For providing the facilities, materials & information making
this research project possible.
Orientation based print flues was characterized and can help
post processing
Different build orientation
will effect part’s fill type
result different measured
deviations.

Research Project – 3D Printing
Building Strategy &
Geometric Tolerances
A linear function showing measured deviation of printed parts
built in different orientation resulting different fill type pattern
The present study deals with the
influence of printing parameters and
orientations on Dimensional Accuracy
of 3D printed ABS samples using the
FDM technology; the results may help
the printer’s technician to minimize
geometric deviations by choosing the
suitable building orientation.
