RC car 3D printed : Biologically-influenced truss structures
Max Greenberg, Sameer Yeleswarapu, Ian Cullimore have developed the 3D printed ‘cirin’ RC car at the art center college of design. The car is powered by a 16-foot rubber band that propels it at upwards of 30 mph for a few hundred feet. The structure is inspired from mid 1950’s formula 1 cars as well as the biologically-influenced truss structures found inside the bones of a birds wing. These structures are both light and rigid.
The mechanical layout was arranged in Solidworks and the manufacturing is utilizing selective laser sintering of a proprietary nylon powder formulation, the form was freed of all geometric constraints, without compromising engineering grade material properties. A single unibody construction ensured highly controlled tolerance of mechanical components and a nearly complete elimination of fasteners. The bio-truss structure is built to withstand the immense torsional stress put on the frame by the wound band.

WinSun China builds world's first 3D printed villa and tallest 3D printed apartment building
The company Shanghai WinSun Decoration Design Engineering Co, has built the highest 3D printed building, a 5-storey residential house and the world's first 3D printed villa. The villa measures 1,100 square meters and even comes complete with internal and external decorations. The 3D printing villa was specially designed for Tomson Group, one of the most well-known Taiwanese-owned real estate company. The total costs attached to printing this villa amount to more than 1 million yuan ((161k USD), though 10 sets have already been pre-ordered.

"Continuous" 3D printing
There are a few different types of existing 3D printers, but they mostly work via the same principle: a printing head passes over a platform over and over, depositing layer after layer of a material like plastic in a precise pattern. Over time, these layers combine to form the desired object — much like a paper printer forms text on a page by putting down row after row of ink.
By contrast, this new continuous 3D printer would do away with the layers entirely. Instead, a platform draws the object continuously out of a bath of liquid resin. The resin solidifies when ultraviolet light hits it (a process called photopolymerization). So to create the desired item, a projector underneath the resin pool shoots UV light, in the form of a series of cross-sectional images of the object. Light, in a sense, is the blade the printer uses to sculpt its products.
Meanwhile, oxygen prevents this reaction from occurring — so to stop the object from simply hardening and sticking to the floor of the pool, there's a layer of dissolved oxygen there, creating an ultra-thin "dead zone" at the very bottom.
As a result, it works in minutes rather than hours — 25 to 100 times faster, its creators say, than conventional 3D printing.
