Time/Cost Benefit Analysis
Prototyping is more accessible
A bit of History to understand the future
• FDM was developed by S.Scott Crump in 1980s and commercialized by Stratasys in 1990s.
• In 2006 some key patents expired and 3D printing revolution started
• Charles Williams in 1986 developed the SLA system and started 3D Systems to commercialize it
• Recently desktop SLA printers are becoming available• SLS developed by Dr. Carl Deckard in 1986. EOS is one of the
companies that is developing SLS printers. In January some of the key patents in SLS ecosystem have expired opening the door way to many more desktop SLS printers
FDM SLA SLS

1980 – 2006• Very limited use
• Only companies with huge R&D budgets used it
• Companies using 3D Printers only for moon shot projects
• Use was limited to plastics and metals molds
2006 to present• 3D Printing is growing
exponentially. • Schools and consumers are using
it• Companies using 3D Printers to
reduce inventory• Technology is getting adapted in
fields of bio printing and electronic printing
• Production grade rocket and airplane engines

Examples of Failed Prints
Thermoplastics
This is a plastic material, typically a polymer, that becomes pliable or moldable above a specific temperature or solidifies upon cooling
ABS PLA
Mechanical Property Flexible and strong Brittle and less flexible
Glass transition temp 90C – 110C 60C – 80C
Melting Point 220C – 250C 190C –210C
Sustainability Non – biodegradable Biodegradable
