Researchers from the Buchmann Institute for Molecular Life Sciences at Goethe University in Frankfurt am Main, Germany, have used the microArch S140, a microscale 3D printer from Boston Micro Fabrication (BMF), to help fabricate miniaturized vessels called hydrowells for culturing 3D cellular spheroids under microgravity conditions. The effort was part of the Spheroid Aggregation and Viability in Space, or SHAPE, experiment, which is supported by the German Aerospace Center (DLR) and will be performed aboard the International Space Station (ISS), where scientific research is performed in low-earth orbit.
