DESCRIPTION
This talk was first presented at the Maryland Society for Educational Technology 2014 Common Ground conference. It is meant as an introductory talk about 3D printing and how to get started designing for 3D printing and printing even if you don't have a 3D printer. We discuss: * What exactly is 3D printing * What can it do * What it can't do * The uses of 3D printing in fashion, architecture, food, medical devices, and tools * Real world projects using 3D printing and everyday people * How 3D printing can be used in the classroom * Different types of 3D printers * Different types of 3D printing materials * Different software solutions for creating 3D designs * Some 3D printing resources

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
• Can be challenging to work with
• New ones coming out all the time:
• Thermoplastics
• Wood-like plastics
• Nylon
• Metal Infused
Software Options
• Tinkercad
• Free, web based, good for ages 6-99
• 123D Design
• Free
• OpenScad
• Free - programming based
• Minecraft
• Rhino, AutoCAD
