If you anticipate your product will be made from plastic, there's a great product out there
that's ideal for creating plastic prototypes. It's called Shapelock. When heated in the
microwave or with your hair dryer, it becomes pliable, kind of like clay, so you can mold
it any way you'd like. When dry, it becomes a hard plastic. The best part? It's
inexpensive, and you can reheat it and reuse it again and again. Find it at

Of course, your product could also be made from any number of materials, ranging from
metals to chemicals to textiles. When using any material, try to be open to alternatives
you may not have originally considered. For example, you may be convinced that you
want to use cotton. If this is the case, challenge yourself by asking "Why?" Perhaps
another material might work better, such as a stretch material like Lycra. Or how about
using mesh, canvas, nylon or leather? What about taking a leap and trying Neoprene?
This is the time to say "What if" and allow yourself the freedom to explore. Put aside
your original thoughts--you may end up coming back to them, but at least then you'll
know you've made the best decision.

Once you've developed your prototype as far as you reasonably can, it's time to consider
hiring a professional to help you with the next steps. There are many avenues you can
take at this stage. You may wish to hire professional prototype developers, engineers and
designers, but others may be able to help you as well, including a handyman, a machinist
or a student from a local industrial design college. The complexity and materials to be
used in your specific product will help drive this decision. Your budget may also be a
consideration--a handyman or machinist, for example, will probably charge much less per
hour than an engineer, and their services may be perfectly sufficient if your design is
relatively straightforward.

If you do decide to go with a professional prototype developer, there are a few ways to
find them. You could try the Yellow Pages first, or you could try searching on (formerly known as, a one-stop resource
with all the information you need. It offers a database of 650,000 manufacturers,
distributors and service providers--including prototype developers--to choose from,
broken down by state. In a matter of minutes, you can find the expertise you're looking

You should also do your research and consider new and emerging technologies. For
example, there's a relatively new method of prototype production out there called rapid
prototyping, which uses a technology called stereolithography. It enables you to have
plastic prototypes made quickly from computer-aided drawings (CAD) by a large tooling
machine, rather than from an expensive injection mold. Rapid prototypes can cost as little
as a few hundred dollars each (depending on complexity), but they're often a bargain
considering the alternatives. For example, creating an injection mold for a product in the
Unites States can cost anywhere from $10,000 to $100,000.
The prototyping stage is a great time to use all your untapped creative ability and to
explore all the possibilities that are on the market. Don't limit yourself to any
preconceived notions--whether it comes to material use or the types of professionals you
can consult--and explore as much as you can as you begin bringing your product idea to
