About Fused Deposition Modeling (FDM):
Fused Deposition Modeling also makes 3 dimensional objects by layers. It uses an extrusion nozzle that first melts the plastic filament or metal wire by heat. The melted materials would solidify immediately after they are extruded from the nozzle, then it builds the objects by depositing the melted materials layer by layer.

The following list of the materials was extracted from Stratasys.
ABS plastics – ABS plastics are formed by three monomers: Acrylonitrile, Butadiene, and Styrene. It is a tough, hard, and rigid thermoplastic material with dimensional stability, machinability, high impact strength, creep resistance, good chemical resistance, heat resistance, and humidity resistance. It is an inexpensive material also ideal for creating products with superior surface quality.
ABSi – a semi-translucent thermoplastic material with higher impact strength than ABS plastics. It is typically used in the transparency-required applications.
Polycarbonate (PC) – a tough and strong thermoplastic polycondensate material with good dimensional stability, impact resistance, and flame retardancy.
4.) MATERIALS USED IN DROPLET DEPOSITION ON POWDER/3-D PRINTING
About 3D Printing:
The 3D Printing technology, originally developed by MIT, used the similar approach as in the FDM processes. Instead of using solid plastic filament or metal wires, it directly deposits the liquid materials in the droplets and from the layers of the object when the liquid droplets solidify after deposition.

One of the Major Droplet Deposition applications is the (DSPC) Direct Shell Production Casting process by Soligen, Inc. The DSPC uses the 3-D Printing technology to produce ceramic molds used in metal casting application layer by layer from the three dimensional CAD designs without any tooling. To learn more about the process of DSPC by Soligen, Inc., please visit Soligen.
Materials Used in Direct Shell Production Casting by Soligen, Inc.:
Ceramic powder and liquid binder.
5.) MATERIALS USED IN LAMINATED OBJECT MANUFACTURING (LOM™)
About Laminated Object Manufacturing:
Laminated Object Manufacturing also makes the 3 dimensional objects layer by layer. It creates the object by using a laser to cut the desired pattern (usually the cross sections of the object) on some sheet materials (such as paper) unwound from a feed roll that are bonded together during the process. The LOM™ process is inexpensive and forms objects that are similar to wood. To learn more about Laminated Object Manufacturing, please visit efunda.
Material Used in LOM™ Processes:
High performance LOM™ Paper
For a more detail description of the LOM materials, please visit the websites of the two major suppliers of the LOM material, SIBCO and Cubic Technologies.
