<p>I came across a new Steel infused PLA from <a href="https://colorfabb.com/steelfill" rel="nofollow noreferrer">Colorfabb</a>. On the store page someone had asked, what happens if it was exposed to water, would it rust. I am actually, not sure what would happen. I am interested what the effects of leaving in the elements a 3D printed object made of the 2 most common type of fused materials. </p>

<ol>
<li>Wood Infill</li>
<li>Metal Infill (not stainless steel)</li>
</ol>

<p>Would it be preserved by the PLA coating it, or would, over time, rust and dissolve? Would the wood last forever, or will the print get discolored and become mulch? </p>
