ABSTRACT
Fused deposition modeling (FDM) is an extrusion-based rapid prototyping (RP) process, although it works on the same layer-by-layer principle as other RP systems. Fused Deposition Modeling relies on the standard STL data file for input, and is capable of using multiple build materials in a build/support relationship. FDM was developed by Stratasys, Inc. of Eden Prairie, MN, in the early 1990s as a concept modeling device that is now used more for creating casting masters and direct-use prototyping.
