Not really. But evaporating whisky is just the job for inspiring new 3D printing inks and coating materials, according to a research team at Princeton University in New Jersey, USA.

The team of physicists began investigating the drying properties of whisky after noticing that, unlike coffee, most whisky glasses don't leave a ring mark on the table. They discovered that whisky has fat-like molecules that lower surface tension and stop the liquid pulling to the edges of the glass. They also discovered sticky plant-derived polymers that helped keep the evaporated liquid in its place.

So, what does this have to do with 3D printing, we hear you ask? Well, fluid patterning manipulation is very important for various physiochemical applications. Being able to recreate the properties of whisky in other liquids would give researchers more control over such liquids' behaviour and distribution. This is attractive to companies that use industrial liquids for coating purposes and for creating 3D printing inks that have predictable drying properties. The next step, dear readers, is to add the whisky-based principles to industrial fluids and, in turn, hopefully add a whole new dimension to ink-based 3D printing.
