The use of 3D scanners is widespread among companies that make a large range of precision parts. A 3D scanner is a highly accurate measuring device, making it perfect for jobs that have a low tolerance for error.
Specifically, 3D scanners use laser technology to sample or scan a surface. There are various ways these scanners can be utilized, with the main difference being the amount of power used. When the surface of a part or object has only to be digitized, a 3D scanner will be set for low power.
3D scanners allow technicians to uncover information about a scanned surface.
3D scanners are versatile and programmable, allowing technicians to perform a number of delicate precision measuring tasks.
Among various 3D scanners on the market are very high-accuracy instruments that perfectly measure a three-dimensional shape. This use of 3D scanners is common in the casting and sheet metal stamping industries. Another type of 3D scanner is used when its necessary to measure three-dimensional shapes of plastic parts, press-formed parts and cast parts.
There are 3D scanners that use a technology known as laser beam light-sectioning. Here, technicians scan parts and other work pieces with a slit beam. A CCD (charge-coupled device) camera collects the light that is reflected from the part, then distance information is created from the 3D data by a process called triangulation. This gathering of information would be impossible without 3D scanners.
A use for high-precision 3D scanners includes dimensional measurement of dies, forging, sheet metal, casting and the production of molded plastic parts. In the precision parts industry, workers typically are engaged in making work pieces that must adhere to strict manufacturing guidelines. 3D scanners give them the required accuracy.
Adherence to exacting guidelines is critical, because parts and pieces that are off-spec can cause injury or worse to those who end up using them. A 3D scanner uses advanced technology to tell the devices operators much important data about the piece being worked on and assures that the piece will be finished correctly.
To sum up, high-accuracy, portable 3D scanners are ideal technology for any precision work that calls for dimensional analysis, reverse engineering and industrial design. 3D scanners are also excellent research and development tools.
