UK manufacturers have pioneered the use of Direct Metal Laser Sintering (DMLS) to produce titanium implants with integrated "Lattice Structures." These are microscopic, honeycomb-like pores that are printed directly into the structure of the implant.

In 2026, these lattices are engineered to match the mechanical stiffness (Young’s Modulus) of the surrounding human bone. This prevents "stress shielding"—a phenomenon where traditional, overly stiff implants cause the surrounding bone to weaken over time. The porous surface facilitates Osseointegration, where the patient's own bone cells migrate into the implant, creating a permanent biological bond that reduces the likelihood of the implant loosening or requiring "revision" surgery in the future.
