In 3D printing, "seam" refers to the visible line or surface gap formed during the printing process. These gaps occur when the printer stops and restarts its motion at the end of each layer or each movement path, resulting in the stopping and starting of the material flow. This process leaves visible traces on the surface of the printed object, appearing as a line or gap.
There are some ways to deal with.
We can get known about form here.

A right seam postion choice can reduce influce from seam.
There are four choosing mode for us.

We can use some tool like Scissors and file to remove the seam manully.
Applying paint at the seam is also a great option to hide the seam.
To reduce the seam in 3D printing, you can try adjusting the following print parameters:
1.Print Speed: Slowing down the print speed can reduce the abrupt stops and starts of the print head between layers. A slower print speed can result in a smoother surface and reduce the visibility of the seam.
2.Temperature: Adjusting the print temperature can affect the melting and solidification process of the printed object. Experiment with different temperature settings to find the optimal temperature range for your printing material. Different temperatures can affect the seam's appearance due to variations in meltability and object adhesion.
3.Layer Height: Choosing a smaller layer height can improve the resolution of the printed object, thereby reducing the visibility of the seam. A smaller layer height can make the seam smoother and harder to detect. However, keep in mind that a smaller layer height may increase the printing time.
4.Infill Density: Increasing the infill density can enhance the structural strength of the printed object but may also result in more visible seams. Try reducing the infill density to decrease the number and visibility of the seams. Choose the appropriate infill density based on your printing requirements and the object's purpose.
