I’m printing a build platform chock full of max detail level earrings in the purple castable resin. Printing time is estimated at about 33 hours. There are 1843 layers in the print and I’m using default supports for each earring.
It turns out that about the first 250 or so layers are 100% supports. I don’t need them to be super finely detailed. After all, I’m going to remove them and throw them away!
Now, I understand that for technical reasons, everything printed on the same layer has to be the same thickness.
But is there any technical reason why the first layers, which are 100% devoted to supports, couldn’t be printed at draft resolution, with the more detailed print resolution starting say 10 layers before it’s needed?
The slicer software would need to be smart enough to know the difference between a support and a printed object I designed – and it already knows that!
It would have to be smart enough to know that (with me making up numbers just for illustration purposes), that one 100 micron layer is four times as tall as a 25 micron layer, so for that first 240 layers, it would only need to print 60 100 micron layers, then switch to 25 micron layers afterwards.
It seems to me that in this example, we would save on the time to print 180 layers, or about 10% of the print time would be shaved off with a fairly simple software improvement.
Or is it already doing that?
