3D printer print speed

Question

3D printers

Friends, help me figure out the speed of printing. Let's say "20 mm per hour" - does this mean that it doesn't matter what area of ​​\u200b\u200bthe object I print, only its height is important?

Well, optional - I'm looking for good arrangements in Moscow to rent a jewelry printer. Does anyone have contacts?

3d printers (if we are talking about extruders) - they print with a molten thread, filling the space with a thread (the thickness of which, by the way, can also vary), usually not 100% (filling level is indicated in the slicer settings, trying to determine the strength of the product). Here is the length of this thread laid out on the substrate (and not entering the extruder from above) and measured.
3d printers, if we are talking about powder (powder is either glued together with ultraviolet light or laser fused) or liquid (liquid is illuminated by a laser or a slice image, layer by layer) - here the layer printing speed almost does not depend on the complexity of the object, respectively, they talk about the time required for printing of this layer plus cooling / hardening (and it can be more than the actual printing).
