Feedstock Preparation
Powder Conditioning and Filament Production
Feedstock preparation including powder sieving, drying, and conditioning for SLM; filament extrusion from recycled polymer for FDM.
Purpose
Feedstock preparation including powder sieving, drying, and conditioning for SLM; filament extrusion from recycled polymer for FDM.
Context
Child of L2-MFG-3DP within the Lunar Ark system
Principles
- ▸Powder sieving to 15-45 um range for SLM
- ▸Vacuum drying removes moisture
- ▸Filament extrusion from recycled polymer (L1-WMS)
- ▸Quality control via particle-size analyzer
- ▸Closed-loop with L1-WMS recycling
Typical implementations
- ▸Industrial powder atomisation (terrestrial)
- ▸ISS Refabricator filament recycler heritage
- ▸ESA powder preparation R&D
Lunar considerations
- ▸Closed-loop polymer recycling reduces resupply
- ▸ISRU metal powder from L1-MFG-SMELT atomisation
- ▸Long-life feedstock-prep equipment
