This week the International Space Station has received its first and highly anticipated 3D printer which has been installed inside the Destiny laboratory’s Microgravity Science Glovebox by Commander Barry WIlmore.
The new ISS 3D Printer has not been fully tested as yet, but will show how it it possible to print in Zero-G as a proof-of-concept test of the “properties of melt deposition modelling additive manufacturing in the microgravity environment”, says NASA
Its hoped that if the testing goes as planned the new machine will provide a “machine shop” in space that can be developed further for deep-space missions. NASA explains :
“The 3D Printing In Zero-G Technology Demonstration (3D Printing In Zero-G) experiment demonstrates that a 3D printer works normally in space. In general, a 3D printer extrudes streams of heated plastic, metal or other material, building layer on top of layer to create 3 dimensional objects.
Testing a 3D printer using relatively low-temperature plastic feedstock on the International Space Station is the first step towards establishing an on-demand machine shop in space, a critical enabling component for deep-space crewed missions and in-space manufacturing.
In addition to safely integrating into the Microgravity Science Glovebox (MSG), the 3D Print requirements include the production of a 3D multi-layer object(s) that generate data (operational parameters, dimensional control, mechanical properties) to enhance understanding of the 3D printing process in space.
Thus, some of the prints were selected to provide information on the tensile, flexure, compressional, and torque strength of the printed materials and objects. Coupons to demonstrate tensile, flexure, and compressional strength were chosen from the American Society for Testing and Materials (ASTM) standards.”
