Sheet metal forming has existed for many years as a manufacturing technique; forming refers to the deformation process through which a material is shaped by the addition of stresses causing the material to flow plastically. Incremental forming (IF) is a more modern process where small deformations are made in the material, a specific sequence of small deformations result in the desired shape. Single Point Incremental Forming (SPIF) is a highly flexible and cost effective new sheet metal forming process for limited quantity manufacturing. SPIF has the potential to have a significant impact on rapid prototyping, low quantity production and customized production. The process is extremely adaptable due to the lack of need for part specific forming dies and the use of equipment that is commonly found in machine shops. Forming is achieved by incrementally deforming material with the use of a generic fixture and forming tools.

金属板成形作为一种制造技术已经存在了很多年;成形是指通过增加应力使材料塑性流动而使材料成形的变形过程。增量成形（IF）是一种更现代的工艺，其中在材料中进行小变形，特定顺序的小变形导致所需的形状。单点渐进成形（SPIF）是一种高柔性、低成本的金属板材成形新工艺。SPIF有可能对快速成型、小批量生产和定制生产产生重大影响。由于不需要特定的成型模具和使用机械车间常见的设备，该工艺具有极强的适应性。成形是通过使用通用夹具和成形工具使材料逐渐变形来实现的。
