Error: 776 non-manifold edges

Don’t know how many Mac users are also in the X-1 Carbon who have tun across this error warning:

“The “Fix Model” feature is currently only on Windows.
Please repair the model in Bambu Studio (Windows) or CAD software”

Not available on a Mac.

Anyone heard any rumors regarding this issue?

I happen to have a pc with Windows and installed Bambu Studio and uded this feature. It sliced perfectly with zero errors. Will print and wait and see the results.

MACs don’t have this feature simply because in the world Apple, nothing ever goes wrong so the notion of a repairing something like an STL mesh with a hole in it just simply does not happen. One can find this right next to the rainbows and Unicorns in their walled garden of perfection. :rofl:

BTW: There are a number of online resources that will fix a non-manifold mesh. Here’s just one example.

Your right about the things which shouldn’t happen, but I’ve been a Machesd since ‘86 and certainly Apple can ha an error within their system and even the dumbest of all like when the Apple logo (lighted) was upside down on the PowerBook (1999-2001). I’ve gone through at least 16 Macs through my tenure of being a Machead with relatively few major issues. But, when a programmer take on the issue with a message regarding…error #776 and mentioning a fact (indirectly) that you can fix this issue with a pc (with Windows) to me seems somewhat unclear.

I’m a newbie in the 3d printing arena and have made simple and dumb mistakes like many others like using petg on a pla print plate…oops. Have done some other. But throughout my almost 40 years do understand that one program “cannot” do 100% of a project unless you’re typing up a letter or a spreadsheet.

When working with cad programs with a goal of a quality 3d print or design…I’ve found and discovered a numerous amount of resources on the internet i.e. . shape3d…tinkercad, etc.

A quick example is designing a simple sign with some stl files included within the content of the sign. When merging or including these stl files to create a single object, I kept getting the #776 error. So I loaded Bambu Studio on the pc and walah…fixed…saved…exported…imported to Bambu Studio on my Mac…perfect print.,.almost because this was also my first multi colored print attempt.

Sorry about this lengthy text… but can you give me some direction regarding your reply. To me, this appears to be above my paygrade.

Thank you

My time in the computer industry dates back to the Apple II and the first CPM 8086 PCs so I know what your feeling. My post was intended to point out in a light hearted manner, the bullying nature of Apple and this coming from someone who worked alongside those arrogant assholes in Cupertino when I wasn’t visiting the other arrogant assholes across town in Santa Clara.

The point is, Apple ain’t giving you ■■■■ they deem you don’t need. And that has been my contention since the Lisa first came out. I’m forced to use use Macs in my line of work but at home I choose to use open architecture whether that be Wintel or Linux because to me, my money my choice. As a system builder, I even once built a Hackintosh just to give the middle finger to Steve Jobs.

Back on topic. Since the fix-manifold feature is baked into Windows and Linux has enough open source add-ons, it’s really not within the power of Bambu to rearchitect the host OS. Even if they wanted to, Apple will find a way to stop them because you know what? The internal unspoken Apple policy is that nobody messes with our sandbox and if you spot them in our sandbox, piss in their sand bucket. That’s just the Steve Jobs way and even 12 years after his death, that legacy lives on. He was the biggest prick in Silicon valley if not the planet but had mindless sycophants overlooking his egregious treatment of his customers and for crying out loud, he even screwed his own partner Woz who couldn’t have been a more kinder opposite to him.

So what I was trying to do with the link I gave above was to give poor Apple users an option to overcome Apple’s shortcoming in providing an OS level utility. That link is intended to be a work around to the broken mesh problem. Maybe Apple will some day add this feature maybe not. But you can count on this, that will likely never happen until it’s good for Apple not their user base.

I just assumed that they implemented that feature on Windows but not Mac, I didn’t realize it was an Apple limitation.

I use a MacBook for work. I have a virtual PC on it and my desktop computers are PC. I haven’t had to use the feature yet.

Great reply!! I to started with the Apple II then moved on. Believe it or not’m a simple hobbiest. It’s always been my fascinatio with these gadgets. The simplest work around for me is to transfer my file to the pc and let it do its magic, then put back to my Mac and move on. For some reason when I’ve tried to print dro my laptop (pc) there appears to be a brain cramp with no results. Probably pilot error.

I do agree with your anti Apple, but I’ve never been to or wish to go to California. It it probably the most beautiful states…but some have ruined it on more than one way.

Thanks for your reply.

Bottom line is…I’m obviously not a programmer and thought that Bambu Labs either did (wrote) Bambu Studio or a programmer from Microsoft or Apple. One of life’s mysteries :thinking:.

At the risk of going slightly off topic. This is not so much as a Apple limitation in as much as it is a Windows 10 feature.

On The Subject of Defective Manifolds - Win 10 Toolbox

When Microsoft first started on the trail of augmented reality - there was a whole suite of baked-in 3D utilities installed in Windows 10 back in 2015. 3D Viewer, 3D painter and various augmented reality extensions. The 3D viewer if you haven’t already enabled it, as an example is a very cool utility that allows one to view STL thumbnails right in Windows explorer. It should be noted that Microsoft was pursuing the $22Billion Augmented Reality contract with the DoD and 3D was a big part of it.

Also with this suite of utilities came the first appearance of the 3D Objects folder. For me, it was a waste of real estate and an annoyance for many until I took up 3D printing and realized how much free stuff Microsoft had baked into Windows 10 that supports 3D.

In case folks didn’t know. Everyone on Windows 10 has Paint 3D which is the 3D version of MS Paint. Did you know you can created Printable objects with it and save it to a 3MF file for printing? They even have a rich library of detailed objects.

Then there is 3D Builder which is more CAD-Like utility that Microsoft envisioned would create this ecosystem of 3D Printer Owners and industry that would allow one to create models right from the desktop. They envisioned that a whole new generation of VR gaming authors might emerge if they gave them tools to create 3D objects and characters.

But did you know, as with Paint 3D, you can also manipulate an STL file and then save it as any number of 3D printer file formats? If you have a USB 3D printer and the correct driver(I believe Ender and Prusa models are supported) then you can print right from the app itself.

So why am blathering on about this? The whole point of the “fix model” feature that is baked into Windows and that Bambu Studios uses, was in support of all this augmented reality and 3D modeling features in Windows 10. You see, Microsoft quickly ran into the same problem every other Mesh based program has such as Blender and that was a broken mesh or defective Manifold.

As an example, the simplify feature in Bambu Studio has an equivalent function in 3D builder. Likewise, if one has a defective manifold, the viewer will note that it is broken and allow you to fix it.

While this may all sound cool, and it is, the whole augmented reality hype quickly came to be a bust and all these utilities are starting to be deprecated and no longer install as default. You can still get them for free at the Microsoft store.

When it comes to 3D printing, Microsoft was trail blazing back in 2015 and it went nowhere because like so many things coming out of their Labs, Google too, once invented, there was nobody who was assigned to making it something that could be monetized and therefore it was never promoted. I’ll wager that the vast majority of 3D Printer enthusiasts don’t even know these tools are available or if they did, they may have discovered what I discovered in that these are great free technology demonstrators in search of a problem to solve. :rofl:

For anyone who is not sure if they have these on their Windows desktop. Just hit start and type “Microsoft Store” and when it launches, type “3D” and if it’s not installed, click on it.

Or simply click here and the web page will guide you to the same function.

Wow…great info…at the airpitt

Something just happened to my reply. Goin out of town for 8 gays… no computer👍

I’m at the airport…so I’ll get into your fantastic reply when I get to NC.

Thank you👍

Could manifold repair in Windows be going away, or is this article about something else?

"Microsoft has added Windows Mixed Reality to its online list of deprecated Windows features, meaning it is no longer under active development and isn’t well supported. The page explains, “Windows Mixed Reality is deprecated and will be removed in a future release of Windows. This deprecation includes the Mixed Reality Portal app, and Windows Mixed Reality for SteamVR and Steam VR Beta.”

When the industry uses the term deprecated, it’s a fancy way of saying that no more development effort will go into supporting it and it may eventually go away. The euphemism for a product being eliminated is “Sunsetting”. If you consider that Microsoft has still loads of legacy software like Solitare that is still in Windows from 1988, unless a piece of software either interferes with future compatibility or future business objectives, Microsoft usually doesn’t sunset a utility.

That being said, there are tons of indications an articles that these features and in fact the 3D Objects folder itself, is no longer part of Windows 11.

Given Microsoft’s history, I would think a five year horizon is a safe bet. But in the end, it’s really anyone’s guess. And let’s be real, by then 3D printing will be obsolete and we’ll all have Star Trek-style replicators in every home, right? :rofl:

For me, the NanoDLP repaired file failed as the original did.
