I’ve printed this twice with the same results. I get the entire print, but the middle supports at some point pull away from the model. This wouldn’t be bad, but they take a bit of the model with it and it’s enough to make the repair kind of ugly.
This is the only angle Preform will allow me to print it. I’ve tried from flat to less of an angle. I haven’t rried totally vertical yet, though.I redid most of the supports because preform either gives me too few or such a forest of them that cleaning the supports off is just a bad as trying to repair what I have. I’m using
The model is about 70mm tall and I’m using .35mm supports. I had thought of going to larger ones in the area where the model is pulling away from the supports, but I would probably just get even bigger holes where they pulled apart.
I’m really perplexed because with an earlier version of Preform I printed the model in grey with mush less support and it was fine. The castable was does seem a bit more fragile than gray, but my goodness the sharpness I get the casrable wax.
I’d appreciate any thoughts you have on this.
