Portable 3D scanners capture real-world objects and convert them into digital 3D models. These handheld devices use structured light or photogrammetry technology to measure surfaces with millimetre precision.
Professional models offer accuracy rates from 0.1mm to 0.5mm. Entry-level scanners work well for hobbyists and small projects. Most connect via USB and work with Windows and Mac computers.
Popular applications include reverse engineering, quality control, archaeology, and 3D printing preparation. Scanning speeds range from 30 seconds to several minutes depending on object size and detail requirements.
Key features include automatic meshing, colour capture, and export formats like STL and OBJ for CAD software compatibility.
