Transcript of 3D Printing

Introduction to the different methods of rapid prototyping.
Current and future application of rapid prototyping
3D Printing

These are the topics for today's workshop.
3D Printing
CAD (Computer Aided Design)
CAD software allows us to:
Create detailed 3D Parts and Assemblies
Simulate and test designs
Rapid prototype (3D Printing!)
Present to Future use
Depend upon improving production speed and quality
What is 3D printing?
Creates solids from layers of material

We will spend some time learning how to use sketchup. Then we will briefly go over the capabilities of different computer aided design (CAD) programs.
Rapid Prototyping Methods
Everyone will have time to experiment with google SketchUp to make models that we will 3D print for you!
Great for solids and surfaces
Modifiable feature tree
Assemblies of components
Integrated simulation packages
Open Source
Useful for animation and rendering
Mesh-based polygons
Issues: compatibility with professional software
Open source
Renders a model via 3D scripts, more like programming.
Great for parametrization
Non-interactive (no GUI)

Selective laser sintering (SLS) uses a laser beam to melt and fuse powder layers
Great for prototyping, small complex parts, and DIYers
Industrial use
Aerospace Medical Tech
Consumer use
Low-Cost Customization
Local 3D printing centers
Refer back to the pros and cons
Explain how it will help
Describe the next steps
Based on Jim Harvey's speech structures
Making Models
Uses light cured resin and a controlled light source
Uses an inkjet to saturate powder with a binding solution
Electron beam melting (EBM) used to produce fully dense metal parts
Fused deposition modeling (FDM) is the most common type of printing.
Google SketchUp Tutorial
