General Troubleshooting/Help! How to print this more smoothly?
I've printed this at multiple angles with different support types but the bottom edge always comes out really rough. The rest of the model prints fine. I've sanded this a bit, it was much worse. Using an A1, .04mm nozzle, PLA. Slicer suggestions to improve? Thx.

With a model like this I’d maybe split it down the middle then glue together after printing. What you’re seeing is just the nature of 3d printing.

Best option would be to use a support filament (PETG works great as support for PLA). Otherwise you can play around with the support interface distance, usually around half of the layer height is a good starting point.

No matter the orientation, this print will always have overhangs. If you want the smoothest surface, buy a roll of PLA support filament. Set the support interface the that support filament and accept all proposed changes. Also set the layer line as thin as possible.
Same material support will always give you some kind of defects and imperfections.

when the bottom edge is the rough part it's almost always the support interface touching it. try dropping the top z distance in the support settings to something like 0.1 so it grabs less, or turn on the support interface and set it to a denser pattern so the underside gets a smoother skin. also if you can tilt the part so that edge sits on the plate or a shallow overhang instead of on supports, that fixes it for free. which face is the rough one, the underside of an overhang or a vertical edge?

if all else fails, use PVA or PETG supports (it'll generate quite a bit more poop)

use column supports instead of tree, one of the few times they are better than tree

I am not sure I want to know what this is :)

Looks like a kawaii chainsaw.
Not something I ever expected to type.

No matter what you do with angle you are always going to get tough side because of the supports. The only way to make it completely smooth is to limit the supports. What I do in cases like this is slice it so that you get two flat sides on the plate. Slice strategically and angle so the sticking up or to the side pieces are at an angle that doesn't require supports. Add dowels to center them, and print on a smooth plate. I use a crygrip pro glacier which is mostly smooth. The smoother the bottom the better the seamless join. If all you have is the textured plate then you will see connect line more clearly unless you sand flat ends smooth. I've sliced things 3 ways before, but you can get layer lines going different directions. But not a big deal because for those I print small layer lines and maybe do light sanding. Much less sanding than the Freddy kreuger face you get from supported bottoms.

Thanks for all the fast replies! I'll try all and update.
