Beginner Slicer Question

Apologies as I'm sure this is a ridiculous question. I've found a few projects that I download from Prusa, and when I open in Prusaslicer they seem to me to be upside down. I've attached a photo, but what I mean is the model is floating with what I would consider the more "flat" side up in the air, which to me would cause me to need more supports than if it were flipped. Now, I can flip it, but I'm wondering if I'm missing something?

Thanks for your time!

I don't think you're missing anything. Unfortunately, some design software doesn't always make it easy to generate parts in the desired orientation, or the designing user may simply be unaware of the issue. For that part, it does look like rotating it 180 degrees so the flat surface is down would be far better for print quality.

Also, watch out for designs that float very slightly. You'll spot these if unexpected support is generated on the first layer.

OK, thank you! I always worry that when flipping it I'm not getting it set to the right height, but I guess if it's green and there is no space under the object, it's correct?

RE: Beginner Slicer Question

There´s a pretty good site for help on the slicer: https://help.prusa3d.com/en/category/prusaslicer_204

Flipping an object which has not already been lifted up manually should always put the object to the bed level (unless the original design has a height set already, which is rather rare I would say.) Green does indicate it´s inside the printer bed perimeter.

Actually it is not a ridiculous question but rather an intelligent question - there´s enough folks not thinking about this and printing things upside down for weeks until we figure out here why none of their prints works out.... 🙂

Cheers
