I just started messing around with ASA on my i3 clone (Monoprice maker select plus aka wanhao i3 plus) while printing parte for my 2.4. I did make a cardboard enclosure for my printer and had to reprint my bed thumbscrews and cooler in ASA, but otherwise it pretty well. I treated it the exact same as PETG, other than bumping temps. I was honestly pretty surprised. Yeah, the prints aren’t perfect, but I also spent zero time tuning the printer for ASA beyond a PID tune.
Not OP, and this thread is three weeks old, but I would estimate somewhere around 20-40 hours for your first build. I’ve been… very slowly… working on my 2.4 for just about the past two months. But most days I don’t work on it at all and when I do I’m lucky to get 1.5 hours of time.
I’ve basically completed assembly, other than attaching the panels. On the to-do list are tensioning belts, setting up my klipper, and then tuning.
If you have the time, and an all metal hot end, you can also print your parts on basically any printer. I printed mine on a reasonably stock i3 clone.
