subject:Using Spiral Vase Mode for RC Aircraft Models (Wings, Fuselage) – CAD Parametrization and Slicer Limits
Hello,
I am testing the use of Spiral Vase mode in Bambu Studio to produce thin-walled parts for RC aircraft models (elevators, wings, and fuselage). When printing an elevator profile with a height of 308 mm, I achieved fantastic results:
Print time: 2 h 39 min (compared to 6 h 49 min with standard slicing).
Quality: A significantly smoother surface with no visible Z-seam.
CAD Workflow Used
To get Bambu Studio to recognize the model as suitable for vase mode, I used the following workflow:
I drew a profile with double the perimeter width.
I split the interior of the model longitudinally and introduced a 0.002 mm gap.
This gap runs through almost the entire inside of the profile (except for the leading edge/nose tip), creating a single continuous path for the slicer.
Reason for My Query and Future Plans
I plan to use this method for a complete aircraft build—specifically for complex geometries like tapered wings with variable chord and thickness as well as fuselage sections.
Since preparing and parametrizing these models in CAD will take several dozen hours of work, I need to gather as much information beforehand as possible and understand the slicer’s limits to avoid unnecessary errors and rework.
Questions Regarding Limits and Parametrization
By what exact criteria does Bambu Studio evaluate whether a model is suitable for Vase Mode?
What are the boundary CAD parameters (e.g., minimum/maximum internal gap width, maximum overhang angle, curvature radii) for the slicer to accept the model smoothly?
Are there specific geometric shapes in variable wing profiles or curved fuselages that cause the slicer to break the continuous spiral or fail?
I have attached sample files and screenshots for better illustration.
I would be extremely grateful for any advice, documentation, or recommendations on how to properly design these models in CAD.
None - it will always offer you vase mode, no matter how sensible or how absurd the model might be. That’s why you really need to keep a close eye on the slicing preview. It may not throw an error, but it will introduce many problems in the printed object.
Using vase mode for something other than its intended purpose is absolutely fair game - especially for this particular application - but you’re definitely pushing the slicer right up to its limits.
Some people here in the forum have had incredible success, while others have become frustrated by it. I’d try entering “wing” or “wings” in the forum search - you’ll find quite a few results.
Hi, I was checking the wiki to see how Bambu Lab handles “spiral mode,” but I’m still confused. I posted my thoughts in the comments section, but the comment isn’t showing up. There was a message saying it would appear after approval, but it seems like that isn’t happening: Spiral Vase mode | Bambu Lab Wiki
Has anyone ever received a response from support?
I dont think they want discussion on the wiki itself
Whats the question? Looks like you got it imported into BL and sliced. Aero filament is a challenge, be sure to start with the recommended profiles/settings
The wiki isn’t the right place for questions, thoughts or discussions. Comments there should only be added if they provide extra information or helpful advice.
For questions and troubleshooting, the forum is the right spot - and you’re already here.
Here, you also have the advantage of discovering the collective knowledge of many people. You already have a thread here that we’re in - you can keep it going, add more questions, or interact with other users.
For example, I gave you this advice:
So what did you figure out from this? What new information did you discover? What questions remained unanswered?
I don’t mean to offend anyone, but if someone simply replies that “some people succeed and others don’t,” that offers absolutely zero informational value. Telling me to “search for ‘wing’ in the posts” is equally useless. A helpful answer would be something like: “In spiral mode, if you set the wall thickness to 0.9 mm with a 0.4 mm extruder, it works fine. However, if you needed a wall thickness of 1.3 mm, it wouldn’t work—unless you configured that 1.3 mm section to consist of three passes, in which case spiral mode would work.” I realize this might seem like an odd question to someone who doesn’t use spiral mode, but anyone who does—and looks at my image—would likely have a few specific questions. Sorry for being so direct; I don’t know what cultural background you come from, but I’m from Central Europe.
Of course, I did search the forum, but I couldn’t find anything regarding spiral mode in this specific scenario.
Pal, my question was well‑intentioned. But you have to remember - we can’t magically know what kind of project you’re working on, what your experience level is, or what you’ve already tried. Without that context, it’s hard to give you the detailed help you’re looking for, especially with something as specific as this.
You naturally have far more information about your own project than anyone else here, yet your message reads as if we should already understand all the details. It’s not that people don’t want to help; it’s simply that we need more information from you to tackle such a complex problem - like sharing the 3MF file, for example.
Give us a bit more to work with, and you’ll get much better support.
We can’t possibly know that. Instead of getting irritated, a simple “I couldn’t find that information” would be enough. Just keep in mind that everyone here is helping in their free time, without getting paid. They don’t have to assist you - but they choose to.
Of course, you don’t have to take the offer - it’s totally fine to decline, no hard feelings - but I’m going out of this thread in a respectful way. If you’ve found a solution, feel free to post it - others will surely appreciate it.
