Evaluation of Shape Registration Algorithms for 3D Print Accuracy Assessment

Unrestricted registration of 3D scanned point clouds of 3D printed parts to CAD models can lead to alignments that underestimate a part's geometric deviations.  This line of research illustrates the magnitude of this bias, and provides a recommended methodology for minimizing these issues.

Shape Deviation Modeling for the Improvement of 3D Print Accuracy Using Machine Learning

Dimensional deviations between a 3D printed part and its intended shape can lead to costly scrap and rework.  This line of research demonstrates a method for quantifying, predicting and prescriptively compensating for a part's errors before they happen using past print data from different shapes and machine learning.
