There are many different prototypes, with many different purposes. We build prototypes to fit each of those purposes, whether you need something quick for proof of concept, you need something that looks like a finished product but isn't fully engineered, you need something functional but not aesthetic, or you need a like production like prototype that look and functions like it would in production.
We provide mechanical engineering services to create the internal workings of your product, use FEA to make sure that what we are designing handles the stresses, and can be produced most efficiently through different manufacturing operations.
User testing is such an essential part of the development process. This is how you reduce risk and ensure that the product you are designing is effective at solving the problem of your customers. In many cases, this will be iterative with development to continue to improve and test the product until you are ready to start selling!
