I am in the process of builiding a wallace with a print surface of 2ft by 2ft to print parts for the r2builder's club. My question is if I were to print a 18in diamater hollow dome, when it got to printing the top would it fall in on itself or would it print correctly.
That would depend on how steep the dome is. Angles up to 45 degrees are printable without support, if you need flatter angles, you would need support material, which can be removed after the print.
