Support Material (FDM)

After reading and hearing about the infinite possibilities of complex structures using a 3d printer one would think it is quite easy to simply create a complex structure layer by layer. Most 3d printers available for the general consumer are based on FDM. However,  what happens if there are overhangs, arches, etc? The printing material would simply drop into emptiness until it hits something solid (the base platform or part of the already printed object). The solution for this is SUPPORT MATERIAL, usually a softer material, different to the object material so it can be easily removed or a water soluble material (i.e. PVA,  Poly-vinyl alcohol).
