A guide to sheet metal prototyping

A guide to sheet metal prototyping

Sheet metal is a thin metal sheets, cut, folded and then tapered to a specific edge and  from a single pattern. RP tests the metal for fatigue before it is cut or stamped for actual use. It is often a lighter and more affordable alternative to metal stamping. Sheet metal can be cut by lasers, CNC, water jet or punches. It is then folded so that the ends are aligned and then tacked, so the ends meet.

It is a low-cost option for prototyping and test runs. It has all the functionality of the finished product and is very easy to modify.

Sheet metal is typically cut by shears, water jet cutting, laser cutting, punch dies and CNC machining. CNC machining is most used early in the prototyping process. Once a design has been examined and modified as required, the product may be water jet cut or laser cut. At each stage of production, a more refined prototype may be made. Punch die stamping is typically the last process, since it provides the most accurate representation and is expensive. Sheet metal design requires a fair bit of dexterity and hand-eye coordination, which is why some people believe that the prototyping process is easier with CNC.


Sheet metal can be made from different types of metal, so it can be a very light-weight design.

Sheet metal is flexible, so it can be easily adapted to fit on other types of metal structures.

It can be folded to prototype parts that must be able to spin.


Sheet metal is thin and delicate, so it may not be the best option for all types of designs.

If it's not sealed properly, it can be difficult to maintain the integrity and strength of the metal.

This blog post will discuss the pros and cons of sheet metal prototyping. It will also provide readers with some of the reasons why this type of prototyping is beneficial. It will go into detail about whether or not it is a flexible option and weigh its disadvantages.
