Stereolithography (SLA), Selective Laser Sintering (SLS) and Fused Deposition modeling (FDM) are methods for making presentation quality prototypes very quickly, accurately and relatively inexpensively.  

This process allows new product developers to make one or two presentation models of a new product before going to the expense of building plastic injection molds, forming dies or castings.  This way you can test the market before committing to hard tooling..  It also allows you to put "works like/looks like" models in the hands of focus groups for final pre-production evaluations.

We highly recommend this process before building the actual injection molds.  Here are some helpful links to information resources and companies providing these services around the country.

TIP:
If you are planning to sell your product to a large company or major player in a specific market, you will want as much protection as you can get. In other words, one or more Utility patent(s), design patent(s), trademark(s), copyright(s) and trade secret(s).
