"Floor" of Part is uh.... Not Smooth?  

RE: "Floor" of Part is uh.... Not Smooth?

What orientation are you printing it on the bed?

If this is the complete part I'm not seeing the need for any supports. 

Please zip your 3mf file and attach it so that we can look at all of your settings.

RE: "Floor" of Part is uh.... Not Smooth?

What he said. Upload the 3mf. Agreed, from the photo it looks like you should be flipping the model on its side. Besides that, maybe insufficent infill density. Maybe the model is slightly tilted and not flat. But without the 3mf, hard to say.

RE: "Floor" of Part is uh.... Not Smooth?

Agreed post the project file 3mf.

Although from what I can see, it appears the pics of the printed parts, the 'top' in the picture looks like it was actually the side that in on the bed as it has a textured surface.  That means their 'flat' surface is actually a very steep overhang and that's exactly what it appears to be.  Its stair stepping but on the bottom.  Without any support in there as that's what they want given their other posts.    Same with the larger rough area across, its a large bridged area with the bottom layers not very well connected.  Either too long or other settings such as bridge flow or the cooling could need adjusting.  Certainly would be better with a bit of support in the middle if they insist on printing in that orientation.

Although unless there's something on the model that we cant see to stop it being rotated 90 degrees, why the hell its being printed in that orientation is a mystery.  Far better to orient it so the 'slot' goes top/bottom.  No supports, no overhangs (that we can see) and the result would be a much better.

I have attached the 3MF zipped - here in the post. Sorry I didn't put it in the other post.  Thank Y'all (Texas speak)..... for your help.

Hhhhhmmmm...... GREAT QUESTION; why did I orient the frame to lay the longer part on the bed, rather than stand it up with the short part on the bed???  I don't know. I don't have a good answer. Perhaps I went about printing it, the way or in the orientation that I modeled it.

I will DEFINITELY try to print it in the other orientation (taller as it sits on the bed), and print without any supports and see what happens.

Again - Thank you!!!

RE: "Floor" of Part is uh.... Not Smooth?

From the 3mf it seems Neophyl's eagle eyes spotted correctly that the model was printed the other way round from the way the model is held in the photos. So yes, that "floor" is an overhang but worse, it's not straight but has a small incline so there's really no way to effectively bridge it.

But clearly, the way to go here is to simply turn the model on its side and print it without any need for supports

RE: "Floor" of Part is uh.... Not Smooth?

Im guessing your 3mf is from your modelling software ?  As it isn't from Prusa Slicer.  It contains no extra information about printer, print or filament settings so we dont know what you are printing like.

For future reference when seeking help and someone asks for a Project file, what they want/need is a Prusa Slicer project file.  Using File>Save Project as from Prusa Slicer will save a 3mf file.  However that 3mf file will also contain the print, filament and printer settings you are using to slice with.  As well as the objects of course.  It also has any modifiers etc you may be using.  It's basically a snapshot of your slice.

Here is a PS 3mf project file with your part to illustrate the best orientation for this particular part.  Printer selected is a basic MK3 as that's what I have but its easy to change the profiles to whatever printer you have.  If you had included a PS project then we could have modified it and further editing wouldn't be needed on your part.

If you aren't even considering the print orientation of your parts then I am not surprised you are having so much trouble printing things.  Application of some basic knowledge goes a long way to getting successful results.  This applies to any printer.

Thank you for the insight there.....   Yes, as you stated, I provided the 3MF from the Fusion 360 CAD software, not the slicer.
