How Does A 3 D Printer Form A Particular 3D Image - Any Ideas?

Would it be hard to learn how to use a 3D printer? Surely it wouldn't be any more difficult than learning to use a regular photocopy machine, just set the machine to the number of copies that are required, push the button and wiz bang out come the copies in the paper tray. That's assuming of course that the paper doesn't get jammed then things might take on another form, and get a little bit stressful, especially if the copies were urgently needed.

By and large one would imagine knowing how to take copies with a 3D printer would be just as straight forward, after all people don't need to know the rudiments of light bulbs and electricity to turn a light switch on do they, but is there more to the 3d printing process than meets the eye, who came up with the idea and from where did it originate?

3D imagery and CAD or computer aided design was the brainchild of a pioneering art designer called William Fetter of Independence Missouri. He studied art design at the University of Illinois in the fifties and evolved into putting early computers to work in assisting the creation of 3D drawings. He and his boss at Boeing in Seattle, were responsible for creating the very origins of CAD. Who can now imagine a world without 3D, it's almost quite unthinkable isn't it?

Additive manufacturing or 3D printing from a 3D printer is really about creating solid 3 dimensional objects from a digital file. The additive process required for this to materialize comes from successive layers of material being laid down until the entire completed object is produced.

Think of it like looking at a horizontal snap shot of the earth's crust, with all its different composites, each one representing a different thinly sliced layer until it reaches the earth's core and creates the completed object, in this case the earth's crust. Get the picture? These are the basics of how the process works.

A virtual design of the object required is created in a CAD or Computer Aided Design along with the assistance of a 3D modelling program if it's a new object being created or if an existing one, with the use of a 3D scanner which in turn puts it in a 3 D modelling program, Pretty cleaver stuff eh?
