Rafts: Rafts are a few layers of plastic a placed on the printing surface before the object is printed. If non water dissoluble filament is used, a bit of an air gap will be placed between the raft and the print itself so it can be removed easily. A raft can help a print stick to the printing surface as it normally has a larger surface area than the bottom ...

A raft will allow for better adhesion for the whole print as the raft attaches to the printing surface and the print attaches to the raft. Rafts go all the way under the print and consist of multiple layers, whereas a brim is only 1 layer and on the outside of the print. Rafts are normally harder to remove than brims because of the increased contact with the ...

A raft is used to prevent warping. Instead of printing directly on the build surface, parts are built on top of it. You remove and dispose of a raft post-print. The raft is larger than the part and so has more adhesion. Rafts are primarily used with ABS to help with bed adhesion. Rafts are also used to help stabilize models with small footprints (e.g. a pole)...

All three of these features are used to improve the quality and success rate of prints, especially those failing due to issues on the first few layers, or due to the small size of the first layer. Raft A raft is a horizontal feature made as the first few layers of a print, and is used to help with bed adhesion issues, primarily used with ABS. The first few ...

A raft helps when the part has few points of contact with the print bed, and doesn't therefore adhere well at points within and without the part. A brim helps when the part doesn't adhere well around the perimeter of the part. There are very rare situations where you'll need both, but typically you'll only use one or the other.

In the newest version of Cura (4.5.0), in the per model settings, the only thing you can change for options set Build Plate Adhesion is Brim Distance. What this allows you to do however is create a brim for everything with the distance of a millimeter or two, and then for the part that needs the brim, you just set the distance to zero in the individual part ...

This is a "No" and "Yes" answer, it depends on the version of Cura you are using! No, there are no options available to set the brim to some of the parts in Ultimaker Cura (at the time of writing this answer, pre Cura 4.5.0). You could however change the smaller model to include the brim in your design, or add so-called "Mouse Ears&...

I don't know a way to do that with Cura without breaking it up into multiple parts with different settings for each, but what about just enabling supports? You'd only get a very small amount of support material and it would act similarly to a brim to keep the small part from detaching.

When there's a cut in the outer ring (the manual skirt), Slic3r will fill the area as expected:

This post is quite old, but I describe how I solved this for anyone has the same problem I had: areas moved by the nozzle as the base of some appendices are too thin and tall. In Cura 4.8 (I don't know since which version this feature is available) it is possible to add some custom shapes (cubes or cylinders) to your model. You can find this tool after move, ...
