4 3D Printing Problems and How To Fix Them

3D printing has revolutionized the manufacturing world, but like any technology, it’s not without its hiccups. Encountering issues in your 3D printing process can be frustrating, but many of these problems have straightforward solutions. Read on to learn more about four 3D printing problems and how to fix them.


One common issue with 3D printing is warping, where the corners of the print lift off the print bed, distorting the design. Warping can be a result of thermal stress or poor bed adhesion. Combat warping by using a heated print bed to minimize temperature discrepancies, or apply an adhesive to improve bed adhesion.

Clogged Extruder

A clogged extruder is another typical challenge that can interfere with print quality. A clog can result from using filament with an inconsistent diameter or from dust accumulation. Regularly cleaning the extruder and using high-quality filament can prevent this problem. If the extruder is already clogged, heating it and carefully removing the blockage can clear it.

Layer Lines

Layer lines or visible striations on the surfaces of 3D prints are another common problem, and are especially troublesome if you’re working with PETG filament. These lines are usually the result of low-resolution settings or an uncalibrated printer. To rectify this, you can adjust your printer’s layer height settings to a finer resolution or ensure your printer is properly calibrated.

Additionally, there are a few preferred methods for smoothing PETG filament and other filaments, like sanding and priming, that can also help minimize the appearance of these lines.

Incomplete Extrusion

Incomplete extrusion, often appearing as missing layers or gaps in the print, can be the consequence of a low extrusion multiplier setting or a jammed filament feed. Try increasing the extrusion multiplier setting in your slicing software, or check the filament feed for any jams or obstructions and remove them if needed.

Now that you know these four 3D printing problems and how to fix them, you’re well-equipped to ensure your 3D printing projects are completed with the highest quality possible. By identifying and understanding these issues, you can mitigate their effects and enjoy the fascinating world of 3D printing without unnecessary stress.
