Three-dimensional scanning has been widely adopted in industries including manufacturing, aerospace, and entertainment. Engineers, product designers, and researchers use 3D scanners to obtain 3D scan data which can allow them to construct 3D models or run inspections to determine deviations. Handheld 3D scanners are gaining more and more attention because of their portability, ease of operation, and quick results.
How can you choose a handheld 3D scanner to meet your needs? Here we share some tips to shed some light.
Factors to consider
Sizes of Objects
When choosing a scanner, you need to first think about the size of the object you want to scan. If you want to scan a small coin, a 3D scanner that can capture intricate details in high resolution would be a good choice. If you are planning to scan a large size object or part like a wind turbine, you need a long-range scanner with a larger field of view. It means that the scanner can capture a large area from a certain distance.
Accuracy
The accuracy of the scanning means the permissible deviation of each point captured. The accuracy of 3D scanners is largely within a range of 0.01 mm to 0.1 mm. A 3D scanner with an accuracy of 0.06-0.07 mm would be acceptable for most tasks. If you are planning to scan a complex industrial part such as an airplane engine, choose a 3D scanner with high accuracy.
Resolution
Resolution describes the minimum distance between captured points at a given scan distance. The higher the resolution, the denser the cloud of scan points. When the details of a 3D model are important to you, you would require a high resolution. If not, low-resolution requirements are suitable for you.
Scanning rate
When we talk about the scanning rate, we refer to how fast a 3D scanner can capture data off any given object. The rate varies depending on the number of laser lines, the size of the scanning area, and the algorithm of the equipment. A top-of-the-range handheld scanner can measure up to 2 million times per second.
