Conclusion
Here's another one...
Quality of printed parts
Manufacturing Limitations
Intellectual property concerns
Selective Laser Sintering (SLS)
Process uses a CO2 laser to sinter or fuse a powder material. The laser traces the part cross section geometry layer by layer
4. Print it

Stereolithography
Fused Deposition
Modeling
Other methods
There is more than one way to 3D print!
Used in the first 3D printer. The UV laser beam draws out the 3D model one thin layer at a time, hardening that “slice” of the eventual 3D model as the light hits the resin. Slice after slice is created and an extremely high-resolution three dimensional model is formed.
The object is produced by extruding small beads of melted thermoplastic material to form layers as the material hardens immediately after it leaves the extrusion nozzle. It is one of the lesser expensive 3D printing methods.

3D printing
is a process of making a

three-dimensional

solid object
from a digital model
produced by
CAD
What is it?
How do 3D printers work?
You're probably thinking HOW that's possible.
The printer reads data from the file and lays down successive layers of liquid, powder, or sheet material, and builds up the model from a series of cross sections.


Strength, quality far from meeting military specifications

Most 3D printers can only print single type of material

Printing electronic circuits is a challenge




Aerospace Industry
Boeing 787 Dreamliner
Boeing incorporated 3D printed components on the new Dreamliner

30 components consisting mainly air cooling ducts

reduce time between design & manufacturing stages
Healthcare Industry
Dental Crowns
require custom fit for tooth

Uses of 3D printing
(*some of them)
Rapid Prototyping
Entertainment

Healthcare
Consumer Market
Aerospace
Education
...
Ignite a New Wave of IP Issues
One can easily copy, modify, share the digital design files through emails, bit torrents

Debates on who own the copyrights of the DIY printed
object

1. Have an idea or a need
2. Scan it!
3. Input scanned file & edit
Arts
3D printing allows artists to create objects that would be incredibly difficult, costly, or time intensive using traditional processes
Is 3DP science fiction?
Entertainment

Legal Responsibility
Who is ultimately liable for any damage or injury incurred by way of the 3D printing process and its resulting products ?
The designer ?
Supplier of 3D Printer ?
The Consumer ?
The Web host ?
Supplier may prohibit military from scanning and printing of replacement parts
Translates ideas into physical models

Validate form, fit & function
Consumer
At $900 a pair, it's not exactly fashion for the masses, but it's in the same price tier as other high-end shoes
Education
Encourages learning & iterative designing

Promotes innovation

Enhance students engagement

Develop Personal Learning & Thinking Skills (PLTS)
Future of 3D Printing in Singapore?
3D Printing is an emerging technology that has the potential to transform how the SAF operates today.

With this new technology becoming relevant for all kinds of people and industries, from small business owners to top defence engineers, it is becoming relevant for students as well. A 3-D printer and CAD system will give students an impressive working knowledge of an emerging technology and push innovation to the next level.

Additive Manufacturing is the name for this new developing technology.

Additive manufacturing is the complete opposite of Subtractive manufacturing

Subtractive manufacturing is the process of removal from a material to create something
Additive Vs Subtractive Manufacturing
History
The first working 3D printer was made in 1984 by Charles W. Hull of 3D System Corp

Hull invented stereolithography which is a printing process of the 3D printer

A number of patent on the concept of 3D printing was published by Hull

It wasn't known back then as it was very expensive and wasn't feasible for consumers
In the 21st century, the cost dropped drastically which allowed it to be on a more affordable market.

The cost of 3D printers was ranging from about $20,000 in 2010 to 2013

Now some are less than $2,000 today

Some printers are being developed under the cost of $1000 which makes the technology increase its availability to the average consumer
Cost of 3D Printers
CAD, an acronym for Computer Aided Design, is a software tool used by enthusiasts and businesses alike to produce 2-D or 3-D scale drawings and models.
Spare Parts for Weapon systems

Reduce uncertainty in predicting the amount of spare parts required

Print spares on demand for overseas mission support

Revolutionalise traditional inventory management

Do i even need stores?

Can i reduce manpower?

Significant cost savings
We are exploring the use of 3D printing to solve real problems
Size is a limitation for the home 3D printers

The home 3D printers are small so the products would be tiny

Required the skills to make a blueprint for a object
Seeing is believing
Allows experimentation of different design concepts within a short time frame at low cost

THE FUTURE IS EXCITING
WEIRD
Why is it important in education?
DSTA's Mission
To harness and exploit science & technology, and provide technological and engineering support, to meet the defence and security needs of Singapore.

DSTA performs the role of the defence science and technology arm of MINDEF and is also the procurement agency for the SAF.

We are responsible for implementing defence technology plans, acquiring defence materiel, and systems and developing the defence infrastructure.
DSTA was formed as a statutory board in March 2000
