Using the standard print settings, the cured traces are between 70-80 um thick (0.07-0.08 mm), with a sheet resistance of 12 mOhm. 1oz of copper is about 1.4 mils (~35 um) thick, with sheet resistance of 0.5 mOhm.
If you check out our user guide on circuit design suggestions, we have two charts which may help you determine how much ink you should lay down for your application - I've included them below.
The first plot shows the current carrying capacity of the ink at various tracewidths, based on the peak temperature of the trace, at the standard ink height/thickness:
The second plot shows the conductive ink sheet resistance vs. the ink height/thickness, in um. The default print height is 100 um, which leads to a cured ink height/thickness of 80 um - this is useful if you are planning on printing at different heights (configured through the advanced settings):
If you are trying to use the conductive ink for higher current applications, you can try to tin your traces with solder. I'd recommend checking out our hand soldering guide for tips on tinning your pads / traces.
Hopefully that helps!
