X-axis is ofren caled X-axis assembly or portal/cantilever ; Y-axis is usually the Y-axis assembly or Bed-movement ; This does not work for a CoreXY, where X and Y are called the "Horizontal" and Z the Bed-movement.

<p>How do you call the mechanism that allows linear motion along the Z-axis in a Cartesian 3D Printer? </p>

<p><a href="https://i.sstatic.net/jJetV.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/jJetV.jpg" alt="enter image description here"></a></p>

<p>I know what the individual parts are; it is a lead screw, a smooth rod ... but how do you call the mechanism that allows this linear motion?</p>

<p>Mechanism is defined as: an assembly of moving parts performing a complete functional motion, often being part of a large machine</p>

<p>So I guess, it has to have a name, doesn't? .. but I am unable to find it</p>

I would go with "z-axis mechanism". Not everything has one word for its name.

I would like to analyze it .. I think it is possible to do that with Kinematics .. But I am not sure where do I start .. Maybe in the Math or Physics Stack Overflow, but first I would like to have an idea of what to do ..

I would suggest "z-axis assembly" to refer to the collection of all the parts that contribute to z-axis motion/stability.

So, I would go the same with the "x-axis assembly" and "y-axis assembly" .. I don't know ..
