3D scanning is a process of structuring the form of a physical object and converting it into a digital model. To prepare, the object should be clean and in good lighting conditions. In the case of reflective or transparent surfaces, there is a possibility to improve the scanning accuracy by applying matte spray. Using portable 3D scanners-like the Revopoint POP 3 Plus-allows for the accommodation of objects from 20 mm to 2 meters in size, thus offering more versatility for a wide range of applications.
The distance between the scanner and the object should be kept the same during scanning. Most handheld scanners work optimally in the range of 200 mm to 500 mm. Moving the scanner slowly around the object, it captures all the data and creates a dense point cloud. Objects as small as a figurine take around 5 minutes to scan, while larger objects take up to 30 minutes, depending on their complexity.
Afterwards, with the use of software like Revo Scan or MeshLab, the captured data is processed. Cleaning of the point cloud, filling gaps, and conversion of data into a polygonal mesh are done. The result is detailed, as high-resolution scanners can achieve accuracy up to 0.1 mm. The resulting file is exported in a format like OBJ or STL, readable for most modeling programs such as Blender, Maya, or ZBrush.
The scanned data serves as a base for digital enhancements or modifications. Designers use these models for tasks like animation, rendering, or 3D printing. For instance, a product designer might scan an existing part to create a custom-fit prototype, reducing development costs by 30%. In another example, game developers use 3d scanners to create realistic assets, cutting production time significantly.
A sculptor from France said, “3D scanning has transformed the way I work. I can quickly digitize my clay models and refine them digitally, saving me weeks of effort.” Such feelings are reflected across industries like healthcare, where surgeons use scanned models to plan complex procedures, and architecture, where digital models streamline construction planning.
The modern 3d scanners, costing in the range of $500 to $2,000, are well within the reach of professionals and hobbyists. Devices like the Revopoint POP 3 Plus combine great performance with portability and ease of use. Visit 3d scanner for 3d modeling for more.
