3D iso Rotomoulding?

Found this interesting report on another site and didn’t see it mentioned here anywhere:

Are they still looking for a new Laser builder?

Time to print some Mini650s.

Next stop: container ships. Seriously, in 5 to 10 years. Planes as well.

5000 lbs that is a heavy 25 ft boat.

5000 lbs that is a heavy 25 ft boat.

Depends on if that is the printed weight, or the final fitted weight.

My guess is fitted weight which is on the heavy side but good for rough weather that a patrol boat gets into.

Like Rotomolding, it takes more weight in plastic to get equivalent strength to an ideal fiber reinforced composite laminate. The material strength can't be optimized to the loading like directional composites in a classic laminate.

Imagine a ship collecting plastic in the ocean, recycling it to filament for printing its own barges to haul the trash back to land.  Or islands collecting the trash washed up and printing fishing boats or whatever else the island needs.
