No, but the answer could depends on how you set up the lead screws, what kind of lead screws are used and how they connect to the stepper. Also it is important how you transfer the linear Z motion into the X gantry. Note that regularly used TR08 (Trapezoid, 8 mm) lead screws are stiff enough to not flex under the limited load of an X gantry. So, putting them ...

The motor is mounted in a fixed position no matter if it's on top or bottom. You can imagine the lead screw as a rod hanging down and supporting the bed in the Z direction only, because all of the XY rigidity comes from the Liner rails the bed is attached to it works just as well if the stiff rod is under compression instead of hanging from the rod. Any ...

I was wondering the other day why don't all three motors move at the same time? That is perfectly possible for most printers (with limitations, "3D Printing" with all steppers being used is called "non-planar" printing), but there are some major cons you need to deal with. First, there are not that many software suites that slice objects ...

Frame challenge: is it just 1D printing? Each G1 command moves linearly in a single one dimensional affine subspace of the build volume. What makes 3D printing 3D is that the resulting object produced is three dimensional. There are indeed a lot of advances to be made in FDM printing by not working only within constant-Z cross sections at a time, but these ...

The Z axis moves between each layer so you are indeed printing in the 3rd dimension. There are some techniques that move all three axis at the same time.
