building rockets with the giant cnc machines in this way,

would be extremely fast.....

 

question is how about from orbit?

 

once the escalator is built.

 

some parts 3d sintering printer,

others from subtractive....

 

to make the cube directly from space.

 

metal casting in orbit.......

 

possible?

 

when zero gravity?

 

if there is a dedicated compartment

that receives bits of metal, or in powder form,

and melts it from within the compartment as a whole

and presses it? as a compression room of sort, as a cube,

then unfolds itself like a box when the metal is cooled down?

walls aligned with wiring, like a toaster, and the crucible

is within. hmm no compression necessary maybe.

or taken the red hot metal cube then compress it from a second compartment,

but it would cool down way too fast.. if compression is needed that is....

 

just thinking faster way to build spaceships....

 

the crucible then should be a rectangle with a open top,

and once the metal is contained, (which is another factor

as it is zero gravity) the open top, will have a cricible cover

descend on it to cover the opening. then the heating begins.

 

until the metal bits are collected into the crucible,

until the top lid is pressed from top down (so no metal bits escape)

outer walls of the crucible can be temporarily used very strong magnets

pressed towards the crucible walls from all sides. metal collected,

lid closes,

 

then the magnets retract, box unflods, leaves,

another toaster compartment wraps around the crucible,

then begins heating.

 

may need to go for it few times adding more metal bits if the volume isn't enough,

but if the magnetization is evenly spread and strong enough, once may be enough?

 

then you got the metal block for subtractive manufacturing in space.......
