What is 3D printing?

What is 3D printing?Making three dimensional solid objects from a digital file.

Created by laying down successive layers of material until the entire object is created.

How does 3D printing work?

How does 3D printing work?Starts with making a virtual design of the object you want to create.

Use CAD file using a 3D Modeling program

Use of a 3D scanner

3D scanner makes a 3D digital copy of an object.

How does 3D printing work?Microsoft and Google enabled their hardware to perform 3d scanning, a great example isMicrosofts Kinect (Using Kinect Fusion)

A clear sign thatfuture hand-held devices like smartphones will have integrated 3d scanners.

How does 3D printing work?3D modeling software slices the final model into hundreds or thousands of horizontal layers.

Whenthesliced file is uploaded in a 3D printer, the object can be created layer by layer.

The 3D printer reads every slice and creates the object, blending each layer with hardly any visible sign of the layers, with as a result thethree dimensional object.

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS)The ability of SLS to produce several pieces at one time.

Good choice for Direct Digital Manufacturing (DDM) of products requiring strength and heat resistance.



Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM)Plastic filament or Metal wire

3D Printing Industry

3D Printing IndustryMedical industry

Improved quality of care through 3D printed implants and prosthetics never before seen.

Tissue engineering applications where organs and body parts are built using inkjet techniques.

Layers of living cells are deposited onto a gel medium and slowly built up to form three dimensional structures

Medical Industry

3D Printing IndustryAerospace & Aviation industries

For a large part, be derived from the developments in the metal additive manufacturing sector.

NASA for instance prints combustion chamber liners using Selective Laser Melting.

Aerospace & Aviation industries

3D Printing IndustryAutomotive Industry

Simple concept models for fit and finish checks and design verification

Functional parts that are used in test vehicles, engines, and platforms.

Automotive Industry

Industrial Printing

Industrial PrintingRapid Prototyping

Manufacturers use 3D printers in their design process to create prototypes for traditional manufacturing and research purposes.

For example, Nike uses 3D printers to create multi-colored prototypes of shoes. They used to spend thousands of dollars on a prototype and wait weeks for it.

Now, the cost is only in the hundreds of dollars, and changes can be made instantly on the computer and the prototype reprinted on the same day.

Industrial PrintingRapid Manufacturing

Manufacturers use 3D printers for short run custom manufacturing.

In this way of manufacturing the printed objects are not prototypes but the actual end user product.

Personal Printing

Personal PrintingMainly for hobbyists and enthusiasts.

Rapid development within this new market printers are getting cheaper and cheaper.

Prices typically in the range of $250 $2,500.

Future

Future3D Printing technological development will change the nature of commerce.

End users will be able to do much of their own manufacturing rather than buy products from other people and corporations.

3D printers capable of outputting in color and multiple materials already exist.

Will effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences.

3D printing will change the manufacturing world.
