If it is energy viable? (aluminum/steel cans)
How does 3DP help or hurt?
Using recycled or recyclable materials!

49. 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.
