I really want to learn what it takes to execute projects using the 3D printer. Simply put, I want someone who can tell me what it requires to have all the knowledge of 3D printing. I see it as the future of manufacturing.

@Kenneth_Ikebunna it does not take very much to start off. There are now printers available for a decent price, already assembled and working. I presume these printers include software to process the 3D images of the objects you design, so all you really need is to master some concepts of mechanical design (or artistic ideas for sculptures if you’d rather use 3D printing for the manufacturing of art objects, but since you talk about the future of manufacturing, I presume you’re more likely to use them in an industrial context). and some practice with one of the numerous 3D design software packages.
If you haven’t looked at it yet, head to http://www.reprap.org for lots of links to forums and information about 3D printing,

You need to learn how to make .CAD files.

Google SketchUp (http://sketchup.google.com/) is the easiest one to use and it is free.

Blender (http://www.blender.org/) is also a good 3D design tool which is also free.

I personally use AutoCAD (http://students.autodesk.com/) which has a 3 year free trial for student.

@Kenneth_Ikebunna you need to goto http://reprap.org and read EVERYTHING! You can also follow @Learn3DP_3D_Printer

@Kenneth_Ikebunna Have a look at this book: http://www.3ders.org/articles/20130501-ictp-scientists-publish-free-downloadable-book-low-cost-3d-printing.html
