So I am still deciding on which 3d printer I am going to purchase and I came across one that is new and being manufactured in the USA called the Copperhead printer.
Copperhead positioning precision is x/y =11.7 microns, z axis= 2 microns.
Ultimaker 2 positioning precision precision of x/y = 12.5 microns, z axis= 5 microns.
Ultimaker 2 prints much faster though, the link below shows the stats the American company claims for its Copperhead printer.

Does this mean the Copperhead 3d printer will have better printing resolution than the Ultimaker 2 or are their more variables that account for print resolution?
