3. Rapid Prototyping
• Prototyping is systematic approach for developing, testing and
manufacturing a prototype to meet the required quality.
Dr.K.Ravi Kumar, Professor- Mechanical Engineering 3

4. Why rapid prototyping
• Faster product development
• Part complexity
• Reduction/ combining of parts
• Cost saving
• Reduction in Labor
• Reduction of wastage
• Improvement in Marketing
• Consumer Satisfaction
• Systematic approach
• Feedback

5. Additive Manufacturing Vs 3D printing
• Additive Manufacturing (AM): Additive manufacturing is the
industrial standard name for 3D printing that builds a three
dimensional part by depositing/adding materials layer by
layer as per the 3D CAD model.
• 3D printing: 3D printing is the most common name used by
the media and the general public to represent additive
manufacturing. The 3D component is fabricated by adding
materials layer by layer from the CAD model data.
