260. Rapid prototyping applications functional

One of the more common applications for rapid prototyping is functional testing. Customers want parts that can closely mimic and function just like the "real thing" and to assist in the evaluation of fit, form and mechanical performance. The materials most commonly used for functional prototypes are the SLS DuraForm PA and DuraForm GF rapid prototyping thermoplastics. Other SLS rapid prototyping powders such as Somos 201, FR85A and LaserForm A also produce parts that are capable of serving as functional prototypes.

Patterns are utilized in the production of castings and short-run tooling. For investment casting of a metal part or parts, the SLS CastForm? PS patterns are considered more "foundry friendly" than SLA Quickcast?. This is because CastForm patterns can be autoclaved and easily burned out, as they are organic in composition, low in ash content and less likely to break the surrounding shells causing loss of production, time and money. SLA QuickCast? can produce larger patterns with slightly better detail and surface finishing, but the QuickCast patterns require more experience and special processing to cast successfully in the foundry, thus there are far fewer investment casting foundries willing to work with this rapid prototyping pattern material.

Patterns are also used to make short-run tooling, know as RTV or silicone molds for urethane casting and composite tooling for injection molding. For these processes, which are typically used to create a mold for the production of 10-1000 parts, SLA is usually the best process for making pattern masters.

Our rapid prototyping technologies allow you to save time and money by decreasing your time-to-market, and avoiding costly modifications to production tooling. Multiple versions of prototypes can be produced (iterated) and evaluated in days, versus weeks, allowing you time to refine your designs. In short, we can save you time and money, while helping you reach your desired goals.
