and he hopes those users will propose science experiments: They could run simultaneous experiments on ISS and on Earth and compare the results, he says.

For example, an astronaut on the long-haul voyage to Mars might get a terrible burn while futzing around with chemicals, and would be grateful for the ability to print out a new patch of skin. Or, looking even further into the future, a Martian colonist might suffer from liver failure but be saved by doctors who could print out a replacement organ.
Those scenarios are far off both in terms of humanity’s spaceflight capabilities and the state of 3D bioprinting‘a rapidly advancing technique in which specialized 3D printers squeeze out biomaterials and cells to build up pieces of tissue, layer by layer.
