3D Optical Scanning

PADT uses structured-light scanning to do non-destructive optical scanning of parts. This process uses a projected grid of light and two cameras to measure how the lines distort as the are projected on to the object. The software then uses the resulting image to calculate points on the object with very good accuracy and very little stray points.

The resulting data can be used to create a CAD model, make a polygon model for 3D Printing or simulation, or used for inspection purposes.

Much More than
Taking a Picture of the Part

3D optical scanning is a powerful tool when used correctly.  PADT's engineers are skilled users of our Zeiss scanning system and have been trained not only on how to use the device, but also on how to prepare a part, the best way to scan the part, and how to set the scanning parameters for the best outcome.  Once the actual scanning is done, the real work begins.

The scanner produces a cloud of point data that must be reviewed, cleaned, and converted into a solid image that can be used for inspection, assembly modeling, or prototyping.  PADT's engineers have a unique and useful set of skills in this area because of their background in Finite Element Analysis, rapid prototyping file (STL) creation and repair, as well as in general 3D modeling.  This allows them to really make sure that the data from the scanner is of the highest quality and of the most use.

The last step in the process is the most difficult and the one that requires the most engineering knowledge: converting that scanned data into a usable solid model.  Some customers do not need this; they simply need a faceted or point definition, but most users need that scan data converted into a usable solid model so that they can modify the geometry, use the geometry to design parts around it, or use it for manufacturing.  This is where PADT's extensive experience with the Geomagic software line comes into play.  Geomagic will convert the scanned data into a valid solid model, and our engineers’ decades of experience with 3D solid modeling are a win-win solution.
