Intro to and Designing for 3D Printing
Alex Ruaux | [email protected] | @molecularcode | #3dprinting
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
reconstruct from photos

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.
