3D Bioprinting masks using natural ingredients
3D bioprinting is a cutting-edge additive manufacturing technology that involves layer-by-layer deposition of biomaterials to create tissue-like structures, medical devices, or customized wearables. In the wake of public health challenges like the COVID-19 pandemic and the growing demand for sustainable personal protective equipment (PPE), researchers are exploring the use of natural, biodegradable materials in 3D-printed face masks.
Materials Used in 3D Bioprinting with Natural Ingredients
| Ingredient | Function |
|---|---|
| Alginate (seaweed) | Forms hydrogels, good structural integrity |
| Gelatin (from collagen) | Enhances elasticity and biocompatibility |
| Chitosan (from shellfish) | Antimicrobial, breathable, and biodegradable |
| Cellulose (plant-based) | Mechanical strength, natural fiber for filters |
| Carrageenan | Gelling agent, bio-adhesive |
| Starch/Polylactic acid (PLA) | 3D printing base material, compostable plastic |
