3D Scanning – what is it?

3D scanning is an efficient, fast and accurate process of gaining data of the measurements of a physical object. Physical Digital® uses the top-of-the-range industrial 3D scanners produced by the German measurement experts GOM. With these systems, Physical Digital offers a fast, accurate, repeatable method for 3D scanning items ranging in size between 5mm and 20metres.

From small-scale components to cars, boats or aircraft, 3D scanning provides efficient and accurate measurement

We provide a fully mobile service where required, so your component or item stays at your site and we will come to carry out the measurement at your facility. This means that your production processes are not interrupted. Also, for portable parts, we have the capability to scan components at our own sites in Surrey or the West Midlands.

Alternatively, for a batch of components up to 2m in size, we offer measurement and inspection using GOM's high resolution industrial 3D scanners. Using our automated 3D scanning cell, the ScanBox, we provide a robotised measurement service in our specialist facility based in the Midlands. There are additional cost and time benefits of automated 3D scanning: using specially-designed fixtures we are able to carry out 3D scanning on a number of components simultaneously.

3D scanning – how does it work?

3D scanning using the GOM ATOS TRITOP scanning systems involves preparing the item by making sure it is clean and placing a series of coded and uncoded markers on and around the object to be scanned.

Twin cameras within the 3D scanning system capture high density surface measurements from a fringe projection of blue light which is cast onto the object for scanning. Using specialist software, the 3D data is then quickly processed into a triangle mesh or STL file.

3D scanning – what is it used for?

The industrial 3D scanners utilised by Physical Digital provide fast, accurate and repeatable results for a wide range of applications. We have an expert in-house design team which offers reverse engineering, which is the process of creating a computer aided design (CAD) model from scan data of the object. Reverse engineering is particularly useful for design modification, analysis and when the original drawings or 3D model has been lost or is non-existent.

The benefits of using high speed industrial 3D scanners is to provide accurate, reliable and traceable data are now widely recognised. 3D scanning is coming to be used as an industry standard within a broad spectrum of sectors including aerospace, automotive, research and development, tool making, product design, manufacturing and medical, as well as providing 3D scan data for 3D printing.
