While the headline-grabbing stories of 3D printing in construction have largely focused on extruded concrete homes, a quieter but perhaps more revolutionary shift is occurring in the sector. High-performance materials—specifically fiberglass composites, carbon fiber, and printed metals—are moving from aerospace and automotive labs onto the job site, promising structures that are lighter, stronger, and far more geometrically complex than their concrete counterparts.

In the prefab and modular space, Cover has carved out a solid niche by treating small homes like precision-built systems instead of one-off backyard projects. Their work is less about flashy architecture and more about repeatable construction logic that actually works in the field.
