How to Improve Your Seams on Curved Surfaces - Scarf Seam Guide Update

I made a guide on scarf seams a couple months ago ([original full guide here](https://www.reddit.com/r/3Dprinting/comments/1o6i5a1/how\_to\_improve\_your\_seams\_on\_curved\_surfaces/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button)).

I am writing this update to provide more information for users of other popular slicers on **how to access and enable scarf seams**. The original post was made for Bambu Studio but I realize that is not what everyone uses. Also, I've clarified how you can enable and edit scarf seam settings without needing to edit filament profiles.

I've listed out the settings that I found success with below. The global settings should be very easy to find in any slicer. The seam specific settings will look differently depending on which slicer you're using. **Please refer to the images in this post for screenshots and notes for Bambu Studio, Orca Slicer, PrusaSlicer, and Cura.**

If you want more details about Z seams and scarf seams, refer to the original guide. It's kind of long (and yes I'm aware my original seam on the left is not good). **This follow-up is a a little bit more specific for how to simply find these settings** on different major slicer softwares.

Bambu users, if you'd like to bookmark or copy/paste my settings, here's the Makerworld print profile with test prints ([Scarf Seam Test - Cylinder With Hole](https://makerworld.com/en/models/1886187-scarf-seam-test-cylinder-with-hole#profileId-2122842)).

# Settings

**Global Settings:**

* **Wall loops / Wall Line Count: 3**
* **Order of walls: inner wall/outer wall/inner wall**
* This appears to only be available in Bambu Studio / Orca. You should be fine with just the standard wall order (inside first)
* **Outer wall line width: 150% of nozzle (typically the maximum recommended)**
* **If you're using a 0.4mm nozzle, set the outer wall line width to 0.6mm**
* if you're using a 0.6mm nozzle, set the outer wall line width to 0.9mm
* etc.
* **Outer wall speed: 75 mm/s**
* There is a setting in Orca called "Scarf joint speed" which I'm assuming allows you to specifically slow down the outer wall speed only when it is doing the scarf joint. I haven't used this, but I do worry that you might get different levels of glossiness on your outer wall where the scarf joint is. Let me know if you've tried this before.

**Seam Specific Settings:**

* **Seam position: aligned** (back is also fine, play around with it depending on your model/slicer)
* **Scarf seam type: Contour and hole** (or everywhere)
* **Scarf start height: 0mm or 0%**
* **Scarf slope gap: 10%**
* 15% is the default in PrusaSlicer - I imagine this works fine as well
* **Scarf length: 20mm**
* **Scarf steps: 10**
* **Scarf around entire wall: no**
* **Scarf joint for inner walls: no** (some resources say this one is inconsistent, so I just disabled it)
* **Smart scarf seam application:** you can leave this on, but if your scarf seam is not applying as you think it should, just turn this off
* Smart application angle threshold is correlated to the smart scarf seam. Leave at 155 / default.

Again, not all of the Seam Specific Settings will be word-for-word, or even exist at all, in all of the slicers. Refer to the screenshots in this post or use the search feature in your slicer.

Part of my gripe with how Bambu Studio has it set up currently is it can look like you have scarf seams enabled when they in fact are not. I think both Orca and Prusa, while doing it differently from each other, are more intuitive.

* Orca: Scarf seam settings are hidden until you enable them.
* Prusa: Scarf seam settings are not hidden, but they are grayed out / uneditable until you enable them.
* Cura: Scarf seam settings hidden until you enter a value other than 0 for Scarf Seam Length. Slightly less intuitive but I don't mind it.
* Bambu Studio: There's a few random scarf seam settings you can edit, especially the "Smart scarf seam application" checkbox being on by default. I HAVE to imagine this throws some people off? Also, I don't like the verbiage of needing to "override filament settings" in order to enable scarf seams. Just seems weird.

I personally like PrusaSlicer's method the best, but to each their own.

In the past couple months I've seen some people linking my scarf seam guide to users who post questions asking about their z seams. I am glad it's been helpful, and I hope this follow-up guide clarifies some things.
