Sheet Metal Prototyping
Sheet metal forming describes the forming of thin sheets of metal by applying pressure through male or female dies or both. Parts formed of sheet metal have such varied parameters that it is sometimes complicated to categorize them. Sheet metal forming processes include laser cutting, waterjet cutting, roll forming, deep drawing, stretching, flanging, embossing and spinning. In nearly all of these procedures there are not any planned major changes in the thickness of the sheet metal. Sheet metal designs may feature welds and threads (depending on thickness.)
