The 3D Printer was developed in 2014. The printer works by extruding heated plastic, which builds up layer by layer.

NASA plans to 3D print construction technologies that will be used on Mars and the Moon to continue further exploration

They plan to put in place a lunar terrain vehicle, habitable mobility platform or lunar RV, and surface habitat on the moon in the future

In order to do this, NASA must increase the readiness of the technology and its ability to create large-scale 3D printed structures

NASA is currently working with ICON, a construction technologies company, on plans to 3D print large-scale structures beyond earth.

3D printing in space started in 2014 with the ISM project

The ISM project tested the possibility of printing in space. The first printer was developed by Made in Space

Made in Space developed the printer through a fused filament fabrication process, which feeds a thread of plastic through a heated extruder and onto a tray

During these tests, it was demonstrated that 3D printing works normally in space.

Made in Space developed the Additive Manufacturing Facility (AMF) that prints using a variety of materials

One of the first parts printed in space was a wrench

The printer uses recycled material, which saves flights from carrying a large supply of 3D printing material

Made in Space launched the Made in Space Recycler which investigated the materials that are suitable to be recycled into 3D printing filament.

The International Space Station requires spare parts from earth, so NASA has recently been using 3D printers to recreate the parts needed

3D printers provide NASA with a "machine shop" on board. The 3D Print hardware was launched in the fall of 2014.

NASA uses Acrylonitrile Butadiene Styrene (ABS) plastic and other materials for the prints

The prints are uploaded from earth to be printed in space.

Benefits: Printing in space reduces the time it takes to get parts to space. Because of this, it is cheaper to provide parts for the astronauts.

Printing in space allows astronauts to create parts in space without having to get the parts from the earth.

3D Printing increases the quantity and quality of these parts.
