Yeah, PLA, if you anneal it and use the right grade, has a strength to weight ratio the same as common Aluminum 3003 alloy, about 50MPa/(g/cc), which is also ab

  I do not have any experience using pla in an industrial setting. When talking about 1.75mm filament one can buy on a roll for a basic 3d printer, I can say I've printed a number of PLA things at 200-215C with appropriate slicer settings, speeds and such for beautiful looking output results, but all of them can be easily snapped in half by hand if I try.

    Many aluminum objects can be easily broken by hand too. The design of your object will greatly affect whether it can withstand a given force. I have prints that have seen hundreds of pounds of force in use with no problem -- printed on $200 printers with $18 filament. As a general rule, you will get best results if your part is printed so that the force this in line with the layers, not perpendicular to them.
