From Cost Savings - we have:
3D Printing - $26k
Basic figure of feasibility is 20 lb/day Supervolcano-style extruder print rate per print head. 4-head machine is capable of 560 lb print mass per week. A 12 machine print cluster would thus produce around 6000 lb of building materials per week, enough for a house every 2 weeks.
See detailed breakdown spreadsheet: [1].
Detailed List
- See the various Seed Eco-Home 3D Printing Substitutions.
Phases - Low Hanging Fruit - $12k Savings
- -$2k lumber blocking
- -$3k nonstructural infill of excess framing
- -$1k interior wall modules - are all non-load bearing and can be substituted immediately
- Includes PEX holders, electrical boxes, pvc holders, wire holders next to boxes, other known wire holders for main utility channel; penetrations; fans; through-wall fans; knockout adapters; pvc; pvc adapters; etc.
- -$3265 in trim [2]
