Yes, a 3d scanner can scan an irregular shape, but how much the model will turn out right depends on the type of the scanner and the complexity of the shape. The MarketsandMarkets’ 2022 report projects the global 3d scanning market to reach USD 6.73 billion by 2027, while markets for manufacturing, healthcare, architecture, and other industries continue to develop. The growth in demand has been witnessed for 3D scanners that can operate on complicated, as well as irregular shapes, while industries seek more precision and efficiency in their operations.
3D Scanning Technology: This technology has evolved over time and now provides very detailed scans of objects with complicated geometries. For example, laser scanners, which function by sending out laser beams and calculating how long it takes for them to return, can capture millions of data points on irregular surfaces with great accuracy. A survey conducted by 3d Scanning International in the year 2021 showed that laser scanners are 30% more effective in capturing fine details on irregularly shaped objects than any other kind of 3D scanner, especially when used to scan intricate objects like sculptures or uneven terrains.
In the case of structured light scanners, the technology projects a series of light patterns onto an object, while a camera records the deformation of the pattern in order to create the 3d model. These kinds of scanners work particularly well in building smooth surfaces but can also handle some degree of irregularity. The structured light scanner, like the Revopoint POP 2 for example, with its resolution of 0.1 mm can scan objects as small as a coin or even as large as a full-size car, therefore versatile in scanning various shapes, including irregular ones.
Scanning very irregular shapes can, however, be challenging at times. According to 3d Scanning Expert Journal, highly reflective or transparent surfaces, like glass or shiny metal, can cause errors in the scans. These materials may require additional preparation, such as applying a special powder to dull the reflective surface, or more advanced techniques such as photogrammetry, which involves taking multiple photographs from different angles to reconstruct a 3d model. NASA famously used photogrammetry on the moon’s surface for their projects in lunar exploration, proving that even highly irregular terrains can be captured effectively using specialized techniques.
The time involved in scanning irregular shapes also differs: from mere minutes for small to medium-sized objects to hours for larger, more complex scans of historical artifacts or architectural features. The efficiency of the scanning process depends on the scanning resolution and the software used to process the data. A higher resolution scanner captures more data points and results in a more accurate representation, but it may also increase the time needed for scanning and post-processing.
The 3D scanner is very reliable for those wanting to get quality scans of any shape, especially an irregular shape. Because of advancements in technology, these types of scanners can now scan a wide variety of shapes and materials accurately, making them required tools in industries depending on the accuracy of results. From artwork to prototypes made by engineers or even complicated mechanical pieces, 3d scanner have indeed proved their worth in handling irregular geometries.
