About this file
This Statement of Work (SOW) details NASA Kennedy Space Center's requirement for a new extruder with a hardened liner for compounding regolith simulants. The objective is to replace an incorrectly fabricated barrel for an existing extruder, with the vendor offering a discounted demonstration model. The extruder is critical for multiple terrestrial and space manufacturing projects, including the ReMADE project, and will be used in the Granular Mechanics Regolith Operations (GMRO) Laboratory at NASA Kennedy Space Center. The hardened liner is essential for processing abrasive silicate materials like regolith, which can cause significant wear to extruder components, potentially reducing maintenance costs and extending the instrument's operational lifetime.

STATEMENT OF WORK
1. Objective/Requirements A new barrel for our current extruder was purchased but the vendor fabricated and sent us the wrong one. The barrel is required for us to compound with regolith simulant using the extruder to meet milestones for multiple projects. The vendor cannot make the correct sized barrel anymore and preferred to send us a newer version of the extruder that was a demonstration model at a significantly discounted market value. Compounding utilizing this extruder is a critical part of making pellets for a couple of terrestrial and space manufacturing projects that KSC is supporting.
2. Characteristics, Scope, and Specs
A hardened liner is required for the extruder to compound silicates such as regolith simulants. For our compounding, we utilize silicates such as glass or regolith as our filler, which is very abrasive and causes wear to the extruder. The parts that would need to be replaced costs about $25-30k, which is an expensive consumable. Therefore, having a hardened liner greatly reduces the wear and extends the lifetime of the liner. It also reduces the maintenance that is required for the instrument. Therefore, a system that already comes with the hardened liner at this low cost is especially desirable and mitigates our concerns on the current system.
3. Place of Performance Granular Mechanics Regolith Operations (GMRO) Laboratory, Building M7-0409 room 1204 at NASA Kennedy Space Center, Merritt Island, FL.
4. Period of Performance The new extruder will be utilized for years to come as it is a laboratory capability and instrumentation in the GMRO. Multiple projects utilize the compounding extruder, specifically, a project called ReMADE will require the extruder to perform compounding in order to meet near term milestones this FY.
