2. INTRODUCTION
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The
creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying
down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced
horizontal cross-section of the eventual object

3. History
26.08.2015
Yep, 3D printing is older than you might think. In fact, 3D printing has its roots in the 1980s. In 1984, Chuck Hull,
invented a process called “stereolithography” which used UV lasers to solidify photopolymer that created 3D parts
layer by layer. In 1985, Materialise CEO Fried Vancraen was a young man making his own non-computer “FDM”
models. Five years later, he founded Materialise, one of the first 3D printing companies.

4. How does 3D printing work?
26.08.2015
It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD
(Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of
a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object

3D printing was primarily used for prototyping, but is
now being used for production-ready pieces.
Ford is currently using 3D printing to make large selections of its car parts for testing. According to Ford, the company can save up
to $493,000 a month of work with this production method.

NASA researches are currently working on figuring out how to bring 3D printing technology to space. The idea is to send robots
ahead of astronauts to construct buildings and infrastructure on lunar surfaces

7. Something to Talk About
In Belgium, biomedical specialists implanted a 3D-printed titanium jawbone into an 83-year-old woman.

8. License to Print
The James Bond movie, Skyfall, used 3D print technology to produce models of 007's famed Aston
Martin DB5 luxury grand tourer.

9. 3D Print Your Own Weapons
This is one that is highly interesting both to civilians, the army and the MOD alike. Already people have printed their own
3D printed guns. Both home users and the government are investing time and money into this part of 3D printing
technology.

10. 3D printing is in the movies you watch.
3D printing fun fact: 3D printers are already being used for movies. Props can take hours of hard work to create and apply.
With 3D printing, many of those props can be created and re-created faster, easier, and without starting from scratch.

12. Examples & applications of 3D printing
26.08.2015
Applications include rapid prototyping, architectural scale models & maquettes, healthcare (3d printed prosthetics and printing
with human tissue) and entertainment (e.g. film props).
Other examples of 3D printing would include reconstructing fossils in paleontology, replicating ancient artifacts in archaeology,
reconstructing bones and body parts in forensic pathology and reconstructing heavily damaged evidence acquired from crime
scene investigations.
