NASA is researching technologies that will support manned exploration beyond the Earth's atmosphere, including a special FDM 3D printer being sent to the International Space Station. Further space applications include:

 

• Printers that use electron beams to melt wire instead of blown metal granules for use in near-vacuum environments

• 3D-printed nozzles and other components of spacecraft engines

• Providing tools astronauts will need during their trip, even if a particular tool hasn't been invented by the time they leave Earth 

• 3D printers capable of fabricating living areas for explorers by using nothing more than local materials and sunlight for power

• Long-duration foodstuffs that can be printed in solid form from powders and water

• Bioprinters capable of producing everything from edible meat for astronauts' protein needs to body tissues and organs for advanced medical care during extended voyages
