Automating reverse engineering

Reverse engineering is a common process engineers use to determine how existing products can be improved. Unfortunately, it is a long and often difficult process that involves manually scanning the products with different orientations. The individual orientation scans must then be aligned to form a complete three-dimensional data model of the product. This data is converted into stereolithography (STL) files so they can be printed or further manipulated in MCAD systems. All this effort still leaves off any mechanical features beyond the pure product geometry. However, there is an alternative that greatly improves this process. Automated 3D scanning systems and reverse-engineering software will generate better STL files and save hours of manual work. Some practical applications of this technology include creating accurate heart models for surgeons to practice new procedures. The article reports that the heart models were extremely lifelike with the consistency and response of living tissue. Parts for jet engines are also being scanned and improved with higher tolerances and better performance.  Full article at Machine Design.
