Do you like rafts on prints
Yes and no. There are points where they’re great. Other times, it’s best to leave them off.
I have tried rafts but have only had problems with them. However I do print brims for prints which is like a side step raft.
^— agreed, mixed bag. Only need them for certain models. Your vote needs 3rd party
I can only think of one or two times it helped, and even then, it could have been avoided by just making some tweaks to the model.
Depends on the material. For PLA, nope. For PET-G, Nylon, PC. Yes.
I almost never use rafts. Usually just a brim and some hairspray if I run into trouble.
they serve a purpose, it’s not always needed. Its not a like/dislike situation. Do you like using a fork to eat? What about for eating soup?
Like them? no - but they can be wildly useful in very limited cases.
as soon as you start printing with nozzles smaller than 0.2 you are going to love raft 
@Rene_Jurack why would that make a difference? If anything I would think rafts would be better with larger nozzle sizes
Only if Im in the water
@Adam_Steinmark did you ever try to get adhesion with a 0.1mm track?
@Rene_Jurack No I’ve never had the need for such precision. If your bed leveling is accurate enough you should’t really have adhesion problems. I guess if you use a lot of ABS it could cause lifting if your bed doesn’t heat evenly enough or get hot enough. Then you would just have to worry about de-lamination but a raft wouldn’t help with that. What do you print onto?
I wouldn’t know how to identify a print for which a raft would help. Lots of tiny points of contact, maybe? Even then, I’d use a brim. I’ve had bad luck with rafts fusing to prints on multiple printers and stopped using them a long time ago.
@Aric_Norine The problem isn’t the height but the X/Y thickness. You can think of a 0.1mm nozzle as laying down a cylindrical line; there is a small amount of squashing but it pretty much means the smaller the nozzle, the less contact to the build plate or previous layer. This of course can be augmented by increasing flow/extrusion rate. Additionally with a smaller nozzle you have more lines per layer and if you print ABS it’s just more opportunity for the shrinking due to cooling to cause lifting or de-lamination. This isn’t as dramatic as it sounds, in fact the difference should be minimal but it really depends on the slicing software automatically making these adjustments.
@Aric_Norine That’s some impressive slicing software, I’ve been meaning to purchase myself a license and that kinda reaffirms my decision. I guess if the software can comply that well you could theoretically print a line as wide as the outer diameter of the nozzle tip assuming it’s flat. Anything wider would cause the melted plastic to curl around the nozzle and cause untold issues.
