Systems and methods for manufacturing articles in space

A device for fabricating an article with a pre-defined shape comprising:

• a frame comprising a wall defining a radial dimension of said article;
• a reservoir comprising a liquid and being in fluid communication with a port in contact with or in close proximity to the wall;
• an actuator in operable communication with said reservoir and configured to induce flow of said liquid towards said port;
• a control unit configured to control said actuator to induce flow of the liquid so as to substantiality fill a lumen enclosed by said frame and to shape said article under microgravity conditions;
• wherein the microgravity conditions is a gravity of less than about ⅕ of the gravity on the Earth surface;
• wherein said article comprises a plurality of curved surfaces in contact with an ambient space;
• and wherein the device is devoid of a membrane in contact with the plurality of curved surfaces;
• wherein said control unit is configured to:
• (i) receive said pre-defined shape;
• (ii) calculate a volume of the liquid sufficient for shaping said article solely based on a surface tension of said liquid, a dimension of said wall, and acceleration force exerted on said device;
• and (iii) to control said actuator to induce flow of the liquid according to the received pre-defined shape.
