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
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.
