Bioprinting in microgravity might enable mass production of organoids and complex scaffolds, which can potentially provide cost-effective alternatives to animal studies and contribute to artificial organ development. Bioprinting in 0 g should produce more viable cells than in 1 g due to the absence of thickeners that can affect cell viability. This has the potential to contribute to medical advances on Earth and to benefit NASA missions, the commercial space industry, other government agencies, and the nation.
