D Scanners

D scanners include handheld, tripod-mounted desktop, and industrial automated units; choose based on object size, required accuracy, and workflow—handheld for medium-to-large objects and flexibility, desktop for small detailed parts, and industrial units for high throughput and repeatability

For general prototyping, look for 0.1–0.5 mm accuracy and sub-millimeter resolution; for metrology or inspection tasks, target scanners that specify accuracy in tens of microns (e.g., 0.01–0.05 mm) and support point spacing or mesh resolution appropriate to the smallest feature you must capture

Shiny, transparent, very dark, or highly reflective surfaces can cause noise and holes; matte, uniformly colored surfaces scan best—use temporary matte spray, a removable coating, or scan targets/markers to improve results when working with problematic materials

Check that the scanner supports common file formats (OBJ, STL, PLY), has drivers for your OS, and includes or works with software for alignment, cleaning, and exporting; also consider available plugins for CAD/inspection tools if you need reverse engineering or dimensional analysis

Follow the manufacturer's cleaning and storage recommendations, protect optics from dust and impacts, perform regular calibration using provided targets or procedures, and update firmware/software to ensure accurate measurements and compatibility

Entry-level or hobby-friendly D scanners typically start in the lower hundreds to around a thousand dollars for desktop units; prosumer handheld and higher-accuracy desktop models commonly range in the mid-hundreds to a few thousand, while industrial-grade scanners and complete automated systems are in the higher-thousand to tens-of-thousands range

Common accessories include turntables or tripods, calibration targets, mounting brackets, marker dots or stickers, matte spray for difficult surfaces, and spare power or connection cables; select accessories that match the scanner's workflow and object sizes you scan
