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.

作为制造技术已经存在多年的金属形成。形成是指变形过程，通过添加引起材料流动的应力来影响材料的变形过程。增量形成（如果）是一个更现代的过程，在该过程中，在材料中进行小变形，一个特定的小变形序列会导致所需的形状。单点增量形成（SPIF）是一种高度灵活且具有成本效益的新钣金形成过程，用于有限的数量制造。 SPIF有可能对快速原型，低量生产和定制生产产生重大影响。由于缺乏对部分特定形成模具的需求以及在机械车间通常发现的设备，因此该过程非常适应。通过使用通用固定装置和形成工具，通过逐渐变形的材料来实现形成。
