thanks for the quick reply.
I think I understood your answer for (2), but I would like to confirm it.
so, if I look from above, I would see a blob that's 0.4mm , but if I look from the side, it would be 0.1mm right ? (in here the 0.1 is the layer thickness)
so, if I want 0.1mm precision, I would need to make it on the layer side.
ok, another question about t he width.
the line is 0.4, but if I want to make something & be precise about it, do I need to make it in multiples of it ? or is 0.4 considered the minimum, but I can actually get 0.5 or 0.6 accurately enough ?
also, is it accurate enough to go 0.45 ? or am I starting to get ridiculous :lol:
1) Yes. You would print these pointing up. The Ultimaker can handle some overhang, and thus you can print wormgears like that.
2) PLA schrinks less then ABS, so it's usually better to use PLA. Remember that the printer puts down lines of 0.4mm width and usually 0.1mm thick, so small details can be troublesome.
3) Cura's project planner allows exactly this. I would also advice you to start out with Cura and if that doesn't give you enough quality, then you can always look at NetFabb. NetFabb is a bit harder to use bit give more possibilities to tweak. However, we have had people step back from NetFabb to Cura. Because of the easy of use.
4) Yes, lots of things can be adjusted, and how much infill is added is one of those things. Note that 20% infill (my default) is already very strong. I tried to crush a print by stepping on it today, and I failed. And this was with only 15% infill.
