They mention the hull is made of "syntactic foam".
It seems this is a composite of (glass,ceramic,etc) microspheres in a resin matrix. They mention in the bbc video that they glue blocks together and machine them somehow - how does one machine such a composite?

[edit] yet more:
"Syntactic foam flotation products are available in formulations for shallow water foam to those capable of reaching the bottom of the Mariana Trench."

"The HZ Grade of syntactic has been formulated to survive the deepest depths of the ocean. This class of syntactic will survive crush pressures greater than 20,000 psi making for safe operation in the Hadal Zone.
