Turning Pollen into 3D Printing Ink for Biomedical Applications
- Magazine Article
Scientists have found a way to use sunflower pollen to develop a 3D printing ink material that could be used to fabricate parts useful for tissue engineering, toxicity testing and drug delivery. This pollen-derived ink is able to hold its shape when deposited onto a surface, making it a viable alternative to current inks used for 3D printing in the biomedical field (also known as bioprinting). Such inks are usually soft and delicate, making it a challenge to retain the final product’s desired 3D shape and structure as the bioprinter deposits the ink layer by layer.
