In the additive manufacturing field, the two main quality values of a 3D Printing system are Productivity and Dimensional Accuracy. The cooling process, which may take several hours to finish and requires some user interaction at certain point of the process, is one of the main contributors to the dimensional variability of the 3D printed parts. A repeatable cooling process highly improves the dimensional accuracy, and we can generally control the process during the week when the 3D printer operators are available.

However, several manufacturing lines stop their production during the weekend, so the last printed job of the week will have a much higher cooling time because no operator can extract the printed parts at the appropriate moment, affecting the dimensional accuracy.

In this document we present an idea to overcome this limitation and pre-compensate the part shrinkage that occurs during the cooling phase depending on the expected cooling time, achieving a more repeatable and accurate quality.
