<p>I picked up a roll of Overture matte black PLA, and the surface of both the filament and the printed object <em>feel like</em> paper. This made me wonder if it contains wood-based fibers like &quot;wood PLA&quot; does, and if so, whether it's abrasive and harmful to the nozzle. In the past I wouldn't have cared, but I'm using a CHT now and would like to avoid ruining it since it's expensive and I don't have spares sitting around.</p>
