Hello i'm Maik and i own an Ultimaker 3 Extended.
Fine print results are essential for me. That's why i only use the best slicer "Simplify3D" for all print orders and a max. layer height of 0.150mm. If your STL file is very detailed i'll use 0.100mm or even finer settings.
If you need another color or material feel free to send me an email.
