What are main differences between rafts, skirts and brims?

I would like to understand the differences between rafts, skirts and brims. They appear in the software which I'm using to edit my 3D objects. Can anybody elaborate what are these and what are the main differences between them?

What exactly does automatic bed leveling do?

I get the concept of automatic bed leveling...the printer moves around the bed and uses a sensor to identify high and low spots, then "software compensates for differences". But what exactly does "compensates" mean? It is extruding more material…

Raft hard to remove?

I've been having a hard time lately getting the raft off of my ABS prints. Is that a symptom of either a nozzle or bed that are too hot? Or is there some other factor I should be looking in to? I have an UP mini that I've modified both the nozzle…

How should I go about printing easily removable rafts?

I have had a 3d printer for a while now, and I have a lot of the quality settings dialed in pretty well, but one thing that constantly bugs me is removing the raft from my finished prints. I am using Repetier and I have set the air gap to 0.2 mm.…

What tweaks do slicers use to get rafts to stick?

I've always had trouble getting prints to stick directly on my bed, but had great reliability when use rafts. This didn't present a problem when I was using PLA, but I recently got a roll of PETG and it is very hard to remove rafts, so I am once…

I'm experimenting with my new Ender 3 V2 using PETG filament on the textured side of the included glass bed without any additional adhesives. I'm been having trouble with adhesion until I found out that enabling raft on my prints helps solve the…

When to use Wave Bonding vs Raft on a 3D print?

I use a Micro3D printer, running on OctoPi (yay!) (although this question should be relevant to any 3D printer that offers these features) and have options for raft and wave bonding. Are there best case scenarios for when it is appropriate to use…

I'm trying to build an assembly with one larger part (about 50 mm x 50 mm), two small parts (about 10 mm x 5 mm) each, and one part that starts with two 2 mm x 2 mm squares that eventually bridge into a sort of flap. The larger part has decent…

Usually I had problems with the adhesion of the first layers, and most questions here and out there are about this issue. Instead now I'm facing another problem. After "some" (few or even after 10h) suddenly the filament does not stick anymore to…

Alternative raft generation

For some recent prints I have been using rafts as generated by Cura to aid in bed adhesion; which helps, but is not as reliable as I'd like it to. However, it seems to me that the raft generation could be so much better; if I explain what I have in…
