In this episode we talk about 3D printing on Earth and in Space. We have a range of guests from the physics' soft matter group: Mazi Jalaal, Jackson Wilt and Olfa D'Angelo. Soft matter is a type of soft material, examples include tooth pasta and chocolate spread. As you can imagine, it is harder to print these materials than solid materials. We talk about what soft matter is, what the challenges of printing it are and finally how printing it in space is different than on earth.
