3D printing is an additive form of manufacturing. It has a lot of advantages and disadvantages, by my understanding throughout this week, I have listed some below. Like Neil says, 3D printers are to FabLabs, what microwaves are to kitchens. They can do some parts but not replace all of manufacturing.
First advantage is that waste is minimised, because you use only the material that is required in the final product.
It is ideal for rapid prototyping, as it can make complex geometries that you traditionally need more than one processes to make. It is good for custom and small-scale mass customization production processes, but not necessarily for mass manufacturing. It also doesn't have the best accuracy and tolerances, so not ideal for applications where precision is important.
The most widely used technology for 3D printing is Fusion Deposition Modelling (FDM). I will use FDM printers this week. There is also SLA, Stereolithography and Powder Bed Printing 3DP.
This presentation from Santi is a good resource for the subject.
