SpaceCAL (Computed Axial Lithography) - 3D Printing in Space

[Project Manager], project funded by the NASA Suborbital Tech Flight program with a $274,200 budget. 09/2022-present

UC Berkeley

Participating in adapting the CAL printing to function in microgravity for space exploration. Prototyping improvements to post- processing methods in a highly constrained system by using solvent-based and centrifugal methods for resin-part separation. l Developed a data acquisition system using the PIVlab and ANSYS Fluent model to improve the CAL model. Determined velocity fields, streamlines, vorticities, and shear rates of fluids for both printing and post-processing processes. Effect of atomizer design on the performance of Ultrasonic Atomization Micropropulsion System 12/2020–05/2022

[Lead of 8 members team], project received Faculty approval for a $16000 budget. Led in establishing CAD drawings of heat transfer, fluid handling, and storage subsystems for PocketQube satellites.

• The generated thrust-to-power ratio is 42.9 µN/W, 6.4 times higher than that of an electric thruster. l Established CAD drawings of ES calibrators of a sub-micro newton torsional thrust stand, then 3D printed the UAMS and thrust stand and assembled them. Measured the mass flow rate and flow velocity in a vacuum chamber. l Evaluated the effects of hole number (1-800) and hole size (3.5-30µm) on its performance.
