In general, yes, 3D printed items can endure a lot of wear and tear at the hands of exposure to the elements. Keep in mind that 3D printed parts can end up in automobiles and even aircrafts, where it must withstand a lot of exposure and usage.PLA is not extremely to UV, meaning after long periods of exposure to sunlight, it can eventually lose its colour. The main downside to PLA is If exposed to hot or humid environments for several years, the PLA can begin to degrade and lose its shape, as it is biodegradable. ABS on the other hand, can endure elemental exposure better. However, ABS is weaker than PLA when it comes to physical pressure applied to the material, and PLA has the ability to endure a larger range of temperatures.Metals and Charged Plastics are also quite durable. Metals can suffer from oxidation after years of usage if not treated against rust, however, this only applies to certain metals such as silver. Charged plastics in particular can withstand a lot of usage before weathering, as they are reinforced by metals or other materials.
