Downscaling 32mm minis to 15mm Mar 6, 2022 21:51:18 GMT

Hi all, i'd like to downscale some recently acquired mummified undead stl files. Opening chitubox show the mini as roughly 32mm. I Know how to downscale to 15mm but i dont know whether i should change the printing parameters. I'm aware of the recommended
settings for 32mm ( i'v got an elegoo mars 3) but i'm
not sure i should keep them when printing 15mm minis.
Any help would be welcome.
p.s: the settings were:
For normal layers:
Layer thickness : 50 um
Light-off delay : 3.1 sec
Exposure time : 3.1 sec
Lift after print : 7 mm

Thanks

You shouldn't have to change your printer settings just because you downscaled your minis unless you also want to print at a thinner layer height. I'd be more worried about if the presupports were still good after shrinking them down.

That said, your exposure values seem high. I also use a Mars 3 and my 50um exposure time is 2.0 sec for Syratech Navy Grey. Most other resins I've used are close to that.

I upscale 10mm minis (Forest Dragon Patreon) to 15mm and print at 20um, 1.4 sec exposure time.
