Bioprinting (lecture 2) Flashcards
What is the definition of bioprinting?
The use of 3D printing technology with materials that incorporate viable living cells
What are some bioprinting methods?
- Scaffold free
- Extrusion
- Projection
- Volumetric
How does scaffold free bioprinting work?
- Spheriod seperation
- 3D design
- 3D bioprinting on a needle array
- Decannulation maturation
How can the printability of bioink for extrusion printing be tested?
with a rheometer
What is a shear thickening material
Acts like a solid at high shear rates
What is a shear thinning material
Material that becomes less viscous at high shear rates
What are the steps of projection/stereolithography bioprinting?
- Coating/dipping
- Light exposure
- Separation/letting matterial refill base
- repositioning
- Repeat
Which three components does volumetric printing combine?
speed, size, resolution
What is an example target for scaffold-free printing?
Thyroid (solid organ)
What is an example target for extrusion bioprinting?
cartilage (flat organ) or blood vessels (tubular organ)
What is an example target for stereolithography printing?
Liver (solid organ)
