I mostly print PLA so the lid is propped open and the door is ajar… Once winter comes to the midwest and my basement is freezing cold I may have to adjust things a bit. I added a Prusa MINI in January 2022 and could not print properly until I added an enclosure.
I have a Prusa MINI and used Prusa i3 machines where I used to work. They are pretty solid, and I do like their open source ideals quite a bit. But I needed/wanted a larger print area for a price under $1,000 USD and the Bambu fit the bill.
