About this file
This statement of work outlines requirements for the design and additive manufacturing of zeolite lattices for use in a temperature swing adsorption bed on the International Space Station. The scope of work involves fluid modeling and lattice design to capture at least 4.16 kg of carbon dioxide per day at 3 psia and deliver it at 10 psia. The lattices must be manufactured from either 13X or 5A zeolite material and demonstrate sufficient mechanical strength and cyclic temperature and vacuum operation. The contractor will deliver the fabricated zeolite lattices along with the fluid modeling and lattice design. The period of performance is from July 17, 2023 through September 30, 2023. The related federal contract opportunity is issued by NASA's National Aeronautics and Space Administration Shared Services Center as a special notice for a 3D-printed monolith.

STATEMENT OF WORK (Sample)
1. Objective/Requirements
The objective is to design and additively manufacture zeolite lattices for the full-scale (4 crew members) Temperature Swing Adsorption Bed (AC-TSAC) in the Environmental Closed- Loop Life Support System on the International Space Station, the AC-TSAC receives concentrated dry carbon dioxide (CO2) at one to 3 psia from the CO2 removal system and delivers it at 20 psia to the downstream system for processing. The zeolite lattices should be mechanically strong and capable of adsorbing at least 4.16 kg of CO2 daily.
The current state-of-the-art carbon dioxide compressors, including mechanical compressors and pellet bed compressors, have significant drawbacks in terms of mass, power, and volume. However, Ames Research Center has demonstrated that full-scale printable zeolite lattices can greatly improve efficiency in terms of mass, power, and volume. While most printable zeolite systems can produce lattices of small sizes (e.g., one inch), full-scale prints are required for a crew of four. Nonetheless, fabricating and maintaining the mechanical integrity of these larger prints pose challenges throughout the manufacturing processes, including paste formulation, printing, and sintering.
2. Characteristics, Scope, and Specs
Scope:
Both fluid modeling and lattice design will be delivered with the fabricated zeolite lattices. The zeolite print will be sized to adsorb at least 4.16kg CO2 per day.
Characteristics/Specs:
• Utilizing either a 13X or 5A zeolite material.
• Generating models of the lattice design that can optimize CO2 uptake.
• Manufacturing a zeolite bed capable of capturing 4.16 kg of carbon dioxide at 3 psia and delivering carbon dioxide at 10 psia.
• The part must possess sufficient mechanical strength to be handled without breaking.
Please provide mechanical test data for validation.
• The parts must be able to operate in cyclic temperature and vacuum swing modes.
• Provide data demonstrating carbon dioxide capture comparable to state-of-the-art technologies.
