Continuing the discussion from Announcing Tough Resin + Contest:
Thanks very much for those infos, Chris! That sounds really nice… looking forward to trying out ‘Tough’ in the near future.
I’m actually pretty surprised you didn’t get any resin starvation problems with those thick parts, particularly with what people have said about the viscosity.
I’ve noticed that, particularly on larger parts where the resin level drops and the last layers are small, because the resin tank spends a lot of the ‘duty cycle’ in non-level state (i.e. peeling), the resin tends to collect at the non-hinge end. I’ve deliberately tilted the printer slightly in the y-axis so that the hinge end is lower down than the other end:
It doesn’t look like much, but I believe it helps somewhat if you are trying to avoid adding much more resin to the tank than necessary (so that collection of sludge/jello/particles is somewhat reduced… I still haven’t gotten round to getting a strainer like a few people have suggested, but will do so sooner or later).
I imagine that the higher the viscosity, the more important such a move might be to avoid resin starvation at the hinge end. You obviously have to be careful not to overdo it, and check the back-to-front angle´ so as not to the fill the printer itself up with resin… and maybe there are other reasons for NOT doing this…?
