I'm new to 3-D print. Wondering if a circular bottle shape, 12 cm. in ht. and 5 cm. dia., will lose shape due to gravity in the print process?
Thinking that Strong and Flexible might work, with wall thickness of 1.5 mm. Shape will under pressure to some degree and so need a measure of rigidity, as well.
Given that S&F is printed in an SLS type 3D Printer I don't think it would sag, especially given that the printer's tray is as full as possible with assorted prints so each layer should have time to cool before another layer of powder is put down and the laser makes another pass. This is mostly speculation/assumptions based on my limited knowledge thought.
You need to look at a couple of the YouTube videos. The WSF printer fully supports every part of each layer as it is built up. There is almost zero chance for any sagging because the support powder below is not removed until the whole block is fully cooled.
