If you’re shopping for a top-tier printer, you should learn how to fix 3D printer issues. Premium 3D printer owners should understand the basic issues that hold back model integrity and print quality. While mechanical failures and critical errors are difficult to diagnose, you can fix common issues with simple steps. So, if you’re looking for the correct solution to a frustrating problem, learn how to fix a 3D printer.
With any 3D printer troubleshooting guide, learning how to clean a 3D printer is a great place to start. You can ensure a great 3D printing experience by keeping the print bed and nozzle clean. Additionally, understanding how to connect a 3D printer to a computer can give you granular control over 3D print file preparation and slicer settings.
Regular 3D printer maintenance will keep moving parts like the drive gear and the 3D extruder.
Most beginning 3D printer users will have to learn basic maintenance, like how to fix a stringing 3D printer. That said, some problems, like mastering how to fix a warped 3D printer bed, are much more challenging. While 3D printer repair can get pretty complicated, there are some simple problems that you can fix without expert intervention.
Clogged extruders and nozzles are the most common cause of a failed print. You can fix some clogs with a needle, but only if there’s the filament is impure or expired.
Additionally, electrical issues and defective drives can cause the extruder to malfunction. The extruder temperature can get too high, causing wrapped prints. Consult an expert if you’re uncomfortable working with electrical hardware.
Warped 3D models are a common issue with older 3D printers since most modern units have a heated print bed. Unless you have an old model, your warping 3D prints are due to inadequate bed adhesion. As the model cools, the loose segments separate from the print bed and warp upward.
Apply glue stick to the print bed and ensure it is level before attempting another 3D model. Additionally, make sure the heated print bed is active and operating correctly.
3D models may crack between layers, and you’ll see imperfections like gaps along the outside walls. Your print temperature is too low, causing a lack of adhesion between layers. Ensure your 3D printer can supply the proper temperature for the filament you’re using.
Do not set your printing speed too high because the print temperature can get too high, causing deformed models.
If your 3D models are sagging or warping along the top layers, your printing temperature is too high. You should either lower the printing temperature or switch to a filament that can handle a hot nozzle.
Stringing happens when a small amount of filament drips between pieces, causing a thin string. If the printer’s temperature is incorrect or the retraction is off, you’ll experience stringing. Check your slicer program’s advanced settings to limit stringing.
STAT: A 2019 Global EY study showed that 81% of South Korean companies applied 3D printing tech in their businesses, making them the top nation for industrial 3D printing. (source)
