3D-printed struts make foam 10 times stronger

The process embeds struts in foam. PIC COURTESY/Texas A&M

Researchers in the US have developed a hybrid "super foam" that can absorb up to 10 times more energy than conventional padding.

The material combines ordinary foam with 3D-printed plastic columns embedded inside it.

These flexible struts form an internal skeleton that reinforces the foam and improves how it handles pressure and impacts.

The approach resutls in a composite designed to withstand significantly higher forces while remaining lightweight.

The system could improve protective gear, vehicle safety systems, and even everyday products such as cushions.
