- It is useful to do in-situ 3D printing of 250 kW Windmill Towers with metal 3D printing using WAAM.
- Possibly with a sort of combination of the WAAM/D3D Metal Printer and a Hangprinter (Possibly using 3 or more construction cranes arranged in a polygon with each verticy being a crane)
Cost of a 200' Tower, 4' Diameter, 1/4" Wall Thickness
- Metal 3D printing - with MIG welders, 250 amp each at 30V
- Welding wire - $68 for 44 lb - [1]
- Alibaba shows 50 cents per lb - [2]
- 12' length of diameter. 12 SF per foot of height. 6" build per hour. 400 hours for tower, or just 17 days. Could possibly increase to 12 welders, at 8 days for the tower.
- This tower is 24000 lb - 120 lb/ft
- It would be useful to make wire for reduced cost. If produced from scrap, tower could cost not $12k at Alibaba costs, but much less.
