Imperial College London were funded by the Centre for Defence Enterprise (CDE) to develop 3D-printed physical representations of lower limb bones, including realistic internal structures, for use in assessing blast injuries.

So far, individual 3D-printed lower limb nylon surrogates have been tested and found to fracture in a similar way to human bones. This could help improve research into assessing blast injury. Next steps for the project include the assessment of a wider range of materials for use in 3D printing, including composite materials, which may behave in an even more similar way to bone.

This development has the potential to eliminate the need for ethically controversial human cadaver material, while providing a more realistic injury response than can be achieved with non-breakable surrogates.

Dr Andrew Phillips, Imperial College London says:

CDE funding has allowed us to rapidly develop a research-based idea towards a product that has clear application in the assessment and mitigation of blast injury.
