Reconstruction and physical fit analysis of fragmented skeletal remains using 3D imaging and printing

Forensic Science International: Reports, 2020
Physical fit analysis (PFA) entails physically fitting fragmented evidence together to determine shared origin. PFA can be challenging to conduct with bone fragments particularly when fragile, sharp, or embedded in other materials. Three-dimensional (3D)

Pushing the Limits of 3D Color Printing: Error Diffusion with Translucent Materials

, 2015
Accurate color reproduction is important in many applications of 3D printing, from design prototypes to 3D color copies or portraits. Although full color is available via other technologies, multi-jet printers have greater potential for graphical 3D ...

Measuring primordial non-Gaussianity through weak lensing peak counts [PDF]

, 2011
We explore the possibility of detecting primordial non-Gaussianity of the local type using weak lensing peak counts. We measure the peak abundance in sets of simulated weak lensing maps corresponding to three models f_NL={0, +100, -100}.

Pharmacy 3D printing

Biofabrication
Abstract A significant limitation of the ‘one size fits all’ medication approach is the lack of consideration for special population groups. 3D printing technology has revolutionised the landscape of pharmaceuticals and pharmacy practice, playing an integral role in enabling on-demand production of customised medication.

Colored fused filament fabrication

, 2019
Fused filament fabrication is the method of choice for printing 3D models at low cost and is the de-facto standard for hobbyists, makers, and schools. Unfortunately, filament printers cannot truly reproduce colored objects.
