A 3D scanner — a laser, light or other sensor based device that captures the three-dimensional shape of a physical object. This scanner earns from shining a beam of light on the surface of the object, threading it and back to the scanner. The captured data is then processed and converted into a 3D file, which can be viewed, manipulated or printed out. Now it can analyze tiny details of 3D scanning with an accuracy of heating up to 0.1 millimeters depending on type and model.
3D scanning is a game changer for traditional sectors like manufacturing, healthcare and engineering. In the automotive sector, some examples include Ford & Tesla where 3D technology is combined into the production line with the capability to produce mould-accurate prototypes and high-quality manufacturing standards. 3D scanners are used in the medical field to develop specific prosthetics for individuals, offering a more comfortable and functional option. A report taken from “Medical Design & Outsourcing” highlights that the global healthcare 3D scanning market is projected to grow at a CAGR of 13.6% and will reach US$4.8 billion by 2027.
There are different types of 3D scanning technologies, including laser scanning, structured light scanning and photogrammetry. Laser scanners, for instance, emit a laser beam that travels across the object’s surface. In structured light scanning, some patterns of light are projected onto the object and will then be captured through cameras to produce a 3D model. Alternative photogrammetry uses a series of photographs to create the 3D data, typically used for things like landscapes or architectural models where there is a lot of larger scale data to scan.
In reverse engineering as well, 3D scanners are important for using them. And while it might save you time and money if you ever break your phone, that’s not the really interesting use for this technology: Companies such as General Electric utilize these scanners to create replacements for obsolete or hard-to-manufacture components. Reverse engineering actually makes up a large percentage of how 3D scanners are used in industries like aerospace and machinery repair.
There are several types of 3D scanners, each of which varies widely depending on their capability and, therefore, price. Low-end handheld scanners are usually in the $500-$2,000 range while high-precision industrial-grade scanners can exceed $100,000. Nonetheless, rising demand for 3D scanning technology in both consumer and professional markets resulted in rapid advances making them lower-cost solutions easier to access.
When it comes to practical applications, 3D scanning allows for rapid prototyping which can cut product development time by 50% or more. Fast prototyping of physical objects into a digital version enables rapid testing, changes and iterations to get products ready faster than before. 3D Scanners in ElectronicsIndustryExample: 3D scanners are used by electronic companies to make sure that the different parts will fit with one another before commencing mass production.
Industries finally adopting the technology is also no surprise as 3D scanning continues to change industries requiring high levels of detail. As one example, in architecture, where 3D scanners will allow architects to measure the size of a building — which is useful for renovations and restorations. In historic preservation too, 3D scanning is utilized to digitally catalogue artifacts and monuments for posterity.
