Abstract
The aim of this paper is to perform preliminary analysis on the possible use cases of 3D-printed polylactic acid (PLA) in the field of rocket engines. Specifically, the use of 3D-printed PLA for the oxidizer and combustion chambers of a hybrid rocket engine is studied. The effects of different 3D printing parameters on the pressure-holding capability of printed pressure vessels is studied in more detail. Problems arising from the use of volatile gases such as nitrous oxide with PLA are analyzed and solutions proposed. Test firings of a hybrid rocket engine using different printed parts are performed.
