Over the next four years, NASA engineers hope to come up with 3-D printable technology capable of handling liquids aboard the International Space Station without spilling in microgravity. This gives astronauts aboard the ISS the ability to analyze their own biological samples, such as blood, without needing to send them back to Earth.

At the moment, it takes months between the time a sample is collected, and it can be analyzed, as there is no way to do so aboard the ISS. This can create huge delays, and in some cases, can even cause the sample to become compromised. There is also a huge expense involved. The goal of this technological development is to create a system for the analysis of molecular samples without significant intervention or delay.

Another challenge NASA hopes to address with 3-D printable technology is the collection of samples. To prevent spills or air bubbles, astronauts
