Solid Freeform Fabrication
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Solid freeform fabrication (SFF) is a collection of techniques for manufacturing solid objects by the sequential delivery of energy and/or material to specified points in space to produce that solid. SFF is sometimes referred to as rapid prototyping, rapid manufacturing, layered manufacturing, additive fabrication and additive manufacturing. Sheets of paper or plastic film are attached to previous layers by either sprayed glue, heating, or embedded adhesive, and then the desired outline of the layer is cut by laser or knife. Finished product typically looks and acts like wood.
