Introduction to Rapid Prototyping
Purpose of Prototyping
Four Uses of Prototype
Communication
Integration
Learning
Milestone
Difference between Prototype and Actual Product
Not made from actual material but soft material
Does not have all the features in the actual product
Shaped close to actual product but not economical
More cost efficient compared to use for testing
Global Product Development
1) Customer Needs Survey
2) Product Definition
3) Idea Conceptualization
4) Select Concept
5) Detailed Drawing
6) Prototyping
7) Testing/Validation
8) Manufacturing
9) Marketing
CAD Data Exchange Format
IGES (Initial Graphics Exchange Specification)
STEP (International standard for product data exchange)
STL (STereoLithography)
AMF (Additive Manufacturing File)
Types of Prototype
Focus
Analytical
Physical
Comprehensive
Planning for prototyping
Step 2
Establish level of Approximation of the Prototype
How close should it be to the actual product
Physical or Analytical
Step 3
Outline an Experimental Plan
prototyping is experimental
ensure enough data is collected
plan the experiment
Step 1
Define Purpose of the prototype
Step 4
Create a Schedule
treat prototype as a sub-project
apply project management skill
