What is 3D Printing?
• Additive manufacturing
• Material is placed, over time, one layer at a time
• A common first material is plastic
• “A hot glue gun controlled by a robot arm”
What is 3D Printing?
Three Steps
1. Design your 3D Model (you)
2. Slice the model into layers (computer)
3. Print (3d printer)
What can it do?
• Customized/personalized objects
• Prototypes
• Individualized printing/Print on demand
3D Printing is NOT…
• The new mass manufacturing
• It is not cost effective in terms of time or material costs
• The right tool for every job
3D Printing Benefits• Prototyping
• Gives your physical creations an “undo” button
• Personalized, Customized, “one off” manufacturing
• Print On Demand
• 3D Designs are cheaper to store than physical inventory

$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand, an open source hand which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money. !http://3dprint.com/2438/50-prosthetic-3d-printed-hand/

3D Printing in Society - Future
• Space
• Replacement Parts
• 3D Scanning
• Bio printing
3D Printing in the Classroom
• Cultural replicas
• Game Pieces
• Something that makes music
• Create characters for a stop-motion video.
• Design a model of your house, classroom, school, or local building.
• Phone case
• Make a missing piece for a building set (LEGO, K’Nex, etc.)
• Make items that show use of ratio, measurement, scaling, or geometry. You can also make small things bigger, like bacteria.
• Build an amusement park, zoo, aquarium, or wild animal park.

Tools of the Trade
• 3D Printer
• Software
• Additional Hardware
Types of 3D Printers
• Starting at $349 (kit)
• Ready to print $599
• More expensive does NOT equal better quality
• Other options:
• Dual Extruders (multiple colors/materials)
• Heated beds (new materials)
• Powder based
The Materials
• Polylactic acid (PLA)
• Derived from corn starch or sugar
• Cradle-to-cradle recycling
• Decomposes into water and carbon dioxide in 47 to 90 days (in the right compostable conditions)
The Materials
• Acrylonitrile butadiene styrene (ABS)
• Legos!
• Higher heat than PLA
• Really need a heated bed to work with
• Strong but not flexible (cracks, doesn’t bend)
The Materials
• Flexible Filaments
• Rubber like
