What is 3D printing?
• 3D printers can create physical
forms from a 3D digital model
• 3D printing is an ‘additive’ method
of manufacture
• What is meant by the term ‘additive’?

Disruptive technologies
• 3D printing is often described as a
‘Disruptive Technology’
• A disruptive technology is one that displaces
an established existing technology
• It might be a ground-breaking product
that creates a completely new industry
or just a new way of doing something
• In groups discuss why the iPhone,
launched in 2007, was seen as a
disruptive technology
• How has the smartphone changed
the way we live our lives?

A brief history of 3D printing
• 1980 saw Dr Kodoma attempt the first layer by layer 3D printing
• 1983 sees Charles Hull use UV light to harden resins and register
the first successful stereolithography patent
• 1989 witnessed Scott Crump patent Fused Deposition Modelling
• 1999 brings medical advances with 3D printed organs
• 2008 unveils the first 3D printed car
• 2009 allows the FDM patent to be available to the public,
triggering a surge in companies producing 3D printers
• 2013 and the first transplantable 3D printed kidney is created
• 2014 and NASA create the first 3D printed parts in space

Which materials print?
• Many materials can be 3D printed
• Concrete
• Metals (powdered)
• Chocolate and other foods
• Even living tissue
• The most common materials
used are polymers
• What is a polymer?

Types of printable polymers
• The polymers can be in different forms
• Most common is a roll or reel of filament
• Other forms are liquid resin and powder
• Some polymers are made from fossil fuels,
in particular oil
• Biopolymers, such as PLA (Polylactic acid),
are plant based and are biodegradable
• What is the environmental impact of
using oil based polymers?

The varied uses of 3D printing
• As 3D printing has developed so have its uses
• 3D printing is already widely used in products and
places that you might not even realise
• The 3D printing market is expected to grow to
£15.5 billion by 2020
• You can even buy a
3D printing pen!
• How could a 3D pen aid
designing in schools?
