Collagen fiber is a naturally derived protein filament obtained from animal sources, most commonly bovine tendon. It is supplied as fiber bundles with anisotropic, direction-dependent stiffness. Collagen denatures above about 65 °C, is colonised by bacteria within a few days at room temperature, and loses strength after repeated freeze–thaw, so it needs cold-chain storage and fresh preparation. It can be used in medical simulation to represent fibrous, load-bearing soft tissue.

• High-temperature sterilisation — Collagen denatures above 65 °C; use silicone for applications requiring autoclave sterilisation.
• Extended room-temperature storage — Bacterial colonisation begins within 3–5 days at ambient temperature; maintain cold-chain storage or use gelatin alternatives.
• Repeated freeze-thaw cycles — Ice crystal formation destroys fibril cross-linking after 2–3 cycles; prepare fresh material each session.
