Solid freeform fabrication has the potential to affect both financial and environmental
concerns for manufacturing enterprises. However, when planning for installation of a new machine
tool, accurate energy usage estimation relies heavily on the data and model selections of the
estimator. This project used a variety data sources and model decision options to examine the
spread of energy consumption and global warming potential estimates for a fused deposition
modeling machine. In addition to primary and secondary data sources, the use of similar machines
was explored as proxy estimates for the target machine. A Monte Carlo simulation was constructed
to vary the model selections, machine utilization, and data sources. The results indicated data
sources and model decisions had large effects on the output and that most model estimates were
low.
