After discussion about the layering on my tiny robot printed at 0.05mm layer height, I said I would re-print at 0.025mm layer height and post pics. Here are those pics.
However, first things first – I have only attempted printing at 0.025mm layer height once before and it failed. I have seen other folks commenting they couldn’t get a good adhesion on the base, and therefore the whole print would remain in the resin. This is the same thing that happened to me. I forgot this when I went to print the robot at 0.025mm and sure enough it didn’t adhere but half-way through I caught it and I stopped it.
I wasn’t sure what to do, and I don’t recall if there was a solution on this forum, but I decided to see what would happen if I opted to print it at 0.025mm with the GRAY resin profile. I figured that with the colorant, it might need a slightly longer exposure time and this might help adhesion. I got it going and had to leave for a short day trip over to the beach with the wife.
When I got back – it worked! And it’s amazing. This is what you want, this is what you get.
You can see a little bit of banding in the pics, but they are almost imperceptible to the naked eye. You may also notice he has a little bit of hair on his chest - he flipped over on the paper towel I was carrying him on and got a bit of lint. I haven’t re-cleaned him yet; I’ll do that after I remove the supports.
@Question - thanks, it was a quick 10 minute design in Blender… Some cubes and isospheres.
@Christopher - The good macro lens we have has a super-narrow DOF. We have another one that will be wider DOF, but not as macro. I will try both for future to give a better idea of size and overall quality.
@christopher Bokeh is actuallythe character of defocused areas, not the amount of defocus. For example, a defocused point can have a donut-shaped ring, an evenly shaded disk, or a bright center that falls off to darkness.
