Abstract
It has been observed by various researchers that parts fabricated by the Fused Deposition Modeling (FDM) process have anisotropic properties. The research presented in the present paper was aimed to study the compression properties of FDM parts and to comprehend their dependence on build parameters. In this study Ultem 9085 was used as the material to fabricate both solid and sparse-build coupons with variations in build direction, raster angle and air gap. A full factorial experimental design was used to study the individual and combined effects of these build parameters on the mechanical properties of the coupons. The mechanical properties studied include compressive yield strength, compressive modulus, compressive strength/mass ratio, and compressive modulus/mass ratio. Besides the obtained test data, qualitative observation and reasoning was used to help understand how the compression properties are affected by the build parameters.
