3D scanning is revolutionizing measurement and design, bringing precision and versatility to engineering, architecture and industry. We discuss the 3D scanning process – from planning to analysis and practical use of the measurement results – to help you better understand how to effectively use this technology in a variety of applications.
What is 3D scanning?
3D scanning is the process of digitally mapping objects and surfaces. It enables the creation of precise 3D models with accuracy to fractions of a millimetre. Unlike traditional measurement methods, this technology allows for fast and non-invasive data acquisition. At PROram, we use scanning in, among other things, reverse engineering, where the exact geometry of components is required.
3D scanning in industry is used for quality control and technical inspection. It facilitates the detection of deviations in structures or production processes. Architects use the technology to document and renovate historic buildings. Engineers use scanners to analyse and optimize designs in CAD systems. The popularity of this technology is growing steadily, and its precision and versatility are opening up new opportunities in various industries.
The 3D models generated by the scanning process are also the basis for virtual reality technology. They also support the creation of digital twins used in analysis and simulation.
How do you plan the 3D scanning process?
Planning 3D scanning requires a precise definition of the target and scope of the measurements. It is important to select the type of scanner according to the characteristics of the object and the requirements of the project. Laser scanners work well for both large surfaces and precision industrial applications. In the case of components with complex geometries, it is also important to plan multiple scanning perspectives. Therefore, the selection of the right equipment and its quality are particularly important for the final results of the process.
The first step is to prepare the object. The surface must be clean and properly protected to ensure data accuracy. For reflective elements, special coatings or markers may be necessary. For more complex projects, pre-tests are important. These help to assess equipment settings and potential difficulties.
The planning stage also includes the selection of suitable software for data processing. Professional preparation reduces implementation time and minimises the risk of errors in the scanning process.
How does the 3D scanning process proceed step by step?
The 3D scanning process begins with object preparation and equipment configuration. For larger structures, it is important to plan the optimal reference points. The operator calibrates the scanner, adjusting the settings to the project requirements and environmental conditions. This is an important step, as correct settings affect the precision and quality of the data.
The scanner creates a point cloud, representing the geometry of the object in digital format. For more complex objects, it is necessary to scan from different perspectives. We integrate the acquired data into a single model using specialized software.
The point cloud can be used to create CAD models or other digital formats. During processing, noise and errors resulting from imperfect measurements are removed. The final model is the basis for further analysis, production or design. The whole process requires precision and experience. It is not enough to buy an expensive scanner to achieve good results.
What to do after scanning?
The first step is to clean the data of any noise or errors that may arise during the measurements.
The finished point cloud is transformed into a digital 3D model. Such a model is the basis for analysis, design or visualisation. CAD/BIM software allows additional information to be added, such as material properties or operating conditions. Adjustments can also be made at this stage, such as removing minor defects or filling in missing data. The processing process ends with the creation of a digital model, ready for further use.
Data analysis also allows the 3D model to be compared with technical documentation or other standards. This is an important step in quality control, where every deviation can be located and described. In reverse engineering, we use the data to reconstruct missing technical documentation. In production, 3D models can be directly exported to numerically controlled equipment.
Examples of measurements carried out by PROram
- Welding quality control on the Valhall Field offshore project
This is one of PROram’s prestigious contracts and proof of the highest quality of our services. Our welding inspectors are working on the steel structures used to build offshore platforms at the Valhall field in Norway. There is no room for compromise here. The project requires the highest quality and accuracy of welds. That is why we use 3D laser scanners for real-time NDT testing. Find out more about the project.
- For our client Protolan, we performed scanning of a large-scale warehouse in Zabrze.
The project started with a thorough analysis of the client’s needs, followed by the scanning of the hall with LEICA portable scanners . Subsequent stages included data processing in advanced CAD/BIM software, creation of a BIM model and its verification. These processes provided Protolan with a complete digital documentation that provides a solid basis for further design. Explore project details.
- Air Products encountered a problem with the inaccurate coaxiality of the rollers of their flanged pipe welding machine.
We prepared and carried out industrial measurements using a 3D laser tracer. The test results allowed us to correct the machine settings and achieve design concentricity and thus increase the welding quality. Find out more about the project.
- Laser scanning and NDT analysis of the KOMATSU crusher shaft
Komatsu Poland faced the challenge of locating the cause of the crusher shaft failure. With the measurement and analysis service of the results, PROram engineers, were able to quickly identify the problem, while minimising the time and costs associated with conventional inspection methods. In the case of Komatsu, the use of 3D scanning technology contributed to an accurate diagnosis of the problem in just one day! Find out the details of the project.
