CAD/CAM dentistry Like other CAD/CAM fields, CAD/CAM dentistry uses subtractive processes (such as CNC milling) and additive processes (such as 3D printing) to produce physical instances from 3D models.
WorkXPlore 3D PartXplore is a collaborative viewer for 2D and 3D CAD files.
3D computer graphics software Although 3D modeling and CAD software may perform 3D rendering as well (e.g. Autodesk 3ds Max or Blender), exclusive 3D rendering software also exists.
T-FLEX CAD T-FLEX CAD (T-FLEX) is a Parasolid-based parametric CAD software application for 3D solid modeling and 2D design and drafting, developed and sold by Russia-based software company Top Systems.
3D scanner Most applications, however, use instead polygonal 3D models, NURBS surface models, or editable feature-based CAD models (aka Solid models).
3D scanner 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 vivo" or "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 vivo" and produce the restoration (such as a Crown, Onlay, Inlay or Veneer).
Gable CAD Gable CAD was an advanced 2D and 3D design package with different modules, and was operated via a windows style interface and mouse running on UNIX. It was possible to create detailed 3D models and then generate 2D drawings or rendered visualisations from the data.
3D scanner 3D scanners are used to capture the 3D shape of a patient in orthotics and dentistry. It gradually supplants tedious plaster cast. CAD/CAM software are then used to design and manufacture the orthosis, prosthesis or dental implants.
3D printing 3D printable models may be created with a computer-aided design (CAD) package, via a 3D scanner, or by a plain digital camera and photogrammetry software. 3D printed models created with CAD result in reduced errors and can be corrected before printing, allowing verification in the design of the object before it is printed. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
WorkXPlore 3D PartXplore is a proprietary computer aided design (CAD) file viewer developed by Sescoi for reading, analyzing and sharing 3D and 2D CAD files without needing the original CAD application. It was launched in 2008 and is supported from local Vero offices. A viewer and an evaluation version are offered as freeware.
3D pose estimation This approach is appropriate for applications where a 3D CAD model of a known object (or object category) is available.
3D scanner Vendors offer different approaches to getting to the parametric CAD model. Some export the NURBS surfaces and leave it to the CAD designer to complete the model in CAD (e.g., Geomagic, Imageware, Rhino 3D). Others use the scan data to create an editable and verifiable feature based model that is imported into CAD with full feature tree intact, yielding a complete, native CAD model, capturing both shape and design intent (e.g. Geomagic, Rapidform). Still other CAD applications are robust enough to manipulate limited points or polygon models within the CAD environment (e.g., CATIA, AutoCAD, Revit).
3D modeling 3D models are widely used anywhere in 3D graphics and CAD. Actually, their use predates the widespread use of 3D graphics on personal computers. Many computer games used pre-rendered images of 3D models as sprites before computers could render them in real-time.
CAD/CAM in the footwear industry 3D CAD/CAM is the core technology for shoe sole mould in the footwear industry and develops towards specialization.
CAD Overlay The first version of CAD Overlay was demonstrated at A/E/C trade show in Chicago in May 1988. Subsequent versions include CAD Overlay ESP, CAD Overlay GSX, and CAD Overlay LFX.
3D ultrasound Conversion of the 3D image files into standard CAD/CAM file formats allows the reconstruction of fetal and other images in a variety of materials including a 3d laser etched images in a crystal glass block or a solid cameo effect using a 3D printer.
T-FLEX CAD T-FLEX CAD is interoperable with other 3D-modeling and 2D-drawing systems via the following file formats: Parasolid, IGES, STEP, Rhino, DWG, DXF, SolidWorks, Solid Edge, Autodesk Inventor, etc.
CAD/CAM dentistry As in other fields, additive manufacturing (3D printing) first entered CAD/CAM dentistry in the form of laboratory experiments, but its use has since expanded; and chairside use, although not yet widespread, is advancing.
3D pose estimation Another approach is to register a 3D CAD model over the photograph of a known object by optimizing a suitable distance measure with respect to the pose parameters.
3D pose estimation The distance measure is computed between the object in the photograph and the 3D CAD model projection at a given pose.
