Additive manufacturing in the new space economy: Current achievements and future perspectives

In recent years, the realm of space exploration has undergone a transformative shift, marked by the emergence of a thriving new space economy. This evolution has not only redefined existing space infrastructures and services but has also democratized access to space, accelerating exploration endeavors. At the core of such evolution is additive manufacturing (AM), a groundbreaking technology that has fundamentally altered the landscape of designing and producing launchers and space systems. AM not only enhances the efficiency of existing space missions but also unlocks novel avenues for space exploration and the establishment of sustainable human settlements beyond Earth. This paper provides a comprehensive and current exploration of the industrial catalysts driving AM adoption across key space domains. It delves into existing applications and uncharted frontiers, exploring innovative advancements while spotlighting industry gaps and obstacles. Motivated by the maturation of AM technologies, the proven track record of additively manufactured components in space missions, and the surge in research and investments aligning with major space market trends, this paper aims to provide aerospace and manufacturing communities with a panoramic view of present and future opportunities for AM within the rapidly expanding new space economy. Additionally, it sheds light on the profound impact and momentum gathering in this field, all the while examining the significant challenges that demand concerted attention.
