Not an answer to your question, but related: I think most (all?) plastics deform when a continuous force is applied. This is called creep.
In practice: if you bolt 2 parts together, your will see that after a while, the force between the parts will decrease due to creep. If this bolt was holding a lamp in a certain articulation, you might see it sags after a while. You have to retighten the bolt, and I think it will happen again and again.

The lamps I am making for these people are articulated. Though not played with on a constant basis I wonder if torsion forces would take a toll eventually. Same with the PC and the articulated model.
Also, as the part gets more brittle with age, would PLA pose an issue with age as kids are prone to dropping things. I am talking young kids, but not toddlers.
