Rapid Prototyping / Tooling Checklist

Each of the following points has a unique impact on your available choices for a successful prototyping program.

Things to remember as you venture into Rapid Prototyping/Rapid Tooling:

• Part Geometry

  • Establishes the most appropriate process given the part configuration.
    
    

• Part Features

  • Which features can be cast and which will require secondary operations?
  • Can your choice of prototyping process support all features?
  • Can your choice of production processes support these features?
    
    

• Quantity

  • How many parts need to be produced?
  • Will the selected tooling options support this quantity?
  • Can the quantity needed be produced cost-effectively in the time available?
    
    

• Casting Process

  • What is the best casting option?
  • What Rapid Tooling options are compatible?
  • Is casting the best way to produce this part?
  • Do part configuration or quantity issues drive me toward a machined hog-out?  A "quick die"?
  • Does the casting facility understand my needs?
    
    

• Changes

  • What is the likelihood of changes after initial parts are produced?
  • Will my choice of process support changes?
  • Will the simple changes to part configuration force me to start over?
