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.
