Cartilage is a firm but flexible connective tissue that shapes and supports parts of the body where bone would be too rigid. Anatomists distinguish three types: hyaline cartilage, elastic cartilage and fibrocartilage. The cartilage matrix is the extracellular material of cartilage, made of collagen, proteoglycans and water. Hyaline cartilage forms the thyroid, cricoid and tracheal framework of the airway, the costal cartilages of the anterior chest wall, and the articular cartilage covering the bone surfaces inside synovial joints.
The builds documented on this page are airway and chest-wall cartilage rather than joint cartilage: the thyroid and cricoid cartilages of the larynx, the tracheal rings, and the costochondral junctions of the chest wall.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Polyurethane Foam | White UW Cricothyrotomy Simulator, D'Auria Cricothyrotomy Simulator | Compliant foam standing in for the cartilaginous tracheal rings. | ||
| TPE | Chest Tube Simulator (Brannan) | Thermoplastic elastomer 90A, used together with PVA, printed as single-unit flexible joints between the ribs and the sternum — the costochondral position. | ||
| 3D-printed trachea | Cricothyrotomy Simulator (Calvo) | 3D-printed laryngotracheal model; palpable thyroid- and cricoid-cartilage landmarks, felt through the pork-belly skin overlay.[1] | ||
| Silicone | Cricothyroidotomy Simulator (Gauger) | Thyroid and cricoid cartilages as integrated regions of the 3D-printed medical-grade silicone laryngotracheal model — the superior and inferior palpable landmarks of the cricothyroid membrane. Both are standard front-of-neck-access landmarks and are not separately named by Gauger 2018.[2] | ||
| Silicone | Pediatric Front-of-Neck Access Simulator (Kovatch) | Medical-grade silicone, Shore 45. Thyroid and cricoid cartilages moulded into a single silicone tracheal model; both are palpable through the synthetic skin overlay. Transfer to patients was not tested.[3] | ||
| Cardboard | Cricothyrotomy Simulator (Aho) | A separate piece of cardboard cut to the shape of the thyroid cartilage and taped to the Styrofoam tubing in the superior position — the upper palpable laryngeal landmark bordering the cricothyroid membrane.[4] | ||
| Zip tie | Cricothyrotomy Simulator (Aho) | The lower (inferior) palpable laryngeal landmark, the cricoid ring.[4] | ||
| Filament, e.g. PLA, or resin | Cricothyrotomy Simulator (Kei) | Thyroid- and cricoid-cartilage landmarks integrated in the 3D-printed trachea model and palpated through the pork-belly skin overlay. Both cartilages are implied by the printed model and are not separately named by Kei 2019. Resin lasts more than 100 sessions; filament is cheaper but more brittle.[5] | ||
| ABS | Injection Laryngoplasty Simulator (Lee), White UW Cricothyrotomy Simulator, D'Auria Cricothyrotomy Simulator | Rigid 3D-printing thermoplastic; prints the firm laryngeal cartilage framework (thyroid and cricoid landmarks). ABS cannot be pierced, so a thermoplastic-polyurethane (TPU) framework is substituted where the transthyroid-cartilage approach must be simulated.[6][7] |
