Resin slicing orientation

[restive lily]

This my first time using a resin printer. I was planning to do this dino as a test print. Has anyone got any tips for a suitable orientation, and where to put a drainage hole? I feel like the supports would leave less of an impact on his legs/belly, but if I flip him around for that, then would the drainage hole need to be on his back? 🦕

this didn't end up working. a small rectangle ended up stuck to the film itself, and nothing was left stuck to the build plate. unfortunately I forgot to take a picture (too busy dealing with all of the resin I spilled when trying to pour it back into the bottle).

these are my settings - taken from the 'BEFORE POSTING' sticky, but with lift speed a bit slower as per the elegoo setting sheet for this resin: https://docs.google.com/spreadsheets/d/14R1cGB1-OxLteH79fH0lgn85j9g45iooQzL8hPbbVJk/edit?pli=1#gid=669571052

I'm using an Elegoo Saturn 3 Ultra, with 'Elegoo ABS-Like 2.0 resin grey'

and I had the model quite small

is there something obvious that I did wrong?

Do you level the bed well?

[restive lily]

Probably not, I think I might have overdone it actually and had it too low. I'll recalibrate and try again today when the temperature hits 22 degrees as well

OK

for drain holes, to combat the suction cup force created from hollowing you need to place one at the bottom and top of the hollowed profile

[restive lily]

do you just glue a circle of resin back in at the end to conceal it?

[visual ruin]

yeah check the box that creates a plug when you create the hole

[restive lily]

great, thank you

after re-levelling the bed, and printing when ambient temperature was better, I got my first successful print - a tiny dino

oh wow, it's tiny lol, I probably would of just printed it solid, but that was good practice
