NASA Flight Engineer Tracy C. Dyson worked in the Columbus laboratory module swapping hardware for a new experiment seeking to demonstrate 3D printing of antimicrobial parts in space. The investigation named Copper Anti-Microbial Prints, or CAMP, is examining the effectiveness of producing medical devices on-demand and how microgravity affect their anti-microbial properties. DNA Nano Therapeutics-Demo 2 is exploring space-manufactured DNA nanomaterials in order to produce therapeutics that may benefit travelers in space and
