I found this desktop 3D printed robot, the BCN3D Moveo. I think I might give this a try.

Can I use PLA or a modified PLA? Would it be strong enough?
What tip size would you recommend for a print like this?
What layer height would you recommend?
Cheers!

I use Fusion360 and export the models as STL.
Is there a better file format to use? Or are there export setting I need to use or check for?

I'm on Cura 5.3.1 trying to slice a prop. I'm setup to print two walls and 10% infill with a 0.8mm nozzle.
In Fusion360 I pre-shelled the prop to 1.6mm wall thickness. If I slice with infill the entire interior void infills and the bottom thread detail is omitted. If infill is off I get the proper shell but still no bottom thread detail.
I've sliced/printed a similar design before without issue.
Any idea what setting could cause this? Or perhaps something in the CAD model?

I'm running the Ender 3 S1 with std hot end and a 0.8mm nozzle. I've printed a number of temperature towers with PLA and PETG, different filament manufactures.
In both cases the results point to a lower optimized print temperature than the filament minimum recommendation. My understanding from what i read was typically with larger nozzles you usually increase temp 5-10%, not decrease.
Anyone else experience this?

This method (splicing files) would leave a seam on the top few layers. I think I'd print two parts and glue them together.
Ya, that's what I thinking. I've even contemplated using a 3D Pen to fill in the defect.
I'm learning layer height plays a big part, I was trying for 0.6mm. Pictured is a pure spiral/vase mode with PETG at .28mm layer. The hole left behind is ~ 4mm. If only I can get that to fill over.

I never noticed that and I don't know the answer. When you say "much wider" how much wider are we really talking about?
Maybe @MariMakes or @Dustin has some thoughts on this?
It was maybe 1/2 width offsett, noticeable. I don't know if it is a bug, probably operator error.

I made a small test piece ~60 slices starting with spiral transiting to conventional. I made a couple test prints and I noticed the conventional print at the same Z height printed much wider than the spiral. Does one method print on center and the other inside or outside? Is there a adjustment or correction in Cura?
-
Yes, that top part when it goes more horizontal it fails. I've been typing to manually edit for some mixed mode printing, spiralize and finish conventional perhaps with some infill??
Still riding the steep part of the learning curve.

Here is the project file. I assume the model is comes with it?
-
Applying Vase mode in the slicer I'm seeing a seam in the preview. I assumed vase mode does no have a seam. Is there a setting in Cura that overrides or modifies Vase mode that is causing the seam? I've even saw the seam in a printed part.
I'm using v4.13.1

I'm printing an over sized C9 light bulb prop in vase/spiral mode and the very tip is not filling in properly.
1) What would you recommend so the tip properly fills in?
I'm thinking maybe print "normal mode" for a base, switch to Vase/Spiral, then back to normal mode to fill in the tip.
2) Is this possible in Cura?
If not I might have to manually edit the gcode.
3) With an Ender 3 S1 and Merlin can I switch mid print to relative extrusion?
Math is hard and this would make gcode editing simpler.

That's probably what I'm going to do. I was surprised at all the builds and blogs for this print/model I could find but none remarked what print settings were used.
This should be interesting.
