oooo i want one!  this can do 4 mil track widths and 5 mil
clearance... it could handle the EOMA68-A20 PCB no problem whatsoever!
 that's 5mil tracks, 5mil clearance.  for the RK3288 however it would
not do the job: that has 0.6mm pin-pitch BGA and eMMC and you need
3mil track widths and 3mil clearance for that....

this is getting really exciting, this 3D printing of PCBs.
