The space factory for space immigrants

It is becoming increasingly possible for humans to build permanent buildings in space, and space factories will be among the first batch of space buildings. Since it is free from the constraints of gravity, under the special conditions of high vacuum, the space factory will become an ideal place to manufacture some rare products that cannot be manufactured on earth. The space shuttle will send the raw materials to the space factory, or use the resources of the planets in the solar system to manufacture and process the required products and then transport them back to the earth. Because there are no hot and cold convection, density, precipitation and other phenomena in space, the purity of medicines produced in space factories is at least five times higher than those produced on the ground, and the pharmaceutical production speed is 400 times faster.
