While 3D printing gets a lot of attention on the output side of the design process, going from digital to physical; just as important is the converse, going physical to digital, also known as 3D scanning. Like 3D printers, 3D scanners vary in object capture quality (resolution), and associated cost — ranging from a few hundred to tens of thousands of dollars. 3D scanners are also being used for a growing number of applications, including big-ticket industries, such as automotive and aerospace.
The automotive industry has been particularly fertile ground for 3D scanning with applications ranging from reverse engineering to inspection. I recently came across an interesting automotive 3D scanning application using Artec scanners.
