The Easy Cheese printer is back, and it’s better than ever! Initial testing of the printer proved humorous at the least. If you haven’t seen it already you can check out the original video here. The machine’s creator; Andrew Maxwell-Parish has gone a step further and removed the printers need to follow directions from a computer program by integrating an extrusion start/stop switch and a leap motion controller to direct the nozzle in the X, Y and Z planes making it like a cheesy Etch A Sketch. Now where did I put those crackers...

Researchers at the Wake Forest School of Medicine have created the world's first beating heart cells called Organoids using 3D Printing.

The cells are created by genetically modifying adult human skin cells into induced pluripotent stem cells, which are then redesigned to form Organoids. The spheroids of these Organoids are then 3D printed using a specialised printer at the Wake Forest Baptist Medical Center For Regenerative Medicine.

The team behind the project explained that the cells must be kept at the same temperature as the human body to enable them to beat in a pattern which can be altered by chemical or electrical cues.

The $24 million project aims to create several types of 3D printed lab grown organs which can be used to perform the functions of their human-grown counterparts.

We heart this!

Coffee is everywhere these days, you can’t turn a street corner without happening upon several coffee joints vying to fulfil your caffeine fix. But what about in space you say? Well now leaving the planet won’t entail the struggle of sourcing some fresh jo, hurrah!

Italian firm Argotec along with the Italian Space Agency have developed the ISSpresso machine which can produce coffee in the gravity barren abyss of space. The lack of gravity also posed the problem of containing the coffee for drinking, which would just float out of an ordinary cup. Fear not, a Professor in the Thermal and Fluid Sciences Group at Portland State University, Mark Weislogel, colleague Drew Wollman and high school student Nathan Ott took charge of creating a drinking vessel that could be used aboard the International Space Station. They created an innovative new design based off one which astronaut Don Pettit devised around 7 years ago while spending time on the ISS. It creates enough surface tension to keep the coffee inside the cup in a zero-gravity environment and because of the complexity of the cups geometry, they chose to use 3D printing to fabricate it.

"The shape of the container can passively migrate fluid to desired locations without moving parts -- using passive forces of wetting and surface tension," said Weislogel. "Its geometry is the 'smart' part, which operate the fluids-control system without requiring pumps or centrifugal forces." He added.

Samantha Cristoforetti, an Italian, European Space Agency Astronaut brewed the first cup of espresso on the ISS and subsequently tweeted; “Coffee: the finest organic suspension ever devised. Fresh espresso in the new Zero-G cup! To boldly brew...”

Bean me up Scotty!
