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