What is 3D printing?
1/7
Additive process
Types of 3D Printing
2/7
3 main types:
Extrusion Deposition
Granular materials binding
Polymerization by light
Extrusion Deposition:
FDM - Fused Deposition ModelingFFF - Fused Filament Fabrication
Solid Materials:themoplastics, rubbers, clay, silicone
Granular Materials Binding:
Selective Laser Sintering (SLS)Direct Metal Laser Sintering
(DMLS)
Powdered Materials:metals, thermoplastics, ceramics
Photopolymerization:
Digital Light Processing (DLP)Stereolithography (SLA)
Liquid Materials:photopolymer resins
Form 1 printer
How do I Print Something?
3/7
digital file of the 3D model (.stl)
software program to ‘slice’ the
model
software program to talk to the printer
But Where Do I Get The Models?
4/7
model your own
traditional CAD (computer aided design)
parametric design (writing code)
2D logo openSCAD toextrude vertically
MeshLab to position andmerge 2 .stl files
3D scanning
reconstruct from photos

“As an additive, rather than subtractive, process, it uses
less material and is therefore lighter and
cheaper.”
“Enables the design and production of previously
difficult of impossible structures.”
Is 3D Printing Over-Hyped?
Will It Become Mainstream?
7/7
Better Design Programs
Lower Cost
Ease of Use
Lower the minimum knowledge and effort required.
