The purpose of this experiment was to improve the Fused Deposition Modeling Process by
examining the tensile strength of samples fabricated in a Stratasys FDM 1650 Machine utilizing
the methods of Design of Experiments. A two-level, four-factor, full factorial experiment was
conducted. The selected factors were temperature, air gap, slice thickness, and raster orientation.
A regression equation determined the level each factor should be set in order to optimize the
FDM machine settings. It was found that single factors - small air gap, small layer thickness
and low raster orientation, as well as the interaction between high temperature and small layer
thickness yielded the greatest effect the response.Mechanical Engineerin
