they have termed an abrasion-resistant super-slippery flush toilet (ARSFT). This toilet bowl surface repels almost any substance, as demonstrated by videos showing "dyed synthetic feces" effortlessly sliding down the bowl.

The team explains that a significant amount of water is wasted daily flushing toilets due to the unavoidable adhesion of human waste to toilet surfaces. Traditional super-slippery surfaces, while able to repel complex fluids and viscoelastic solids, are vulnerable to damage by mechanical abrasions.

The Science Behind the Slip

The paper, published in Advanced Engineering Materials, elaborates on the innovative technique. The researchers have leveraged a powder-sintered strategy to not only give the ARSFT a self-supporting 3D complex shape but also a porous structure. This structure can hold a considerable amount of lubricants, thus ensuring the surface remains super-slippery even after substantial use.

In their tests, various liquids, including milk, yogurt, highly sticky honey, and starch gel mixed congee, were effortlessly repelled by the ARSFT. The team also found that the ARSFT demonstrated a high resistance to sticky synthetic feces.

Towards a Water-Efficient Future

What’s noteworthy is the resilience of the ARSFT. Even after 1,000 abrasion cycles using sandpaper, the toilet maintained its super-slippery capabilities. This development could have far-reaching implications for the development of super-slippery materials, leading to significant water savings in society.

The researchers believe that the concept of a 3D-printed object with superior abrasion-resistant slippery ability could pave the way for future advancements in this field.


This breakthrough in toilet technology not only has the potential to make toilet brushes obsolete but also promises a significant reduction in water consumption. The ARSFT’s resistance to both liquids and synthetic feces, along with its resilience to abrasion, is a testament to the advancements in 3D printing technology and materials science. While it may seem like a small step, innovations like this can contribute significantly to water conservation efforts worldwide.
