Instead of having several countractors work on seastead, wouldn’t it make more sense to use a 3-d printer to manufacture the entire structure? 3-d printers have been used to print polymer materials already, many of which offer protection from sea-water corrosion. I know building a large-scale printer is a challenge because a specific temperature range is needed for operation (at least for the process involving polymers).
Of course polymers aren’t the only materials to use. Large scale 3-d printers are more feasible for concrete (already being considered for residential construction). An earlier post mentions using foam and concrete to make a seastead.
Does anyone know of any other possible barriers to large scale 3-d printing besides heat?
