Hello,
I got my part as
By using default 0.2 standard profile, it shown to have some ‘gap’ at outter wall as:
Tried to change Wall generator from Classic to Arachne but no success so far. Tried to slice with Cura, showing no gap/hole like that.
Please kindly help me to fix this.
Thanks!
The recess is not leaving enough wall and will need to be beefed up around that chamfer. Maybe you could try a thinner line width like 0.38mm on the outside, but I’m pretty sure you’ll need to edit the file in the end as it’ll probably blow out in printing.
Did you try to enable “thin walls” with the default wall generator. It’s the setting just underneath the wall count
Hi,
Yes, I tried to apply ‘detect thin wall’ with all other parameters are default, but still the same. 
I tried to decrease outer wall to 0.3, but so far, still the same.
In the end, I tried: ‘detect thin wall’, ‘wall generator to arachne’, use smaller nozzle (0.2)… but got no sucess so far.
Only when I tried to use slicing mode to ‘close holes’, then my part became a good solid one, which is useless.
All depending on the model use, if it doesn’t hurt the use I’d add a right click part “torus” and resize/position over that area and assemble. It might need one or two but I think you could give a little bulge there (again if the model is able to function the same).
That’s just because your part has thinner walls than the filament line width.
E.g. Impossible to print a 0.1mm wall with a 0.4mm line width.
You’ve to redesign your part or to use a 0.2mm nozzle to expect to have at least one wall.
Thank you for your tips. I’m just confused as CURA doesn’t slice that way, so I thought there’s some parameter in Bambu studio that could change to achieve the same result.
Everyone who responded here pointed you in the right direction. You’re asking too much of the technology and the laws of physics are very unforgiving.
I can see what you’re trying to do. You want to place a 5mm magnet inside a plug. You’re trying to build a 9.4x9.4x10.7mm part using a resolution that simply does not support that level of detail. Even if you were able to get your part to print, I can promise you that a part that size will simply break apart the moment you try to place it inside the hole you’ve built it for.
To illustrate this in CAD, this illustration below shows what it looks like. Your 5mm magnet box is placed inside a 9.4mm circle, leaving a corner material thickness of 1.165mm. Now, note that this is at the top of your plug, and, of course, the barrel is tapered, I’d guess by the image by as much as 1mm. It doesn’t take a lot of imagination to realize that this simply won’t slice without leaving holes, but even if it did, you wouldn’t have enough material to provide any strength.
There is a saying I often hear used when manufacturing engineers talk to mechanical engineers: ‘Just because you can draw a pretty picture in CAD, doesn’t mean it can be built in the real world.’ Those words ring truest in the 3D FDM printing world. As a society, we have become so accustomed to the WYSIWYG Desktop Publishing world of the last 40 years that we often forget the basics; pixels are easy, but the real world is unforgiving. Consider this an education in that very real-world fact.
That’s a long-winded way of saying: you can’t do what you’re trying to do with FDM. You may be able to do it with resin technology, given that resin has much higher resolution, but forget about filament; it just ain’t gonna happen. Sorry for the blunt answer but it is what it is.
Thanks, it’s more than enough for me to understand. As I didn’t own the part so all I can do is compare between 2 slicer software and saw the different.
Best regards, 
Show us how Cura slice it, and link to the model.
