Fused deposition modeling (FDM) was developed by Stratasys Inc. and is executed
on machines called the FDM 1650,
2()(M),
or
8()(M)
series. Figure 4.9 shows that the
material is supplied as a filament from spool. The overall geometry and system are
reminiscent of icing a cake. The filament melts as it flows through a heated delivery
head and emerges as a thin ribbon through an exit nozzle. The nozzle is guided
around by CNC code. and the viscous ribbon of polymer is &fadualJ.y~,uiJtup from a
