This project investigated the dimensional accuracy of parts produced using the rapid prototyping method of fused deposition modelling (FDM). Parts with six features common to products were created on a Stratasys FDM2000 out of acrylonitrile butadiene styrene and then measured with a coordinate measurement machine and digital micrometers. An analysis of 12 different dimensions on parts produced using FDM identified that part size, location in the work envelope, and envelope temperature had a significant effect on the dimensional accuracy of FDM.
