3. Create a CAD model of the design.
Convert the CAD model into STL format.
Slice the STL model into thin layers.
Construct the model one layer atop another.
Clean and finish the model.

4. Stereo Lithography
Laminated Object Manufacturing
Fused Deposition Modeling
Selective Laser Sintering
Solid Ground Curing
3-D Ink-jet Printing

steel; Non-ferrous metals such as Bronze;
Elastomers; Composites; Ceramics
Min layer thickness : 0.05mm
Surface finish : Rough
Build speed : Very Fast
Applications : Concept models, Limited
functional testing, Architectural & landscape

11. Prototyping
Rapid Tooling
Rapid Manufacturing
It is also used in other various industries like
aerospace,automative,jewelry,bio-medical
etc…

12. Almost any shape are geometric features can be produced
Reduction in time and cost from 50% to 90%
Errors can be detected at earlier stage
Material waste is reduced
No tooling is necessary
Poor surface finish
Limited strength
Accuracy is less

14. THANK YOU FOR YOUR ATTENTION
HAVE A NICE DAY
