Yep, the render is from KiCad, although I had to make a couple of parts in Wings3D that are missing from the core library.
Main problem with the inkjet seems to be that the whole process relies on the ink wicking slightly in the paper, so on acetate that doesn’t happen. You get this sort of spotty effect where it’s all black, but there are ‘peaks’ of blackness at the centre of each spot. Haven’t tried the inkjet on the tracing paper yet.
