Amun 3554 is a little more than a mile wide and it’s one of the smallest M-class (metal-bearing) asteroids yet discovered. Unless it ever decides to smash into us — a theoretical possibility, but extremely unlikely over the next few centuries — it will continue orbiting the sun, unknown and unmolested.
Dutch designer Joris Laarman will build a bridge in 2017 by wheeling a robot to the brink of a canal in Amsterdam. He will push an “on” button and then walk away. When he returns in two months, the Netherlands will have a new, one-of-a-kind bridge, 3-D printed in a steel arc over the waters. This isn’t some proof-of-concept, either: when it’s done, it will be as strong and as any other bridge. People will be able to walk back and forth over it for decades.
Graphene is pure carbon arranged in sheets that are only one atom thick.
The startup, 3D Graphene Labs, hopes to develop not only graphene materials for 3D printers, but a 3D printer designed for graphene printing. But we’re not so sure.
Together the Israeli company, Phinergy, and the aluminum giant, Alcoa Canada, demonstrated an electric vehicle (EV) capable of driving over 1,100 miles between charges using a combination of aluminum-air and lithium-ion storage technologies.
We are able to 3D print plastic goods, fabric for clothing, food, and possibly in the future, human organs. But metal has been less accessible. Now, a collaboration between Dutch designer Joris Laarman and software company Autodesk has yielded something groundbreaking: an affordable technique for printing large metal structures, called MX3D-Metal.

The Mini Metal Maker prints 3D objects from digital files directly in precious metal clay, rather than in plastic. Once these clay objects air-dry, they are fired in a kiln to produce beautiful solid metal objects of high purity and precision. Using metal clay essentially replaces the entire wax-casting or lost-wax process ordinarily needed to do this. The Mini Metal Maker will add new capability for the DIY inventor or artist by making fabrication in metal easy and direct. It will be a boon for anyone interested in creating their own gears, miniature mechanisms, or printing detailed jewelry or metal ornaments. The Mini Metal Maker is built around the concept of using the minimum number of parts, reducing the cost to produce and also eliminating many chances for error during assembly.
Solid Concepts 3D printed metal gun.
The first 3D printed gun was the Liberator pistol. Then came the Grizzly, a 3D printed rifle. Now a third one has surfaced, and it’s a doozy. This one is printed entirely out of metal and the gun’s design was copied from a classic 1911 model. (Video)
Concept of a Mars probe.
The European Space Agency has unveiled plans to “take 3D printing into the metal age.” They will be building parts for jets, spacecraft and fusion projects. The Amaze project brings together 28 institutions to develop new metal components which are lighter, stronger and cheaper than conventional parts.
MIT has had a number of off-the-wall discoveries, so it takes something truly unexpected to throw the researchers there for a loop. MIT researchers have recently discovered the self-healing properties of metal. If their discovery means what we think it means, we could just have witnessed to the birth of the T-1000.
With a major winter storm set to hit much of the U.S., this seems to be an appropriate time to share photos from The British Museum illustrating how mankind has coped with winter in earlier periods.
This one comes from Salekhard, made of “metal, cloth, skin (reindeer, with fur), brass, beads, and buttons (brass).”

Inkless Metal Pen
When we think about the substances used for writing, it’s usually either graphite or ink. But here is a pen with an endless supply of metal “ink”. The only pen you will ever need.
World’s Largest Gold Coin
Behold the largest gold coin in the world. This one million dollar Canadian gold coin weighs 220 lb and is worth about four times its face value. And now it’s up for sale:
The 100-kilogram Gold Maple Leaf was, in fact, recognized by Guinness World Records in October 2007 as the planet’s largest gold coin.
