Hello everyone,
there seems to be a lack of resources, even though SLA additive manufacturing is widely used. Would anyone be so kind as to point me towards a source determining the Poisson's ratio of standard photopolymers in cured state? I'd be especially interested in Formlabs Clear resin and Formlabs Tough 2000. Their documentation does not provide a number, unfortunately, and literature results for other resins are surprisingly scarce as well.
Thank you all in advance.
Good day! As for the information, that I found, Poisson's ratio of Formlabs Clear resin is 0.35. Please find the following links as useful:

Hello Vadim,
thank for searching, too. I also encountered the second source you cited, but it refers to the Formlabs data sheet which does not contain any mention of the Poisson ratio. In another paper I found, a value of 0.4 is quoted with the source being a Formlabs data sheet from 2016, which is not accessible anymore.
Thierry Decker thank you too.
Maybe my links are lack informative, because I am a little bit out of field. So, I apologize. But the value od 0.35 I found at the first link, one guy provided some commentary to the origin post with some numbers that may interest you.
