5052-H32, Kaiser Aluminum tube & pipe typical datasheet (mechanical, CTE, melting); MIL-HDBK-5J (Poisson, density, specific heat)
Formlabs Elastic 50A Resin V2 (FLELCL02), TDS Rev. 01 24.01.2024; parts printed on Form 3, 100 µm, Elastic 50A V2 settings and post-processing; tensile on Die C specimens cut from printed sheets after 3+ h at 23 °C.
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
SLA Resin Elastic 50A is 3D printed: its properties depend on build direction and print settings; these are typical values.
