Rapid prototyping (RP)
Definition
Rapid prototyping is a layer based automated fabrication process for making scaled 3-dimentional (3D) physical objects directly from 3D computer-aided design (CAD) data without using part depending tools.
More concisely, it is a process of building a prototype in one step.
Construction of the part or assembly is usually done using 3D printing or “additive layer manufacturing” technology.
Historical development
The first method for rapid prototyping became available in the late 1980s and was used to produce models and prototype parts.
Historical development
In today’s industry, RP exceeding the scope of prototype model creation, expands the possibility of the layered manufacturing, into the next level, where parts for real-world engineering applications are fabricated.
Historical development
Titanium powder-based 3D printing technology is reported recently with many successful stories.
For example, a 3D-printed bike has been fabricated with the Titanium powder.

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.

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
