A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Highly Stable Low‐Temperature Phosphate Glass as a Platform for Multimaterial 3D Printing of Integrated Functional Microfluidic Devices

open access: yesAdvanced Engineering Materials, EarlyView.
A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.
