Advanced 3D printing technologies yield models that can serve as product prototypes. There has been large growth in the sale of 3D printers. Additionally, the cost of 3D printers has declined. The technology also finds use in the jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, GIS, civil engineers, etc.
