3D Scanning Services

RASCO is an experienced team with 15 years experience in 3D Scanning and is equipped with the world's best equipment. 3D Scanning is done by either light based technique (Structured Light Scanning) or by Laser. We are equipped with both the technologies. Each technology has its benefits and is suitable to a particular operation.


Structured Light Scanning

Structured Light Scanning is the technique of capturing geometry via non-contact imaging. Structured light scanners use cameras to capture behaviour of fringe patterns projected on an object via a projector. The source of light, i.e. the projector technology, determines the type of scanner, whether Blue Light (usually LED Technology) or White Light (LED or DLP technology). Structured light technology is good where the quality and resolution of Data is very critical. These are flexible machines which can be calibrated for speed and resolution depending on application. Being flexible, with these machines there is no limit to the size of the component which can be scanned. Structured Light Scanners produce data accuracy anywhere between +/-0.010mm - +/-0.080mm depending on scanned object size and calibration results. However, these accuracy values are manufacturer's claims and not backed by any third party inspection bodies. Although this method is very lengthy for scanning and usually requires spraying the parts it is more suitable for reverse engineering where the resolution and depth of data is more important than accuracy. 


We are equipped with the following Structured Light Scanners:


- HDI Advance R1x - 1.3MP White Light Scanner with DLP Technology

- HDI Advance R3x - 2.8MP White Light Scanner with DLP Technology

- HDI Carbon Pro - 5MP White Light Scanner with LED Technology

- Geomagic Capture - 1.3MP Blue Light Scanner with LED Technology 


Laser Scanning

LaserScanning is the technique of capturing geometry via non-contact method by running a 2D Laser via a LLP (Laser Line Probe) over an object. The LLP is mounted on a 7-Axis Arm, which controls the movement and position of the Scanner. Laser scanning is beneficial where the object cannot be sprayed in white colour spray and no markers are required. However, the size of the component which can be scanned is dependent on the size of the Arm on which the LLP is mounted. This technology comes with certified accuracy delivering anywhere between +/-0.008mm - +/-0.075mm. Since this technology requires no part preparation before scanning (hence non destructive method) and has certified accuracy, it is more suited towards Quality Inspection jobs. 

We are equipped with the following Laser Scanner:


- FARO Design ScanArm 2.5C - 2.5Metres 

This arm is equipped with the FARO Prizm Colour Scanner enabling colour capture which can be used for animation, computer graphics and 3D product design studies.
