Printing super small prints

[t-squareddesign 2]

I'm looking to print a small item that is 4mm x 4mm x 1mm

 

I'm going to print it in Ultimaker brand PP

 

What advanced printer settings must I configure before running a print?

I imagine a slow print speed, correct?

I'm also using an AA extruder. Should I use something else?

Lower layer height? But ideally a smaller nozzle would be used.

Layer height is the Z resolution.  Line Width is the XY resolution.

Print speed is important but you will be hitting "Minimum Layer Time" and so that will limit the print speed to whatever you have set for a minimum.

It might be more advantageous to print 3 or 4 at once.  That would allow the printer to maintain something closer to "Print Speed" and allow each of those little models more time to cool.  Printing a single model at very low layer height would be tougher to adjust the speed, which determines the flow rate of plastic through the nozzle, and consequently the "nozzle pressure" would be very low.  Your flow rate would be in the neighborhood of 1/10's of a mm³/sec.  I'm not a Ultimaker guy but that would seem to be a tough rate to control accurately.
