| Abstract | Geopolymers (GPs) have emerged as promising building blocks for Martian construction, yet their inherent brittleness and relatively high density hinder practical application and technological implementation. Implanting biomimetic inspiration from long-term evolution into GPs provides an alternative approach to endow the skeleton with fascinating properties such as lightweight, high strength and high toughness. Here, we first develop a basalt fiber-reinforced Martian regolith simulant-based GP ink for direct ink writing that exhibits excellent rheological properties and rapid solid-to-liquid transition, enabling large-scale production of GP composites with customizable biomimetic patterns and controllable fiber alignment. Among these biomimetic structures, the helical pattern shows the highest compressive strength of ~32.2 MPa, enabling the construction of robust engineering components that can withstand high loads. Meanwhile, the 3D-printed suture pattern shows a relatively low compressive strength of ~9.3 MPa, yet excellent fracture ductility with an ultimate strain of ~14% due to the layer-by-layer stress relaxation mode, promising for deformation-resistant materials. |
