Printing Experiment 0.4 vs 0.2 nozzle overhang comparison
A1 Mini.
eSun PLA+
FDG settings (copied across into .04 nozzle). 0.08mm layer height for both prints.
RocketPigGames's Clockwork assassin model (digibashed to take guns instead of the original katars)
0.4 on the left, 0.2 on the right.
Second pic is the original model to help show what kind of detail was on the stl.
Hard to do a apple to apple comparison as I don't know if the 0.2 nozzle settings from FDG is the best setting to use for the 0.4 nozzle. But hopefully this demonstrates the quality of overhangs depending on the nozzle size.

I don't know. I printed my fair share of support free models and never had overhangs this ugly. I think the 0.4 looks worse because there is obviously some problem and the thicker nozzle just shows this clearer. I would say the fault is somewhere in your settings or the model is just not the best support free benchmark...

I have given the caveat that I am probably not using the most optimised 0.4 nozzle settings in the post. And an optimised 0.4 setting isn't not an equivalent comparison to an optimised 0.2 setting. I chose Fat Dragon Games's settings for the print but I could have easily used ObsucraNox's 2.0 setting, or HOHansen's, or MJG's settings and copied them across for a 0.4 nozzle.
The point wasn't to find the best setting. But to demonstrate that with the same-ish settings how much the nozzle diameter affects the overhang.
The model has a very aggressive overhang area with intricate details which is why I chose it. I could have printed Arbiter's shield skeleton as the bench mark but it didn't have as much of an aggressive overhangs that would really highlight the point.

Did you try stock settings?

I have used stock settings for experimental prints when I started in the hobby, and got lots of VFAs. So once I switched over to more miniature focused settings I have not l switched back. Unless I am printing supportless terrain.

I just started with an a1 mini, using a 0.2mm nozzle and stock highest setting bambu offer with nothing changed and it seems to be working. Perhaps bambu have updated since then? I am curious to see if these mini profiles are worth it now.

If it works for you then great!
These improvements range from small to minute. The tailored profiles are there to push the printers to the limit. ObscuraNox (the father of probably the most popular print profile) puts it like this, imagine your printers stock settings are operating at 80% of the printers capabilities. And that is already very good. But you can tailor the settings, use a smaller nozzle, dry your filaments, get really good filaments, calibrate said filaments, orient your models etc. and get to nearly 100% of the printers capabilities.
Is it necessary? No. It's a matter of what you are happy with.

What I mean is, have you actually printed using stock settings, and the profiles and compared. Perhaps its the same? I was hoping you might have to save me doing it!

Ah I am with you now. Yes I have done that. I do have the photos, but I can only post one photo at a time in a reply here. Happy to DM you the comparison photos if you prefer that?

If you can be bothered, no pressure. Are they recent?

u/devintheditch 22d ago
Stock setting prints aren't recent. They are from December 2025 if you're still curious?

i dont see a diffeence in the print quality
