Abstract

It is found across all types of 3D printers that there is a discrepancy between the estimated build time of a part and the actual build time of the part. The main cause is difficult to locate, as there are many variables, and so this study attempted to find the root cause of the discrepancy between the 3DSystems ProJet MJP 3600 series and the Client Accelerator used to submit builds and estimate the build time. In many cases, the difference between the Build Time Estimate (BTE) and the actual time is under 10%, but there are a few occasions where the BTE of a part is above 40%. In order to locate the source of this error, a large number of parameters were recorded and their correlation with the difference was tested. It was found that there was an unauthorized pause time in between the part layers, and that time was not calculated in the BTE. That unauthorized time varied, and so the same parameters were compared to the variance in the extra build time per layer in order to find any correlation between the two. It was found that the parameters tested did not have any correlation with the discrepancy, and therefore the parameters measured were not the root cause.
