initial research into 3d modeling/printing – Wikipedia

  • 3D scanningis the process of analysing a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colour). The collected data can then be used to construct digital 3D models.
  • 3D scannercan be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitisedare still present. For example, optical technology may encounter many difficulties with shiny, reflective or transparent objects. For example, industrial computed tomography scanning and structured-light 3D scanners can be used to construct digital 3D models, without destructive testing.
  • Collected 3D data is useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality. Other common applications of this technology include augmented reality,[1]motion capture,[2][3]gesture recognition,[4] robotic mapping,[5] industrial designorthotics and prosthetics,[6] reverse engineering and prototypingquality control/inspection and the digitization of cultural artifacts.[7]
  • 3D scanners are used to capture the 3D shape of a patient in orthoticsand dentistry. It gradually supplants tedious plaster cast. CAD/CAM software are then used to design and manufacture the orthosisprosthesisor dental implants.
  • Many Chairside dental CAD/CAM systems and Dental Laboratory CAD/CAM systems use 3D Scanner technologies to capture the 3D surface of a dental preparation (either in vivoor in vitro), in order to produce a restoration digitally using CAD software and ultimately produce the final restoration using a CAM technology (such as a CNC milling machine, or 3D printer). The chairside systems are designed to facilitate the 3D scanning of a preparation in vivoand produce the restoration (such as a Crown, Onlay, Inlay or Veneer).
