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
Fashion/Retail• Faster production of unique clothes
and shoes
Applications
Aeronautics• Real-time creation of food and tools
in space
