FDM or Fused Deposition Modeling is said to be one type of a free-form fabrication technologies being developed Stratasys Inc. As this technology utilizes high force ABC plastic it is one of the most preferred technologies for prototyping plastic parts which require force. The Fused Deposition Modeling is a method of layered manufacturing which extrudes a very thin drop of plastic, just one layer at a time. A string of plastic is supplied into an extrusion cranium where this string is heated into a state of semi-liquid form and then extruded via a very tiny passage onto the other layer of the substance. Support substance is even being laid down in the same method.
