Establishment of Select Printing Parameters for Low-Cost Fused Deposition Modeling Printed Cast Iron Through Experimental Optimization.

The fused deposition modeling (FDM) form of additive manufacturing provides a low-cost opportunity to quickly create unique parts with complex geometries using a high degree of precision. This is accomplished through a layer-by-layer extrusion of a metallic infused thermoplastic from a heated nozzle onto a build plate, until the 3D part is achieved. The ability to produce cheaply manufactured FDM printed cast iron parts would allow industries to bypass casting lead times and create custom cast iron parts without a machined mold.
