Type I collagen-fiber bioink
SUMC Ink
Collagen fibrillar networks for construct reinforcement and tissue-engineering research.
| Composition | Type I collagen fibers |
|---|---|
| Gelation | Physiological-temperature gelation with formation of a fibrillar network |
| Rheology | Shear-thinning behavior for extrusion and shape retention |
| Printing temperature | 10 °C recommended; reported stability at 15 °C over 12 hours |
| Storage | Below 5 °C; freezable, according to the catalogue |
| Concentration / geometry | Concentrations ≥5% support stable freestanding structures; overhangs require support |
| Recommended conical nozzles | 3%: 22G–25G; 5%: 22G; 7%: 20G–22G |
| Ready-to-use format | Sterile 3 and 5 mL cartridges; compatibility with the selected bioprinter to be confirmed |
| Other formats | Powder for custom formulations; custom formats on request |
Catalogue evidence
Reported properties & results
- Reported human fibroblast viability of 70–90% under tested printing conditions
- Reported increased fibril homogeneity and proportion of striated fibrils versus pure collagen
- Higher concentrations increase fibril-network density
- Reported fibroblast attachment and spreading within the gel
Results summarize the catalogue’s tested formulations and conditions. Confirm the protocol and formulation relevant to your experiment with MAKBY.
