3D Scanning in Reverse Engineering

By: Daniel McCarthy

3D scanning technology has vastly improved within the past decade making it more accessible and affordable for a number of various industries. By using three dimensional scanning, you will obtain fast and extremely accurate results that can be used for reverse engineering functions and inspection purposes. This technology has been an important part of the automotive industry for years, and now it has grown in its popularity in a number of other industries.
3D scanning utilizes laser light technology in order to create a digital model of the existing physical object. This information is then transferred into various software programs in order to create CAD models or triangle mesh models. These models can be analyzed for comparison purposes.
The process of 3D scanning generates a point cloud of data that represents the object's surface. The point cloud image can be used for analysis of the scanned object. This technology can be used to recreate existing objects, especially if the original design has been misplaced, such as a critical component of a bridge that may need to be replaced.
Modern technological advancements have given us a variety of scanning models. These scanners can accommodate a large variety of objects, from the smallest nail to a large bridge. Scanners can be classified as contact scanners and non-contact. You can select the appropriate type of scanner based upon the size of the object that you need to have scanned and the material composition of the object.
3D laser scanning is also ideal for objects that are composed of various materials that are delicate, which is why they are relied upon in the field of archaeology. By using reverse engineering, archaeologists are able to create reproductions of dinosaur fossils and other valuable artifacts for study and placement in museums.
The medical field has also taken advantage of 3D scanning. It is used in the field of dentistry for manufacturing dental implants and also in orthotics. The scanning technology has significantly improved orthitic devices by helping to make them as natural and fitted as possible.
Reverse engineering has been heavily relied upon by the manufacturing community. A number of manufacturers use this technology to guarantee that their products meet regulations before they are mass-produced.
3D scanning and reverse engineering technology continues to improve, increasing the number of useful applications that it has. As the design of scanning models has made them more portable and affordable, the number of useful applications of this technology will continue to grow.
