“Building a house by hand can be both time-consuming and expensive. Some homebuilders have chosen to automate part of the construction instead.”
A bold plan to rev up off-Earth manufacturing is about to get a big test.
A small, privately built machine designed to make optical fiber is launching toward the International Space Station (ISS) aboard SpaceX’s Dragon cargo capsule tomorrow (Dec. 12).
If all goes according to plan, this little factory — which is owned by California-based startup Made In Space — will churn out stuff that’s good enough to sell here on Earth, opening up space to greater commercial use. [3D Printing: 10 Ways It Could Transform Space Travel].

Scientists have developed new 3D-printed plastic objects that can hook up to Wi-Fi without the aid of any electronics or batteries, meaning household devices could get a lot smarter in the future without the need for any circuitry.
If that’s not blowing your mind just yet, think about this: the tech could be used to make a laundry bottle that orders a refill online as soon as it runs out, or a simple volume slider that connects to your speakers without any cabling or even a power source.
3D printing has come a long way. In a new study, scientists explore the potential of using bacteria-laced ink to print living materials.
From pizza to urine-based space plastic and even blood vessels, it seems there’s no limit to what can be 3D printed. A new 3D printing platform, created by ETH researchers led by Professor André Studart, head of the Laboratory for Complex Materials, is advancing the process by working with living materials. The specially designed material is actually an ink infused with bacteria. The machine is then able to print living biochemical designs for a wide variety of purposes, which vary depending on the bacteria used. Their research has been published in Science Advances.
A team at MIT has genetically modified bacteria cells and developed a new 3D printing technique to create a “living tattoo” that can respond to a variety of stimuli.
Electronic tattoos and smart ink technologies are showing exciting potential for reframing how we think of wearable sensor devices. While many engineers are experimenting with a variety of responsive materials the MIT team wondered if live cells could be co-opted into a functional use.

The soft artificial heart was created from silicone using a 3D-printing, lost-wax casting technique; it weighs 390 grams and has a volume of 679 cm3. “It is a silicone monoblock with complex inner structure,” explains Cohrs. This artificial heart has a right and a left ventricle, just like a real human heart, though they are not separated by a septum but by an additional chamber. This chamber is in- and deflated by pressurized air and is required to pump fluid from the blood chambers, thus replacing the muscle contraction of the human heart.
