3D PRINTING

Definition

• Creating 3D solid objects using additive process

• Additive: successive laying down of layers of material

Brief History

• 1983 – Charles Hull invents stereolithography

• Stereolithography: From digital data to tangible solid object

• 1988 – Technology made public• 1996 – 3D printer was used

How It Works

1• Create design using CAD or

modeling software

2• Send design to 3D printer in .STL

format

3• Choose material (e.g. plastic,

paper, rubber, metal)

How It Works

4• Filament material is fed to print

head

5• Printer heats or melts filament

material

6• Material is sprayed or squeezed

layer by layer

How It Works

4• Object is bound by laser

5• Printer heats or melts filament

material

6• Material is sprayed or squeezed

layer by layer

Advantages

• Revolutionize manufacturing by enabling individuals to create products

• Various materials are used• Plastics can be recycled• Applications in all industries

Applications

Health/Medicine• Produce hearing aids, leg braces

and even skin grafts

Applications

Prototyping• Faster and more accurate creation

of models

Applications

Manufacturing• Tools, musical instruments, furniture

and even bikes can be homemade

Applications
