They are looking to make large light structures as well. They call these systems Archinaut. It is an alternative approach to the Tether unlimited spiderfab.
In November 2015, NASA's Space Technology Mission Directorate (STMD) announced its selection of the Made In Space project proposal for utilizing public-private partnerships to advance Tipping Point Technologies. The NASA funded project, designated Archinaut™, is designed to develop the necessary technologies and subsystems which will enable the first additive manufacturing, aggregation, and assembly of large and complex systems in space without astronaut extravehicular activity. Made In Space is working alongside Northrop Grumman Corporation and Oceaneering Space Systems as subcontractors to develop the Archinaut capabilities.
Archinaut is a technology platform that enables autonomous manufacture and assembly of spacecraft systems on orbit.
