Rapid prototypingRapid prototyping
• Communications tool• Additive or subtractive process• Growing parts introduced in 1987• Parts of any geometric complexity• Rapid tooling• VOC

Rapid prototypingRapid prototyping
• Additive not intended to replace all methods of part fabrication
• Limited material choices - additive• Parts will not be as durable• May require extensive secondary finishing
operations

Rapid prototypingRapid prototyping
• A six month delay in production start can result in a 66% loss in gm*
• 80% of costs of NPD before detailed drawings released*
• VOC – LEAN• Touch, feel, hold vs. 3D model
