3Sourceful is a market for connecting small scale designers to small scale manufacturers. It is a technical site, but for creative entrepreneurs.
To give you an idea of the use of the site consider the following example: when a new product gets funded on kickstarter, they often need to make 100's or a few 1000's of a parts. A designer or inventor cannot make this many themselves. However, they do not need enough to outsource production. 3sourceful is a market to connect these types of entrepreneurs to manufacturers.
The primary technology used will be 3D printing, which is becoming very popular in use and in the press. Similar companies in this space include MakerBot, Shapeways, Ponoko, and iMaterialise. Of these companies, MakerBot has the logo that is similar in look, feel, and target audience.
We need to connect to people that are in the following groups:
'makers' - people who are technical and have a do-it-yourself attitude. These are builders, experimenters, and tinkerers. Some images here could include hammers/anvils/robots/gears/etc.
'techies'- the people using this service will be using digital design to design shapes and computer design files. They are very tech savvy. The can use CAD and other technical packages. Images here could include 3D perspectives/clouds for cloud computing/interesting geometries/bits and bytes.
