The Standup L-Set Reactor Efficiency I rig provides a means for structure operators to decrease material and time requirements for composite, hybrid, and biochemical reactions in their Upwell Refinery structures. Standup is a proprietary system that uses a Structure Autonomous Nanoassembly Device (Upwell) containing integrated template software, a nanoassembler array and sufficient nanomass to enable the construction of a variety of service modules, structure modules and structure rigs when inserted into the appropriate slots on a structure built with Upwell technology. Note: Only one rig of the same type, counting both tech variations, may be fitted at the same time on a structure.
