BASF Forward AM (BASF 3D Printing Solutions) Ultrafuse HiPS, TDS v2.2 (13.11.2019), printed specimens, XY 'Flat'. Specimen print settings are not stated; recommended processing on the sheet: nozzle 240-260 °C, bed 100-120 °C, 40-80 mm/s. Product is discontinued (Forward AM product page) but the TDS is still served by Forward AM.
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.
FDM HIPS and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than SLA Resin Elastic 50A?
FDM HIPS is stronger: its tensile strength is 18.4 MPa against 3.4 MPa for SLA Resin Elastic 50A (5.41x).
Which is lighter, FDM HIPS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,023 kg/m³ for FDM HIPS.
Which is lighter for the same job, FDM HIPS or SLA Resin Elastic 50A?
For the same stiffness or strength: FDM HIPS is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Which is more ductile, FDM HIPS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 1.4% for FDM HIPS.
