2. • Customer demands fast delivery
• Traditional production time needs to be eliminated
• Time lost on concept design, manufacturing,
assembly and testing

3. •How to recover this time?
•How to over come this slower trend?
•Can anyone wait in this technology-age?

4. • RP is the technique of physically modelling the
design using special technology.
• produce models and prototypes from model data
(3D-CAD), MRI scan data and data created from
3D-Digitizing systems
• Additive approach for building shapes. RP
Machines fabricate plastic, ceramic and metal
powders using thin, horizontal cross-sections of
computer model.
• Few companies using to RP produce final parts
also.

5. • Creation Of CAD model
• Conversion into STL format
• Slicing of STL file into thin Sections
• Building Part by Layer by Layer
• Post Processing, Finishing & assembly
