Model Warping, Falling Off, or Collapsing
![](https://hub.bblcdn.com/860874445306294272.png)
Warping, falling off, or collapsing during printing is usually caused by shrinkage and insufficient adhesion to the build plate.2024/07/16 20:08
Different Areas of the Model Have Different Gloss
![](https://hub.bblcdn.com/860875364866654208.png)
The filament's surface can change from shiny to matte during printing due to factors like temperature, speed, layer height, minimal layer time, and cooling.2024/07/16 20:08

Model Interlayer Cracking
![](https://hub.bblcdn.com/860879152394469376.png)
Interlayer cracking happens when the bonding between printed layers is weak, resulting in the layers disconnecting. 2024/07/16 20:08
The Filament Sticks to the Nozzle
![](https://hub.bblcdn.com/860879359416926208.png)
A small amount of filament sticks to the nozzle, causing material shortages, roughness, and other issues in the printed model.2024/07/16 20:08
Bad Overhang
![](https://hub.bblcdn.com/860880095218331648.png)
When printing overhangs, the extruded filament may not cool in time and bond properly, causing it to droop.2024/07/16 20:08
Bad Bridging
![](https://hub.bblcdn.com/860880617258184704.png)
Poor bridging quality occurs when the extruded filament does not bridge smoothly.2024/07/16 20:08
Stringing and Oozing

Excessive nozzle extrusion or abnormal molten filament flow.2024/07/16 20:08
Seam
![](https://hub.bblcdn.com/861099734355505152.png)
In FDM 3D printing, a seam is formed at the junction of the starting and end points of each layer of printing, which is a normal phenomenon.2024/07/16 20:08
