MakiBox A6 aims to bring affordable 3D printing to the desktop

By Randolph Jonsson

Over the past few years, the price of desktop 3D printers has been falling thanks to devices such as the uPrint, MakerBot, Printrbot and Cubify ). But designer Jon Buford's thoughtfully-conceived MakiBox looks to be the least expensive yet. He and his team have now pre-sold enough of the device to make the move from prototype to market and the result looks rather promising. If all goes well, the US$300 printers (plus US$50 for global shipping) could be available for delivery as soon as the end of the month.

The 280 mm x 210 mm x 210 mm (11 x 8.27 x 8.27 in) self-contained MakiBox has a footprint about the size of a piece of standard letter paper, yet can build objects up to 150 mm x 110 mm x 110 mm (5.9 x 4.3 x 4.3 in) in size - about a quarter of the printer's overall volume. Replicator G, an open source 3D printing software application compatible with Windows, Mac and Linux, drives the printing process during which spooled 1 mm (0.04 in) diameter polylactide (PLA) plastic filament is melted and extruded in thin layers at 60-80 mm (2.36-3.15 in) per second.

The Pirates! 3D Printing Now Used for Animated Films

The Pirates! is the first animated film to embrace 3D printing on a large scale.
Characters of the new Sony Pictures movie have been partly created with 3D printing technologies. In order to make the Pirate Captain and his shipmates talk, artists of Aardman Animations 3D printed not less than 8000 mouths!
Key animator Ian Whitlock told Fox News that they build 257 separate mouths for the Pirate Captain and about 130 for the Charles Darwin model.
It was a real gain of time and allowed stronger animation styles to each face. Even if hand-molded plasticine is still used for most of the parts of the characters (the eyes for example), Aardman team was deeply impressed by the quality of 3D printing, mostly for creation and time purpose.

Vortex gun blows rings of high-speed electrified gas – could have numerous applications

By Ben Coxworth

While something called a "vortex gun" might sound like a device from science fiction, the fact is that they have been available as novelties for years - if you've ever used a toy gun that shot out a smoke ring, then you've used a vortex gun. Lately, however, scientists from the Ohio-based Battelle R & D group have developed one that could have practical uses for people such as firefighters, exterminators and riot cops.

Vortex guns work by forcing air or another gas at a high velocity, down the inside of a cylinder. Friction along the inside of that cylinder wall slows down a thin layer of that flowing gas, causing it to roll forward on itself. By the time it exits the cylinder, it's formed into a self-contained donut shape, which it is able to maintain as it flies through the air - even when subjected to cross winds.
