Each of the first plurality of unit cells includes a first plurality of struts and a first node connecting three or fewer struts of the first plurality of struts such that each strut of the first plurality of struts extends through the first node. The microtruss structure also includes a second plane having a second plurality of unit cells. Each of the second plurality of unit cells includes a second plurality of struts and a second node connecting three or fewer struts of the second plurality of struts such that each strut of the second plurality of struts extends through the second node.
