Fabrication, is the building of something brand new, that's never been seen before, or invented. Manufacturing, is the duplication of something on a mass scale. Generally, the way it works is, you fabricate something that you need, then manufacture what you fabricate. A good example is, a car company decides to design a brand new car from the ground up.
A fabrication is something made up, like a lie. Telling your boss that the subway broke down when in fact you just forgot to set your alarm is a fabrication. The word fabrication was originally used to talk about manufacturing or construction, and it referred to the act of assembling something. Tires and steering wheels are necessary materials for automobile fabrication.
