ISP3: In-Situ Printing Plastic Production System for Space Additive Manufacturing, Phase I

Metadata Updated: February 28, 2019

The ability to "live off of the land" via in-situ resource utilization has long been recognized as a key capability for enabling the affordable development of space. While most of the focus has been on the production of bulk quantities of rocket propellants such as Liquid Methane, Liquid Hydrogen, and Liquid Oxygen from extraterrestrial water and carbon dioxide sources, there has recently been an increase of interest in the production of structural materials as well from in-situ resources, particularly materials that can be used for Additive Manufacturing.

For this Phase 1 effort, Altius and its team members propose development of an In-Situ Printing Plastics Production (ISP3) system, that can take methane and oxygen inputs from various in-situ sources, and convert them into High Density Polyethylene (HDPE) filaments for use in a fused deposition modeling (FDM) style 3D printer, such as those developed by Made In Space. In Phase 1, Altius and its team members will simulate and test the three primary subsystems for ISP3: an Oxidative Coupling of Methane reactor that converts the methane into olefins and water, an olefin separation membrane that separates olefins from other outputs of the OCM reactor, and an innovative polymerization reactor that does not use physical catalysts for initiating the polyethylene polymerization reaction. Successful completion of these experiments and subsequent scaling and process refinement tasks will result in an updated ISP3 process design for Phase 2, raising the TRL of ISP3 from TRL 2 to TRL3. Phase 2 will focus on production of an integrated brassboard ISP3 prototype capable of producing small quantities of HDPE filament from methane and oxygen inputs. This will raise the system TRL to 5.
