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
