With the use of a “Stratasys Objet Connex 350 Polyjet” 3D printer we have developed a method to produce a low cost rapid prototype for many of the keypad designs being proposed by our clients. The normal cost of this service is £200-£400 depending on size of the keypad and samples are usually available in 2 to 5 days.
With the wide variety of materials available to this system we are able to manufacture parts and assemblies made from multiple materials, with different mechanical properties, all in a single build. This allows us by combining materials in one assembly to provide a soft rubber like material in shore 40A to 95A hardness ratings and also add to this a hard plastic we can create hard key tops or even embedded graphics within the key surface. Combine this with a metal click dome and the client can get a more realistic impression of how their final product could look and feel.
Although the final result will not function electrically as a keypad, it does demonstrate how the keypad will look in the final assembly. If you are interested in this additional service from Diamond HMI please contact one of our Product Specialists on 01477 505206.
