Here on planet Earth, most of us can’t start our day off until we’ve had a sip of that initially cup of coffee, and the astronauts in the International Space Station are no various. But due to the microgravity in the ISS, these astronauts generally have to drink swift coffee of a bag with a straw (yuck!). 3D printing advancement has dabbled in the world of coffee on really a few occasions, whether it be through caffeinating 3D printing devices with a coffee-based filament or conjoining a 3D printing keep with a cafe in Berlin.

Now, a graduate student in the Mechanical Engineering program at Portland State University , named Drew Wollman, has utilized 3D printing advancement to donate the ISS astronauts a new and improved way to brew and drink their coffee. ISS astronaut Kjell Lindgren got in contact with Wollman, and his professor Mark Weislogel, after discovering their zero-gravity espresso cups in Wired Magazine’s The Most Cleverly Designed Objects of 2015.
And so, via a 3D printing device, Wollman and Weislogel made a new espresso cup equipped with a adjusted brewer attachment, called (by Lindgren at least) the Capillary Beverage Cup. A syringe filled with hot water is pumped through an attached K-Cup, that produces freshly brewed coffee directly into the printed espresso mug. The geometry of the espresso cup produces a surface tension that brings the freshly brewed coffee right to the lip of the cup, yet remains held in place inside the 3D printed device. But coffee is pretty an significant part of approximately anyone’s day, the geometric create of Wollman’s 3D printed cup may lead to actually greater advancement for these astronauts.
“We’ve been testing this cup up here as a way to see how fluids flow,” Lindgren said in the YouTube video presenting Wollman’s device. “The applications for a thing like this are pretty immense. If you can move fluids without having to use a pump, mechanical moving parts, or electricity and power, that is highly beneficial for a process like the space station.”
The method created by Wollman and Weislogel has pretty stirred up the excitement on the ISS (as you can tell by the giddy Lindgren in the video above), who can now freshly brew their coffee actually while living and working 250 kilometers above the planet Earth. And who knows what other advancements this 3D printed espresso device can lead the ISS astronauts to? I’m certain their minds can be actually sharper and additional awake now that they can start their day floating around with a fresh cup of joe.
