The Problem with Nozzle Dragging on 3D Print: Solutions and Avoidance

3D printing is an exciting technology that allows people to create three-dimensional objects of any shape or complexity, using computer-designed models. However, while 3D printing is fun and easy to use, it is not always perfect. One of the most common issues experienced by 3D printing enthusiasts is nozzle dragging, also known as ooze, which can lead to a poor-quality print or even printer damage.

This blog will explore the problem of nozzle dragging and offer some solutions and tips to avoid it.

When Does Nozzle Dragging Happen?

Nozzle dragging happens when the printer nozzle scrapes or drags on the printed parts during printing, causing damage to layers, and aberrations in the print. The most common cause for nozzle dragging is that the nozzle is too close to the print bed. The nozzle should be at a sufficient distance to avoid touching the bed while still maintaining a close distance to ensure proper adhesion between melted plastic and print bed. To solve this problem, you must recalibrate the nozzle to the appropriate height. This means levelling the bed and recalibrating settings such as the distance between the nozzle and the bed. Make sure that the build plate is levelled and the distance is adjusted accurately every time before printing.

Another solution to nozzle dragging is to reduce the printing speed. When printing at high speeds, the extruder may be moving too quickly, causing melted plastic to drip, and the nozzle to catch onto the layers causing considerable damage. Try reducing the printing speed to avoid this issue. Slow and steady wins the print race!

Keeping the temperature of the printer in check is also essential when trying to avoid nozzle dragging. When the temperature is too high, melted filament is liable to leak, causing the above-stated damage. Conversely, when the temperature is not high enough, the filament will not melt, and the layers will not stick together properly. Experiment with the temperature until you find the right one that works for your printer and printing material.

Sometimes the printer’s nozzle size may not be ideal for the material you are using. Check your printer specs and use proper nozzle diameters for different types of filament. Smaller nozzles are more accurate and best for detailed printing but may require slower print speeds than larger nozzles. Similarly, large nozzles will allow faster and rough prints, more suited for crafting larger objects like masks or furniture pieces.


Nozzle dragging is a common headache for 3D printers, but it can be solved. By adjusting the nozzle height, reducing printing speeds, regulating temperature, and using appropriate nozzle sizes, you can avoid this problem and create smooth, high-quality 3D prints.

Take your time, and don’t give up when you face this issue. With these tricks, you’ll be crafting amazing 3D designs in no time.
