3. 3D printer?
Make a three-dimensional structure by additive manufacturing(AM)
AM – a process of joining materials to make objects from three dimensional (3D)
model data, usually layer upon layer, as opposed to subtractive manufacturing
methodologies. [European Commission 2013]

6. How?
Solid
- Heat the solid filament
type plastic on the head,
additive the layer through
the nozzle
- most popular used
- high accuracy and
repeatability
- high strength material
- no changing after
finishing the products
- application: vehicle,
robot, machinery industry
Liquid
- 1) Spray a photo-curable
acrylate composites and
gel type support material
together
2) harden the composite
using ultraviolet
- good surface
- realization the detail
shape
- can use various material
(rubber and transparent
material, …)
- application: consumer’s
goods, medical treatment,
electronics
Powder
- 1) for heating the
material , fire a laser to
powder type polymer and
metal
2) coagulate the
composite
- wider choice for
material (metal, …)
- high resolution
- fast modeling
- application:
construction, sculpture,
design
Considering material type…

7. How?
Extrusion
- FDM (Fused Deposition
Modeling)
Light polymerized
- SLA (Stereo Lithography
Apparatus)
- DLP (Digital Light Processing)
Considering additive type…
Sheet Lamination
- LOM (Laminated Object
Manufacturing)

WORLD MARKET
CAGR 18%
(billion dollar)
Considering the amount of sales, the personal 3D printer market
is biggest.
Also, the personal 3D printer market is best promising area.
(According to the Wohlers, the 6,500 high-end printer is sold.
The personal 3D printer is sold about 23,000. )

12. Real story Polaris (concept model/ function test)
Made prototype using injection modelling
- Modify tooling frequently
- cost: $60,000
Using FDM 3D printer
- make prototype (about $1,200)
- development optimized design
- 70% solidity
- Saving $58,800, 68 days http://www.stratasys.com/resources/case-studies/automotive/polaris
BMW (Jig & fixture)
Conventional fixture making
- Cost and time requirements were high
- Lack of design freedom reduced productivity
Using 3D printer
- have over 400 assembly fixtures
- Organic shapes maximize performance
- Sparse fill cut weight 72%
- Saving $244, 16.5 days 12

13. Current applications
Structure (concrete) Food
Plastic extruders DIY

14. Current state and Interest for 3D printer
Growth promoting factor Obstacle of growth
- Tech development:
3D printing performance improvement
-> increase the awareness and interest of
3D printing
- Cost down:
HW and SW cost down -> cost of finished
product down
- Develop various materials:
wider the application industry
- Appearance of easy SW (Google’s
sketchUP, Autodesk’s 123D, …)
- Usability: harder than 2D printer
- Required time: several hours or several days
- High cost material
(high-end material : 100~300 $/kg
low-end material: 15~35$/kg)
- Need to revision of law
(about copyright and design reproduction…)
