摘要： The present disclosure is drawn to bio-ink printer components, methods of printing bio-inks, and multi-fluid live cell printing systems. In one example, a bio-ink printer component can include a bio-ink and a bio-ink ejector fluidly connected or connectable to the bio-ink. The bio-ink can include a buffer solution that is suitable for live cells, and a polymer that includes polyvinylpyrrolidone, polyvinyl alcohol, polyvinyl sulfate, polyethylene glycol, polyester, poly(dimethylsiloxane), cellulose, polysaccharide, or a combination thereof. The bio-ink ejector can include an ejection nozzle and a thermal resistor positioned to heat the bio-ink to form a vapor bubble to eject a droplet of bio-ink from the ejection nozzle.
