3D Printing Cost Savings

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.
