What is 3D printing?

Additive process

Types of 3D printing

3 main types:

Extrusion Deposition

Granular materials bindingPolymerization 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 2 printer

How do I Print Something?

digital file of the 3D model

(.stl)

software program to ‘slice’ the model, configure the print and talk to the printer

But Where Do I Get The Models?

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

Considerations When Designing for 3DP

Objects must be closed

This is not really a concern with TinkerCAD, because all the shapes you’re working with

are already closed i.e. all the faces are surfaces.
