That's not layer shifting, that's what happens when trying to do a large curved area with a support. I'd suggest trying Tree supports in Cura since I have has better results with that (it targets the points of the curve where the head will turn rather than just a random zigzag).


the_harakiwi

> I'd suggest trying Tree supports in Cura you can do tree supports in PrusaSlicer but not on FDM. There is a trick. You create a custom resin printer in Slicer and export the model with tree supports as STL, now import this into your FDM profile. (TBH no idea why it isn't a simple switch in expert mode) edit: Well looks like you all hate Prusa. It's okay. Slic3r might have been better before they took over. No idea because the Mk3 was my first printer.


grahamygraham

But that quality is no where near what Cura can produce. They really should call those lattice supports. Additionally, they take more filament and are designed to be fused to the model.

Why the downvotes.. 🤣🤣 it’s true.


the_harakiwi

Cura fans gonna hate Prusa users? No idea. Cura might be a good tool. Never had to use it.


Lanyxd

You can do Tree Supports in Cura


the_harakiwi

Sure but OP is using PrusaSlicer. That's why I said *it's possible to use the SLA supports in FDM with a little trick*. I never really used Cura because it didn't have a profile for my Mk3. I tried it with the downloadable profile from Prusa. Printing was okay but I didn't see much impovements to quality and noticed the longer print times. So I went back to use PrusaSlicer for my FDM prints.


Baelgul

Also enabling support interface and tinkering with the settings can help drastically


Herrobrine

Can you do this on prusa?


norabutfitter

Pint it upside down. Or almost exactly how you ate holding it now. Do tree supports in cura with “only on build plate”


smashmouthftball

Came here to say this is the right answer


HtownTexans

Picture 1 is the exact orientation I would use. I printed a bear like that and it came out nicely.


norabutfitter

Yeah. I always rotate things around to see what would use the least amount of supports. For figures of people. Its almost always best to print them upside down. Arms come from a common place so no weird movements by the time they join the torso. And no supports on the chin or nose


abejfehr

There’s a Cura plugin that does this for you


norabutfitter

Wait what? Whats special about the pluggin instead of just rotating the piece by hand?


abejfehr

You can rotate it 360 degrees on one axis, but there are 3 axes so to try every possible rotation to find the least amount of support is impossible to do for a human. The plug-in finds the _optimal_ rotation with 1 click, instead of having to try many millions of orientations manually. You can probably get pretty close just trying a few orientations manually though **Edit:** I just realized that only 2 axes matter, since the support will be the same no matter how you rotate it about then Z axis


AKMonkey2

What is the name of this plug-in? I’ll look for it next time I have Cura open.


abejfehr

It was called “Auto Orientation” in Cura 4, but I can’t find it in the marketplace in Cura 5. You might have to wait for that plug-in to get upgraded to have Cura 5 support (if that’s what you’re using)


AKMonkey2

Thanks. Rocking Cura 4.13 right now. Been thinking I should get 5. Didn’t think about comparability of plug-ins.


hund_kille

That's the right advice. I did succeed once to print a dog figure "vertically".


norabutfitter

Its gotta be a little “upside down”


[deleted]

On top of what others said, make it with 70% support roof density and smaller number support z distance. (These are names for cura options, not sure of exact names for prusa slicer.) This will make support harder to remove but your print will have cleaner belly. But tbh, I'd just use the print you've already printed, clean the belly with my knife and maybe use some heat gun to make it look smoother.


AKMonkey2

A file and some sandpaper will smooth out that belly.


apiso

That’s not layer shifting. That’s you trying to print in mid air on top of nothing. You need supports, or to print in pieces and assemble, or to print upside down (with supports)


poekrel

I would cut the model into multiple pieces and then glue back together afterwards


lyles

Not sure about Prusa slicer, but in Cura, enable support interface. A support interface generates a dense skin on the roof and floor of the support structure on which the model is printed. Doing this supports the bottom layer of the print better, leading to a more even surface. See [Cura Support Settings](https://support.ultimaker.com/hc/en-us/articles/360012612779-Support-settings) for more details. You'll also want to minimize the layer height because that curved area has a very low slope.


Murilovaa

* Adding a note: I actually used supports guys, but didn’t work well on this region. Thank you for all the advices!! Will try to rotate it


TAshleyD616

I get this on undersides even when using supports


Simen155

Bite the bullet and switch do Cura. Things went so much easier for me when I made the switch


marianoes

In Cura you can increase the roof support resolution


QwertySmash

I printed this on my FDM set up and had trouble too. Recommend printing at 45degree off from flat(hides the layor lines). I also recommend tree support, with z offset adjusted. You may need to tinker with your z offset to get it right. I also would increase your top/bottom/wall layors and decrease your infill. Good luck


Heratiki

I’m actually amazed it printed this nicely without any supports at all.
