Can you give evidence to it only lasting a year? I print in PETG which is the same plastic used by Coke to create their 2 liter bottles. Even "if" it only lasts a year, the cost of the plastic is cents so I'll just print another.

I'll pass down the schematics which are more durable than even plastic.

If you print another brick, what happens to the old brick? Another piece of trash for landfill?

PLA is easy to recycle, though as I said I mostly print PET. That does seem to be recyclable though I question the cost/benefit of doing so since the recycling itself has cost and it may weaken the plastic.

Personally I have a bucket filled with the scraps till I can figure out what I want to do. But I know I've thrown away far more plastic packaging than I waste printing so I don't stress about it.

Nevertheless your point is valid and needs to be considered as 3d printing becomes mainstream.
