For most people, buying a 3D scanner is a new experience. Since each 3D scanning system has its own characteristics and uses different technologies (such as handheld laser 3D scanners, camera-type 3D scanners, 3D photogrammetry systems), there are currently 3D scanners on the market, which is suitable for you. ?
1. What is the budget for purchasing a 3D scanner?
Sometimes you need to sacrifice some features and find a workable solution to fit your budget. Sorting the function's primary and secondary is beneficial to your choice.
2. What is the object of the scan?
When purchasing a 3D scanner, identify the object you want to scan to determine which 3D scanner meets your needs. A scanner that is ideal for scanning human faces is not necessarily suitable for scanning structures. The more specific the range you want to scan, the easier it is to find a scanner that is suitable for your particular application.
3. What is the accuracy of the scanner?
Accuracy is the closeness between the actual value of the measured object and the theoretical value. Precision is usually defined as Z or precision. Since the X, Y accuracy is sometimes specified, the Z-precision value of the 3D scanner is of the utmost concern. Because the accuracy of the scanner directly affects the price of the 3D scanner.
4. Scan the size of the target?
Most scanners have a defined optimal scan range or scanned object size. Please note that you need to choose a different scanner depending on the size of the different scanned objects. For example, you need to use a different 3D scanner to scan a jewel and a car. Most 3D scanners have an optimal scanning distance of approximately one foot to two yards. The further this scan distance, the higher the price of the 3D scanner.
5. 3D scanner scanning speed requirements?
When scanning a stationary object, the scanning time will not be too long unless a large number of objects are scanned. For most people. A single scan time of less than one minute is acceptable. For scanning operators, a higher scanning speed is necessary because it is difficult to stand for a long time. You need to consider that the system takes time to process the scanned data, and a higher scan processing speed means a higher price.
6. What is the data scanned by the 3D scanner?
For most scanning projects, the first step is 3D data scanning. Scan data is often used for many purposes, or for CNC machining, or for visual effects, or for reverse design, 3D inspection. Different software uses different data formats. This will help you determine the features of the 3D scanner you need and complement other software that processes the data. After completing the 3D scan, you need to convert the scanned data or use it directly in the third-party software.
