<p>Once the non stick coating wears off you'll notice degraded print quality over time and a more agressive sound from the print breaking free when switching layers as the print uses more and more force to break free from the tray with each layer when the non stick coating degrades. The good thing is this will not happen at once so you will start to notice telltale signs previously and you can lessen the wear at specific points of the non stick coating by using different parts of the build platform instead of printing exactly in the center each time.</p>
