Having already discussed what is LiDAR and 3D Models with Drones. This article will cover 3D Scanning by answering the following questions: What are the uses for Point Clouds and Mesh? and What industries can benefit from 3D Scanning? Keep reading to learn all about 3D technology to #ONEUPYOURBUSINESS!


Point Clouds are created by scanning objects or structures, either using a laser scanner (also known as LiDAR) or drones.

As their name suggests, Point Clouds are millions of data points containing information about the scanned objects. Their primary use is data analysis. When more visual representations are required, Point Clouds are processed into Mesh, a continuous surface at the expense of losing the vast majority of data.

The three-dimensional models help a range of industry sectors (Construction, Property, Facilities Management, etc.) as they can help preserve historic landmarks and listed buildings, create fully interactive Digital Twins, and so on. You can read the total use cases by heading over to our 3D Models with drones to read more.


As the 3D technology can provide precision, accuracy, and versatility, 3D Scanning is beneficial for multiple industries, and below, we provide a list:

  • Healthcare: The technology can take accurate measurements quickly and effectively, so for instance, if a patient needs a prosthetic limb to be created then 3D scanning, then the patient can be scanned without them having to spend ages getting measurements taken and due to the accuracy, the patient can obtain a replica of a limb, all whilst saving time and money
  • Archaeology and palaeontology: When it comes to examining and studying fragile historical artefacts as an example, 3D scanning can make it possible for people to interact with the artefacts virtually and is used to create 3D models of fossils and is beneficial for preservations of precious historical artefacts
  • Quality Control: Combing Artificial Intelligence (AI) with 3D technology is powerful as it can teach computers to create decisions making automated quality control, reducing human error and work hours. An example, the two technologies can identity and inspect a dent in a vehicle or object, measure impressions and take immediate action if required
    Manufacturing: 3D Scanning can create CAD files in the design stage of a project. 3D models can also be used to improve design accuracy. Obtaining correct measurements and CAD files ultimately
  • Local authorities and planners: With net-zero on top of the agenda to make a greener economy, the planning process is essential in supporting the sustainable growth of the urban environment. 3D maps can provide local authorities and planners with a realistic view of a location, helping them to visualise, view, and plan projects
  • Construction: 3D maps can help the construction sector, as they can be used as a blueprint on sites where construction will take place. Workers will have access to floor plans etc., which can also identify if there are any obstructions or concerns that may occur during construction etc., helping them to work more effectively and efficiently
