Summary
Rapid prototyping is a manufacturing method that creates three-dimensional objects. Students learn how it developed, its main processes and some of its uses.
History of rapid prototyping
Rapid prototyping began in the 1960s with Herbert Voelcker's work on solid modeling. Carl Deckard later developed selective laser sintering, building objects layer by layer.
Three major groups of processes
Subtractive processes remove material to create an object. Additive processes build an object layer by layer. Virtual processes create digital models.
Rapid tooling uses
Rapid tooling creates molds and dies using rapid prototyping parts. Vacuum casting is one method. It uses a rapid prototyping pattern to make a mold.
Rapid prototyping methods
Ballistic particle manufacturing uses inkjet technology to deposit materials. Laminated-object manufacturing bonds layers of adhesive-coated sheet material.
