Hi,

I am planning to use the Formlabs 50A V1 elastic resin for a project in my research lab and the first part was to characterize the material properties. I was able to do tensile testing and estimate the Young’s modulus and Poisson’s ratio. I was running the model that I wanted to create on FeBio to simulate it and as I am using a neo-hookean material model, I would need to put in the density of the material post-curing. If there is any information on the post-cured density, I would really appreciate it if it could be shared with me. Thanks!

Thanks for the question!  
The post-cured density is 1.0 g/cc. We will add it to the TDS in the next revision round, but currently this spec can be found [here](https://formlabs.com/support/Density-of-selected-Formlabs-SLA-resins/) (under its previous name Elastic 50A Resin).
