yet been applied explicitly to physical fit analysis.”

The scientists compared two different 3D imaging techniques by using mi-
cro-computed tomography, where they utilized X-rays to see the inside of

an object slice by slice and structured light scanning. By generating virtual
3D models and prints of burnt human bone fragments, they tested the suit-

ability of these imaging techniques and subsequent 3D printing for analy-
sis. The researchers ultimately found that 3D imaging and printing allowed

for effective analysis without excessively handling the original fragments.

Limiting the handling of very brittle forensic evidence minimizes damage
and foulness. Moreover, the use of 3D prints opens up a possibility and the

opportunity for a jury to explore the evidence replicas. The use of 3D virtu-
al models and animations also provides 360-degree visualization in an en-

gaging, understandable, and potentially impactful way, improving a judge’s
understanding.

Dr. Brown says: “The application of 3D imaging and printing for physical fit

analysis has many advantages compared with traditional methods. Overall,
the techniques demonstrated by the study add value in forensic investiga-

tion and evidence presentation within the courtroom.”
