Artificial molecules

Scientists at ETH Zurich and IBM Research Zurich have developed a new technique that enables for the first time the manufacture of complexly structured tiny objects joining together microspheres. The objects have a size of just a few micrometres and are produced in a modular fashion, making it possible to program their design in such a way that each component exhibits different physical properties. After fabrication, it is also very simple to bring the micro-objects into solution. This makes the new technique substantially different from micro 3D printing technology. With most of today’s micro 3D printing technologies, objects can only be manufactured if they consist of a single material, have a uniform structure and are attached to a surface during production.

To prepare the micro-objects, the ETH and IBM researchers use tiny spheres made from a polymer or silica as their building blocks, each with a diameter of approximately one micrometre and different physical properties. The scientists are able to control the particles and arrange them in the geometry and sequence they like.

The structures that are formed occupy an interesting niche in the size scale: they are much larger than your typical chemical or biochemical molecules, but much smaller than typical objects in the macroscopic world. “Depending on the perspective, it’s possible to speak of giant molecules or micro-objects,” says Lucio Isa, Professor for Interfaces, Soft matter and Assembly at ETH Zurich. He headed the research project together with Heiko Wolf, a scientist at IBM Research. “So far, no scientist has succeeded in fully controlling the sequence of individual components when producing artificial molecules on the micro scale,” says Isa.

International ‘Moon Village’ Is Way To Go According To European Space Agency | Video

Sounds great — as long as we don’t call it a Moon Village. That sounds inane.


The director general of ESA, Johann-Dietrich Woerner, believes that the world should collaborate to create a permanent lunar base for “science, business, tourism or even mining.” Plans to use robotics and 3D printing for building the base have been discussed.

Fear Not The Drone Apocalpyse

When the apocalypse comes, it won’t do so on four rotors. Drones, especially drones-as-we-know-them—the affordable, commercially available quadcopters—are only really engines of their own destruction. Zoltan Istvan, transhumanist candidate for President, wrote today that the American constitution is unprepared for the challenges of swarming robots. With all due I respect, I couldn’t possibly disagree more.

The Second Amendment Isn’t Prepared for a 3D-Printed Drone Army”, Istvan argues, and vividly sets a scene of total despair:

First Retailer in Orbit: Lowe’s and Made In Space Send 3D Printer to Station

Outer space is about to get its first pop-up retail shop.

Lowe’s, the home-improvement store, has teamed up with Made In Space, the company behind the world’s first zero-G 3D printer, to launch the first commercial manufacturing facility on the International Space Station.

The Additive Manufacturing Facility (AMF), as it is called, is an advanced, permanent 3D printer that will be available for use not only by NASA and its station partners, but also by researchers, educational organizations and commercial customers.
