A 3d scanner is a machine that digitizes an object, using laser, structured light or photogrammetry to measure the shape and appearance of surfaces. These scanners capture data in the form of point clouds that are then processed into accurate 3D models. Depending on the device and application, the resolution of a 3d scanner is usually about 0.1 mm to 0.5 mm or so.
3d scanners differ greatly in scanning speed, and modern handheld devices like the Artec Eva FX are capable of scanning up to 2 million points per second, so they can be extremely valuable for industrial applications. Some 3d scanners such as revopoint are also more portable with weights less than 1kg to help professionals perform these scans in the field. They are compact enough to capture objects that range from 10 cm to 4 m, and can be used in industries from engineering through to healthcare.
In sectors like manufacturing where reverse engineering is applicable, the accuracy of 3D models make 3d scanning instrumental. Rather, 3d scanners are used by automotive companies to measure parts with tolerances as tight as 0.01 mm. In addition to performing inspections, these devices assist with quality control because they detect deviations in intricate geometries quickly.
3d scanners are now much less expensive. They can vary in price from just over $500 for entry-level models to more than $50,000 for high-end industrial-grade devices. It is in such a price range to make 3d scanning available for many small businesses and hobbyists. In 2021, the global 3d scanning market was valued at USD 3.7 billion and is projected to grow at 19% CAGR due to digitization in design and manufacturing processes
To quote the famous futurist Ray Kurzweil, “The future is already here — it’s just not very well distributed.” His point of view reflects on how today’s devices such as the 3d scanners changes workflows, specifically where both real and digital objects meet. In healthcare, for example, 3d scanners can map patient anatomy and reduce the lead time for custom prosthetics by up to half.
A 3d scanner can be used in a number of industrial applications, but its uses do not end there. These tools are used by artists and architects to commission a Preservation of artifacts or an Immersive Virtual Environment Experience. 3d scanner also keep creating the future by digitizing objects with utmost precision and efficient methods.
