New Technology

1. 3D printing

2. Content:
• Introduction
• Process
• Types
• Benefits
• Applications

3. Introduction
• An additive process
 Sequential layering
 Under computer control
• A rapid prototyping machine
• A developing technology

4. Difference between additive and
subtractive methods???

5. Process
Cad file is created
File exported to 3D pinting machine
Layer by layer we get the actual object

6. Types
Fused deposition
modelling
Stereolithography
Selective laser
sintering

7. Fused deposition modelling
Uses filament that is melted and extruded to the
base plate. The melted material is build up
layer by layer

8. Stereolithography
Use resin and photo polymer that react to light
source such as UV. When light exposes the
resin it hardens and bulids up layer by layer.

9. Selective laser sintering
Uses laser to fuse powdered material together,
again layer by layer. There is a lack of necessity
for any support structures.
