I am not too familiar with Cura, but I don't think they have the 'support painting' feature of prusaslicer and the likes that would allow this. In those, you can paint where you'd like your support to touch or use modifier meshes to selectively add regions that should be supported. It's the easiest way I know, though I have heard that Meshmixer also used to be able to do that.. but I've never tried.

Check if your print is wobbling when it reaches that height. If it does, you may need to add support to fix that - a few organic support touch points halfway up should help

On top of some of the other tips, layer height being the most prominent, perhaps try a different soap or clean it with alcohol after. I've noticed a difference between soaps (and even between toilet paper brands) - some things leave a bit of residu I think.

My condolences

There's no data on those, but we did at some point print air tight (0.8 bar over a week iirc, no vapour smoothing) in abs, so it may be similar. Consumer grade hardware of this sort is probably still pretty far away, but it's not as impossible as many believe :)a

I agree with all your points, except the last one. Admittedly, it is still rare, but there are companies out there that, using industrial machines, manage to get close to or (in case of the linked one) exceed injection moulding in tensile strength, and are achieving near isotropy using FDM processes. https://orion-am.com/blog/orion-am-news-1/3d-printing-peek-stronger-than-injection-molding-12

Disclaimer: I work there. However, this article has independent test data that has been verified by 3 different labs by now.

Interesting, thanks for the insight!

I'm not well versed in this at all, but would this also work if the "attacker" were to take a screenshot of the image they wanted to alter, and plug that into an AI tool? It sounds more like metadata tweaking from the article, which would be bypassed by a screenshot.

I was in this camp but find that the results I've gotten from DDG have been notably worse for the last year or so, to the point that I don't expect useful results to come out of it any more at this point. Even if I searched "site name" because I couldn't remember the URL was spelled "site-name.com" I've had no results coming from DDG, while Google had it as the first hit.

Have you experienced something similar? Are there techniques or workarounds I'm not aware of?
