The gap between the tub and the nozzle surface can generate accumulated filament and lead to reduced flow. Unfortunately, it is somewhat common for the Ender 3 to have a faulty PTFE tube that does not sit flush with the nozzle surface, causing extrusion problems. If you are still having extrusion problems, you may be facing a deeper problem with your printer that adjusting settings and cleaning nozzles just cannot fix. We cover these processes in greater detail in our 3D printing troubleshooting guide. You can also use a thin piece of metal to gently coax the clogging filament through the nozzle. The most common method is to perform an atomic pull. There are a few ways to clean a 3D printer nozzle. If it begins to curl as it comes out, there is a partial clog in the nozzle. Run a short test print and carefully watch the filament as it is extruded. Though this is unlikely to be an issue for brand-new machines, if you have used your Ender 3 printer several times without problems and are suddenly facing extrusion problems, it is very likely that a clogged nozzle is to blame. If you are still having problems, follow our more comprehensive bed leveling guide to cover any nozzle or bed alignment issue that could be affecting your print quality. You can typically identify a poor Z-distance setting by a thin first layer.įollow the manufacturer’s instructions to reset and calibrate the bed leveling and nozzle settings. □ To reduce the risk of stringing and poorly set prints, be sure that you don’t change the temperature to more than 10 ℃ above recommended settings.Īdjusting the Z-distance, which is the vertical distance from the nozzle to the print bed, can typically improve layer uniformity and setting. Have a quick test print ready because you will likely have to print a few until you find the optimal settings for your printer. Increasing the temperature will increase the filament flow rate, which can improve very spotty or “broken” prints.Īs always, we only recommend changing one setting at a time, and any change should be in small increments (around 3 ℃ for temperature). Decrease speed and increase temperatureįlow rate is an essential aspect of print quality that is easy to overlook when tuning settings for a new filament or when setting up a new printer.ĭecreasing the print speed will ensure that the filament is laid evenly and has sufficient time to set before the next portion of the print is deposited on the build surface. If the filament looks thin and/or has portions missing, it is likely that your printer is not extruding the filament at an even rate. You can identify an under-extrusion problem by evaluating your test prints. Under-extrusion is by far the most common problem faced by Ender 3 users. We dug into the top five problems experienced when printing with the Ender 3 and covered the solutions here, so you don’t have to dig into old Reddit threads and forum posts that don’t provide the answers you need. After reading the manufacturer’s guides, going through a few “recommended settings” articles, and installing the recommended slicer, many makers have been extremely disappointed with poor print quality or problematic layer deposition. Owing to its low price and higher end features, a lot of beginner hobbyists buy the Ender 3 as their first 3D printer. The Creality Ender 3 is a fan-favorite 3D printer that retails far below the expected price for printers of this caliber. This guide covers the frequently reported complaints of Creality Ender 3 users and lists the most effective solutions for each problem.
