4. Prototyping
A process of developing an approximation of the
product along one or more dimensions of interest
Purposes of Using Prototypes
• Learning: Will it work?
• Communication: Look&Feel
• Integration: Components work together
• Milestones: Achievement
5. •The degree to which they are physical
• Physical Prototypes
• Analytical Prototypes
• The degree to which they implement the
products’ attributes
• Comprehensive Prototypes
• Focused Prototypes

Appropriateness of Different Types of Prototypes for
Different Purposes
8. Principles of Prototyping
• Analytical prototypes are generally more flexible
than physical prototypes
• Physical prototypes are required to detect
unanticipated phenomena
• A prototype may reduce the risk of costly iterations
• A prototype may expedite other development steps
• A prototype may restructure task dependencies
9. Planning for Prototypes
1. Define the purpose of the prototype
2. Establish the level of approximation
of the prototype
3. Outline the experimental plan
4. Create a schedule for procurement,
construction, and test
12. What is Additive Manufacturing?
• Additive Manufacturing is a method in which the part is created
by a layer- additive process.
• Using a specialized software, a 3-D CAD model is cut into very
thin layers or cross-sections.
• Then, depending on the specific method used (sintering, fused
deposition, etc), the AM machine constructs the part layer by
layer until a solid replica of the CAD model is generated.
• The advantages of this process is clear: development of
physical models can be accomplished in significantly less time
as compared to the machining process.

13. Commonly Used Terms for Additive Manufacturing
• Rapid Prototyping (RP)
• Direct CAD Manufacturing
• Desktop Manufacturing
• Instant Manufacturing
• CAD Oriented Manufacturing
• Layer Manufacturing
• Material Deposit Manufacturing
• Material Addition Manufacturing
• Solid Freeforming
14. Why Rapid Prototyping?
Machining is a subtractive process, beginning with a solid piece
of stock. The machinist must carefully remove material until the
desired geometry is achieved. For complex part geometries,
this is an exhaustive, time consuming, and expensive process.
Some parts are even too complex to be machined.

17. Create a CAD model of the design
Convert the CAD model to
STL format
Slice the STL file into layers
Construct the physical model
layer by layer
Clean and finish the model
Basic Steps of AM Processes
Computed Tomography
Scan
• RP requires a closed
volume of the model
• What you see may
not be what you get
The tessellated model
18. Advantages of AM
• Reduce product development time and cost
• Get products to market sooner
• Enhance communications between marketing,
engineering, manufacturing, and purchasing
• Present physical model at critical design reviews
• Perform functional prototype testing before
committing to tooling
• Generate precise production tooling
19. Issues in Layered-Based Manufacturing
• Staircase effect
• Layer thickness
• Accuracy
• Part orientation
• Support Structures
