What is 3D Scanning?
The standard file format used by 3D printers is STL which can be exported from all CAD packages and 3D Scanners. Where CAD files do not exist a 3D scanner can be used to capture the data which can be put back into CAD for further work, or printed via the 3D scanner.
3D scanners are also used to compare STL file data with print data for component assurance. The software that accompanies the hardware generates reports to support metrology applications.
Non-contact methods of scanning are implemented to attain the data. Using triangulated data from reflected laser light, distance information is captured. This is visualised in the form of data points, and large numbers of these are produced to simulate the shape (a point cloud).
Using the Point Cloud
The point cloud contains precise information of external part dimensions, to a tolerance of 0.3mm. Internal features, or areas hidden from the scanning laser, cannot be captured and this requires manual input through our Reverse Engineering service. However for most metrology or inspection services, exterior component surface information is all that’s needed.
The point cloud data can be sent to you in its native file type for you to use or modify as needed, or it can be ‘cleaned’ or reduced in size to be made more manageable.

Parts may need NDT spray applied to improve scan quality. This is washable and leaves no mark. Please state on any request if you do not want this process to be applied.
