I guess it depends on each of our experiences. Initially I had several issues with FDM but after learning how to deal with them, I have few now. Used mirror for the base, sprayed it with cheap hairspray, level the base properly and no issues after.
With my Elegoo Mars, I have had problems right off the bat. Levelled the print surface, and still had issues. Lubricated the film and still had delamination issues. Repositioned the object so that I have more bed contact, and a successful print. Print the same object again and more delamination issues. I switch resins, and have worse luck and have to play with exposure settings.
I hope to get to the point that I will eventually know exactly how to prep my Mars for a perfect print every time.
Still, I love my Creality CR10S and would never give it up. I also would love to get a new Saturn. For me, I need both types of printers for what I do.
