Hello, here's some more images of cool stuff.

This is a model that can be downloaded from Thingiverse. It is a tank that is based on an existing type of fan belt. All of the components except the motors and nuts and bolts are printed. Looks like a fun little machine. Seems to be missing a control unit though, but one may be able to take one from another remote control vehicle.

This image is of a recreation of shark skin printed by in 3D. Bio mimicry will be an important source of technological breakthroughs for the future. This reproduced skin managed to cause a significant reduction in drag and energy required for propulsion. This could be applied to any number of water craft or even vehicles that travel through air.

This printer is the latest release fro Airwolf. It can maintain higher temperatures at the printer head enabling it to use higher grade materials like nylon. This machine is at the high end for consumer printers and is almost commercial grade. The fact that it can use quality materials and it's large print area makes this a very desirable model. When I purchase a printer it will be at least of this spec.

This image is of a concept prototype. It wasn't made to be entirely functional but I think it's a pretty cool idea and wouldn't take much tweaking to make it a proper product. I can think of two things that would make this a good item to use, first would be the more comfortable position you could hold the phone at and using the right materials you could cut down radiation from the phone making it safer to use.

I like this model of a motor because in the future 3D printers will be able to produce items like this that are comprised of multiple materials and parts. This will make a large difference to how consumerism works probably reducing the retail market, but opening new avenues like material supply and object design.
