I'm very new to SLA printing (and all 3D printing really), and I've been trying various resins.
One thing they all seem to have in common is that even after curing for 10-15 minutes under a 6w (marketed as effectively 60w) UV light at close range on a turntable, in a UV-reflective grow tent, they remain sort of 'sticky'. Enough so to gain textured fingerprints if squeezed slightly. Is that normal? Is that indicative of the parts not actually being cured, or...? They don't appear to be actually wet even though they feel sort of wet.
Also, after washing (I've tried 99% IPA manually and Mean Green in an ultrasonic for 8 minutes on different prints), it seems like the prints always have some slick substance on them, which I assume is resin (if it was one of the cleaning agents I assume it would rapidly evaporate and not be so 'slick')... so what am I doing wrong?
