Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "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 and SLA Resin Tough 2000 are 3D printed: their properties depend on build direction and print settings; these are typical values.

Questions

Mechanical

Is SLA Resin Elastic 50A stronger than SLA Resin Tough 2000?
