Though I didn't think there was enything really wrong with the resin, as the reason for failure with this print was a definitive lack of supports for the size of the print, and I've seen pictures of resin in UV light that wouldn't glow.īut after heavily redoing the supports the same print failed again and this time it failed in a way I haven't seen before, the layers separated on a trasition between base layers and the normal layers.Īt this point I knew something was awry, but I still thought that perhaps my settings were wrong (I thought that maybe the base layer exposure was really wrong and it caused it to separate or the lifting speed was too fast) as this was a new resin, even though it's the same kind, but after other prints failed with changed settings the resin became my prime suspect, as everything printed perfectly with the same printer and settings with my previous bottle of resin. Here's a comparison between an old print (the bright one) and the new print (the dark one)Īt first I thought that maybe it just needed more time in the oven, but even after a long time it didn't change. When the first model with the new resin failed, I've noticed a strange difference between prints using old resin, and the new one, namely the old ones would glow in UV light, brighter the more cured they were, and the new ones wouldn't glow at all. But since I started printing with a new bottle of resin (the resin was exactly the same and the recommended usage date is still more than a year away), as my old one already almost ran out, I haven't had a single succesful print. I've used my first kilogram of resin on my Photon Mono and then Photon Mono 4k with great results, and basically no trouble.
