Creaform Makes Scan-to-CAD Seamless For Additive Manufacturing

There are numerous reasons to combine 3D scanning and 3D printing. Reverse engineering and its ability to customize and reconstruct obsolete parts is just one example of the versatility of the duo. While high-quality 3D scanners can capture detailed geometry, transforming that raw scan data into a clean, parametric CAD file suitable for printing is another challenge entirely. Furthermore, converting scan data into a usable CAD file for further processing can be both time-consuming and labor-intensive. In a world where everything seems to work at the touch of a button, this is no longer appropriate. Scan-to-CAD solutions that simplify the transition from scan data to CAD models, thus eliminating efficiencies and enabling companies to overcome various obstacles, are the key.

Let’s first take a look at why the transition from scan-to-CAD can be full of hurdles when using traditional processes. Once the scan has been successfully completed, the data needs to be cleaned up and prepared for further processing. The first step is to align the scan data correctly. Without proper reference points, alignment issues can occur which, in turn, lead to dimensional inaccuracies, causing users to lose time when making adjustments. Secondly, it is important to clean the scan data, as raw data contains noise or gaps that are unnecessary for further processing and could also affect the accuracy of the CAD model. Additionally, converting mesh-based scans into smooth, parametric CAD models is especially challenging for complex or organic shapes, adding further complexity to the process.

Needless to say, quality assurance steps take a significant amount of time, often requiring switching back and forth between different capture tools and CAD software. This time-consuming process is also costly, potentially delaying product launches and requiring trained professionals. So how can a seamless, efficient transition from scan data to CAD model be achieved?
