Limited material systems.
Possibly lower energy footprint (~60-90W)
What Materials Should We Try?
Each RP system is in need of materials.
We like 3D Powder Printers - FAST

Wood (Cellulose) /Nut-Flour (allergies)
Rocket Fuels/KNO3/Rocket Candy?
Plastics (all the colors of the rainbow)
Moss/Living Cells & Plants
Soaps (worst smell ever!)

Burke Museum, Seattle, WA
Polyethylene terephthalate (Dacron) -> PET
Polyethylene terephtalate Glycol -> PETG
What does that look like?
What does ~100 BILLION plastic bags/year look like? (Earth911.com)

If it is economically viable? (paper/cardboard)
Government mandated? (paper,etc)
If it is energy viable? (aluminum/steel cans)
How does 3DP help or hurt?
Using recycled or recyclable materials!
Lower energy footprint (personal 3DP 60-90 watts)
What to do with re-prints?

What happens if
the major buyer
stops buying
plastic recycle?
About 10% of ALL of the plastic we use as
humans is recycled world-wide!
WOOF- First Ever 3D Printed Boat
Made of 100% recycled materials HDPE
Big Red Printer 5x10x3 ft (1.5x3x1 m) (recycled plasma cutter)
Seafair Milk Carton Derby
(must be made of milk cartons/jugs)
1M printer < $1000 C. Whitefield Compositing Toilet By M.Rogge
Each of us must do our part!
Desktop Factory Competition, $40K prize for a low-cost filament extruder to reduce the cost of FFF materials by 5-10 X by making filament from pellets. Must cost < $250!
Hugh Lyman wins w The Lyman Filament Extruder II

3DP is a manufacturing process.
3DP contributes to MWS (may add non-traditional waste household waste).
3DP community needs to embrace environmental issues.
3DP can use materials friendly to environment.
3DP users will start asking for recycled materials (forcing the value proposition).
Recycled material systems will ensure a sustainable future for 3DP.
