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.
