    This is almost unbelievable. Making an object from a computer picture

    Selective laser/electron beam melting is cooler.

    What's really cool about this is that it doesn't just make a look a like copy. The gears really turn, which means this machine also has to be able to look inside the object.

    LOL, I was waiting for someone to say that.

    It is pretty neat but I dont know how practical it is yet. It reminds me of flying cars...we have had those since the 50s, yet how many do you see actually flying or driving around? The technology is not difficult, but it never became practical.

    I think it would be great in making parts for classic automobiles, where it's next to impossible to get parts. How about making spare parts on the sky lab for those about to break down? Several times they have lost tools working on it. They could make spares, just in case.

    i think a spare screw driver and wrench would be much lighter then a 3-D printer that can make a spare screwdriver and wrench.

    Something tells me that this is not quite the truth. I think this is an april fool joke. It is a three dim printer but you cannot make an object that has moving parts from a static 3d picture.

    Sure you can. Why not? Imagine 2 meshed gears and nothing else. Why is that impossible?

    I don't think you need a 3-D Printer for food, check out Permaculture.

    How would the imager know that the image is of 2 meshed gears? What if the original meshed gears were seized up or not supposed to move? 3d photocopying of solid objects has been around for years but models could not be created but can now.

    I have just found the makers promotional video and they always refer to the 3d image as a model. They also show the model as being solid, hence moveable parts are not constructed.

    The imager isn't the printer. The printer uses a CAD file as input. The purpose of the imager is to create a CAD file from an actual object. Obviously there are limitations of the imager, but the engineer has to know that and correct the CAD file prior to printing, if necessary. It is entirely possible to create a CAD file such that movable parts are, say, 1/100th of an inch apart. Then when it's printed, they will move.

    It's the truth, just type 3-D printer in your search engine and check out the different companies that make them.
