Titanium lattice and foam create a load-bearing floating structure
RMIT researchers combined hollow printed titanium struts with polyurethane foam, preserving open flow paths while adding buoyancy.

Key facts
- Hollow Ti-6Al-4V lattices were made by laser powder bed fusion and filled with expanding polyurethane.
- Large pores remain open, while closed cells inside the struts provide buoyancy.
Context
An open metal lattice can still sink despite its low overall density. Filling hollow struts with foam demonstrates how material and geometry can work together to enable new AM functions.
