20x20x20 calibration cube size change after switching filament

I used to print with PLA and everything in my printer was calibrated. But I got a new type of filament called Poly Hybrid from a friend of mine. When I print a 20 mm cube, the x and y axes are fine but z axis in cube is about 18 mm.
Should I calibrate my printer z axis again for this new filament type? Because I couldn't find any option in Slic3r in filament tab to set layer height.

Have you measured your filament, with calipers, at several locations, and compared this to readings from the other filament?

@Davo Yes I measured new filament diameter in first 1 meter and it was exactly 1.75 mm. But i didn't do it for my previous filament. OMG I calibrated my printer with previous one

@profesor79 Good call, maybe the OP can add an image of the print as well!

Either your drivers miss a step, your axis connectors are loose or your steps/mm config is faulty.

Filament type should have nothing to do with the issues you are facing. This is a mechanical issue or a slicing/scaling issue. The hotend should, if instructed to go to 20 mm height actually go to 20 mm (it did do that before!), it cannot "lose" 2 mm on the way up unless you have a lot of lost steps (e.g. too much load on the carriage pressing it down, but that seems pretty unlikely). Typical variations for Z are in the order of a few tenths of a mm for a properly dialed in printer.
Please note that the Z axis is usually controlled by a leadscrew (your printer type and brand is not known, but if you have a Prusa style printer or some sort of a cube you'll have a leadscrew, Delta's have belts), so once you dialed this in, the head will go to the instructed height.
Reasoning to your observations: If it was under-extrusion because of lower diameter filament, the last few layers should have been falling out of the hotend (considering the head goes to 20 mm and the print is 18 mm high). This is not the case; you have not described that kind of behavior.
The most likely problem is a slicing or scaling problem.
The answer to your question is therefore: "No you do not need to calibrate the Z height.". But when changing to another filament you could calibrate the extruder for this new filament; if the diameter is not far off you do not need to do that, but you could if you are into details.
Preferably questions like these need to include a picture of the print and the printer type!
