Abstract
This work characterizes 3D printed ceramics after space flight aboard the ISS. Along with water immersion and mercury immersion testing, visual data was collected via SEM, AFM and TEM evaluation. Bulk resistivity was measured via two-point contact probe methods. Cumulative radiation dosage was approximated with data collected from NOAA's GOES system. The SEM micrographs did not provide data for bubbles in the glassy phases of the material, but the TEM data showed bubbles in the polycrystalline structure of the control and experimental batch A specimens. The bulk resistivity testing ultimately revealed that the experimental specimens became less thermally dependent when temperatures varied from 50 °C to 75 °C. This work indicates the need for longer space experiment and radiation exposure durations. Of the two sample batches evaluated, the batch A variant shows promise for future study.
