 - **FDM/sintering workflows**:  These are cool and leverage tools from above
     - [Virtual Foundry](https://thevirtualfoundry.com/) sells a PLA+metal particle filament. Print in any FDM printer (a filament warmer helps...the filaments are quite brittle), then debind and sinter in a kiln to make metal parts.  Lots of different metals, also glass(!) and lunar regolith simulant(!)
