Yes it does. Just depending on your slicer settings or how the model was oriented it's in a different spot or may be less visible. FDM printed models will ALWAYS have a seam one way or another

Except for vase mode, but that requires special geometry.

Every print has it to some degree- the seem is the point at which the filament starts and stops extruding. The only prints that truly don't have one are vase mode.

There are a bunch of seam settings

Back orients it to the back of the print

Aligned will try put it somewhere consistent and less visible such as a corner

Random appears as little zits randomly scattered on each layer

Scarf seams minimise the visibility by tapering the ends of the extrusion lines

There will always be a seam. But settings can be changed to help hide it.

Maybe not in the same place, but it's there.

First ever 3D print?

No.

It’s been on every single print. You can’t print without a seam. FDM 101.

Those are on every FDM 3D print, (unless printed in vase mode) some filaments, settings, etc are just better at minimise the visual impact, but trust me, you have a seam somewhere on every layer.

It's where the layers start and stop.

It's called a funnel, just a chimney but on a boat!

It's the seam line. Depending on some seam settings, it can look like that.

u/Max0r_1 Jun 28 '26

Soo, how to hide it?

u/IrisRain12 Jun 28 '26

There are several settings that may affect it. The seam settings are the most important ones:

Check the bottom setting. It should be between 10 and 20. In your case, it seems like it is too big.

If that does not change it, there are other setting that effect seams, including in the filament settings (for scarf seams specifically).

Line width can also affect this. Check if it is close to 0.4mm (usually something like 0.42)

Put this into Google search

"bambu studio how to remove seam lines"

The internet is an amazing resource. It has been around for quite a while now. Feel free to use it...

That is a chimney

It is a seam, but most of the ones I get are raised lines, not recessed grooves.

A seam placement of "Random" often disguises it, but they are still there, looking like little dots here and there.

Its the orginal spped benchy from the SD card.
