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 Tough 2000 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic PTFE stronger than SLA Resin Tough 2000?
SLA Resin Tough 2000 is stronger: its yield strength is 40.4 MPa against 9 MPa for Plastic PTFE (4.49x).
Which is lighter, Plastic PTFE or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 2,160 kg/m³ for Plastic PTFE.
Which is lighter for the same job, Plastic PTFE or SLA Resin Tough 2000?
For the same stiffness or strength: SLA Resin Tough 2000 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Plastic PTFE | SLA Resin Tough 2000 |
|---|---|---|
| Strong rod or tie | 8.9x heavier | lighter |
| Strong beam | 5.39x heavier | lighter |
| Strong panel or plate | 4.2x heavier | lighter |
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 expands less with temperature?
Plastic PTFE expands less: 100 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
