3D printing is an additive manufacturing process that builds 3D objects layer by layer using digital files. It allows for rapid prototyping and production of customized parts. The document discusses various 3D printing technologies like stereolithography and multi-jet modeling that use lasers or inkjet printing to bind powder or liquid materials. Applications include healthcare, design prototyping, education, and more local manufacturing. Advantages are rapid production and customization while disadvantages include limitations of size and cost.

3. WHAT IS 3D PRINTING?
 The technology used for printing physical 3d objects
from digital technology is called 3d printing.
 It is also called RAPID PROTOTYPES.

4. GENERAL PRINCIPLES
Printing:
To perform a print, the machine reads
the design and lays down successive layers of liquid,
powder, or sheet material to build the model from a series
of cross sections.

5. STEREO LITHOGRAPHY
 Stereo lithography is a process for creating three-dimensional objects
using a computer-controlled laser to build the required structure, layer
by layer.

6. MULTI-JET MODELING (MJM)
 This again builds up objects from
successive layers of powder, with an
inkjet-like print head used to spray
on a binder solution that glues only
the required granules together.

7.  It creates the model one layer at a time by spreading a layer of powder (plaster, or resins) and
inkjet printing binder in the cross-section of the part.
 Allows for the printing of full color prototypes.
 inkjet 3D printing is optimized for speed, low cost, and ease-of-use.

8. WHY 3D PRINTING?
 Increase Innovation
 Improve Communication
 Speed Time to Market
 Win Business

9. APLLICATION
 Healthcare
 Design Prototypes
 Education
 Reduce material wastage
 More local manufacturing
 Increased customisation

10. › Limitations of size
› Cost of printers
› Limitations of raw material
Advantages & Disadvantages:
› Rapid production of prototypes
› Increased employment opportunities
› Low cost of production

11. CONCLUSION:
 Nothing communicates ideas faster than a three-dimensional part or
model. With a 3D printer you can bring CAD files and design ideas to
life – right from your desktop. Test form, fit and function – and as many
design variations as you like – with functional parts.
