Example applications of this lightweight shape changing structure include concentrators, mirrors, and communications antennas that are able to dynamically change their focal point, as well as substructures for solar sails that are capable of steering through solar winds by altering the sails׳ subjected area.
The most space-consuming part of these manufacturing facilities (and the source of most bottlenecks) is the finishing and shipping area, which handles the many different lightweight shapes that are produced in various steel grades, heat treatments, and surface conditions and are made to many specific customer orders.
Instead of using steel to build certain high-strength components of an airplane, for instance, Carbon3D would be able to 3D print a lightweight alternative by shaping plastic into a form previously impossible to manufacture.
