Prints well so far. Haven't used it with abrasives yet but am waiting for the nylon carbon fiber to arrive on Monday. But PLA is great for my purposes. Much better than the brass nozzles I've bought so many. I'm no printing expert and just recently my printer was up and running again after many months of head scratching and swearing. In the first few months of using this printer, I went through many brass nozzles that wore out after repeated contact with my work surface or other reasons. Noob mistake, but probably better off getting this from a jump.
