It is an understood fact that the whole reason for prototyping is to ensure the best possible part design before committing to the cost of building permanent tooling. Design changes in the prototyping phase of product development can be a normal part of the process.
On average 25% to 30% of prototypes result in design changes. For this reason it is important for you to know what kind of changes the prototyper can handle and the approximate cost to make changes to the original prototype tool. In the final analysis the prototype process you choose can greatly affect the cost of design changes during prototyping.
In some prototyping processes if you have to make design changes after initial parts have been produced you might have to start all over again with brand new tooling to effect the changes. Aluma Cast uses rigid tooling that in addition to being more dimensionally stable than some softer materials, also allows for quick and economic design changes.
