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.

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.

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.

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.

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.

WHY 3D PRINTING?

Increase Innovation Improve Communication Speed Time to Market Win Business

APLLICATION

Healthcare

Design Prototypes

Education

Reduce material wastage

More local manufacturing

Increased customisation

› Limitations of size› Cost of printers› Limitations of raw material

Advantages & Disadvantages:

› Rapid production of prototypes› Increased employment opportunities› Low cost of production

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.
