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.
