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

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.
